Creating Patterns

This section explains how to create patterns in Valentina.

Warning: Understanding this section requires previous knowledge of pattern making techniques. If you are new to patternmaking, we recommend you first start with the instructional material listed in the Patternmaking References section.

Pattern creation in Valentina has three stages:

  1. Creating drawings

    At this stage, you draw points, lines, curves and arcs to draft your pattern pieces. Any objects you draw as guides, but which are not part of the final pattern, can be excluded from the workpieces on the next stage.

  2. Creating workpieces

    During the second stage, you select the points, curves and arcs which make up the workpieces. Once you specify the workpieces, you can add seam allowances.

  3. Creating layouts

    On the final stage, you specify the layout of the workpieces for printing or fabric cutting.

The three stages are described in detail below.

Creating Drawings

Main window

Before you begin creation pattern piece you should add one to a pattern. To start, select Pattern piece->New pattern piece from the menu or click on the Add new pattern piece button Add new pattern piece.

If this is the first pattern piece to be added to pattern, you will see the following dialog:

Measurement Types

Select the measurement type to use for this pattern. Valentina supports two measurement types: individual measurements and standard measurements. They are explained in detail below.

Individual measurements

If you want to customize the pattern for a specific person, select the individual measurements option. The following dialog appears when you make this selection:

Dialog individual measurements

Edit the name of the pattern piece or leave the default name unchanged. Then, select whether to use an existing measurements file or to create a new one.

If you already have a file with measurements, use the Existing measurements option and choose the path to the file (click on button Button existing measurements). The dialog will display the Given name and Family name stored in the file to help identify the person to whom the measurements belong.

If you want to create a new measurements file, choose the New measurements option. Then, select the unit of measurement (i.e. inch, centimeter, millimeter) to be used for both the pattern and a path where save the measurement file (click on button Button new measurements).

Note: Once you select a unit of measurement for your pattern, it cannot be changed because pattern formulas don't have enough information for automatic conversion. On the other hand, measurements can be converted. Therefore, you can use measurements with a type other than the pattern unit type.

Finally, select a path for the new measurement file. Filenames for individual measurements end with suffix .vit (Valentina individual table). More information about the file format can be found in the section Measurement file format.

See section Tables of variables to learn how to enter the individual measurements.

Standard measurements

Moved to new Wiki page UserManual:Measurements#Standard_measurements

Tables of variables

The Tables of variables window shows all the variables that can appear in a formula used to draft a pattern. These variables include measurements, increments, line lengths, line angles, arc lengths and curve lengths. To open the window, click on the Tables of variables button Tables of variables.

Tables of variables

Measurements

The Measurements tab is where you can view, enter or modify measurement-related values. In addition, from this tab you can change the measurement table associated with your pattern.

This tab is subdivided into two sections: Personal information and Measurements.

Personal Information

Use this section to enter information about the person for whom you are gathering measurements. Below is a list of the information you can collect in this section:

  • given name
  • family name
  • birth date
  • sex
  • email address

This section is disabled when using standard measurements.

Measurements

This section displays a table of measurement information, with one measurement per row. The columns of the table differ depending on the type of measurement table (individual or standard) associated with your pattern.

The way Valentina will show you the value will depend on locale settings in your system. There are two popular ways describe fractional number:

  • English way : 1234.56 or 1,234.56
  • German way : 1234,56 or 1.234,56

If you will use separators from one locale in another you will have different result from that you expect.

For example if you use German locale value 1.234 will be converted to 1234.0, because '.' is the thousands group separator in the German locale.

For Individual Measurements

Use this section to enter the measurements of the person for whom you are creating the pattern. To modify a measurement value, click twice on its containing cell and enter the new value. After you have finished editing value it will be saved to measurement file automatically.

For Standard Measurements

Use this section to modify standard measurements' base values, size increases or height increases. To modify a value, click twice on its containing cell and enter the new value.

Additionally, you may use this section to view the calculated value for each standard measurement. This is especially useful if you are not using the standard measurements table's default size and height (i.e. base_size, base_height) for your pattern. In that case, Valentina will generate the calculated value using the method described in section Standard Measurements.

Increments

Valentina generates many variables automatically, but you can also define your own. These user-defined variables, called increments (Russian: прибавки), can be used in formulas just like any other variable. In fact, if you associate a size increase and/or a height increase with your variable, Valentina will treat the variable just like a standard measurement. Unlike standard measurements, however, increments are stored with the pattern itself. Therefore, if you need a variable in multiple patterns, you'll have to create it individually for each pattern. Another difference between increments and other variables is that increment names are not translated when you select a new GUI Language.

To add a new increment, click on the plus sign and type in the increment's name. The name must start with an alphabetical character, must not include spaces nor mathematical symbols, and must be unique across the entire list of variables.

To remove an increment, select it and click on the minus sign.

Lines, Arcs, Curves

Every time you create an arc, a curve or a line segment the program creates a variable to hold that object's length and angle (for lines). Some tools create several variables per time. The variable's name is composed from the labels of the related objects. For example, the length of a line going from point A to point A1 is stored in a variable named Line_A_A1. Such variables very useful in situation when need know length of a line (a curve, an arc). This make pattern more flexible to changes and help avoid routine operations.

All variables available in Tables of variables and tools dialogs, see Formula creation.

Note: If you change an object's label, the names of any variables related to that object will change as well. If one of those variables was previously used in a formula, the formula will be broken. To fix the formula, change the old variable name for the new one.

Formula creation

You may use formulas to set segment's lengths and angles in Valentina. A formula may contain the following:

  • constants (integers or decimal numbers)
  • variables (any of the ones listed in the Tables of variables)
  • operators (for a full list see Valid Operators)
    • + for addition
    • - for subtraction
    • * for multiplication
    • / for division
    • ^ for raising a number to an integer power (e.g. 3^2 = 9)
  • algebraic or trigonometric functions (for a full list see Supported Functions)
    • sin
    • cos
    • min
    • max
    • avg
    • fmod

Many of the tools in Valentina accept formulas as input. To simplify the creation of formulas, these tools use a special dialogue that lists all the variables you can use.

Input data

Select the desired variable type (e.g. measurements) and double-click on the variable name to include it in a formula field.

List of variables

Dialog that have more that one formula field don't allow use double-click on the variable name. You should select the variable name and click on button Put variable here near to the right formula field. You may also type the variable name in the formula, but selecting variables from the list provided is recommended for speed and accuracy.

The formula dialogue validates the formula and displays the result shortly after the formula is modified. The dialogue considers the formula valid if the field is not empty and the value can be calculated. If the field represents a length, not an angle, then the value cannot be zero. If the formula is invalid, the dialogue displays an error message. You can find more detailed error message if call tooltip for label with word "Error".

Specifying Angles

You may specify an angle as a constant number or as a formula. Angles are specified in degrees, where 0 degrees points East and angle values increase in a counter-clockwise direction.

Setting angles

Pattern pieces

Each pattern is composed of a set of pattern pieces, only one of which can be active at a time. If you add a new pattern piece, it becomes active automatically. To change the active pattern piece, select a different name from the list of pattern pieces on the horizontal tool bar. The inactive pattern pieces will be painted gray to indicate that they cannot be modified.

When you add a new pattern piece, Valentina automatically creates its first point. This point, colored in red, is known as the base point. All objects added subsequently to the pattern piece are specified relative to one or more existing points thus creating a chain of dependent objects. The coordinates of all objects in the chain depend on the coordinates of the base point. Therefore, moving the base point causes the whole pattern piece to be moved.

Since the pattern piece is a chain of dependent objects, an object cannot be removed if it is used by other objects. Doing so would break the algorithm for constructing the pattern. Therefore, to remove an object in the chain you must first remove all of its dependent objects. The base point is the only exception to this rule.

Deleting the base point causes the whole pattern piece to be deleted. This operation is only possible if the pattern piece is not the last one in the pattern and there are no workpieces created from it. To remove, invoke the base point's context menu (i.e. right-click) and select Delete or press Delete key on keyboard after you select base point.

After adding or selecting next pattern piece in list objects in this pattern piece will available all variables from previous pattern pieces. This is very useful if you want create, for example, sleeve and need armhole length from previous pattern piece.

Points, Lines, Curves and Arcs

Labels

Every point must have a label. To minimize typing, Valentina assigns default values to every label. These defaults depend on the number of the pattern piece and the language selected in the configuration. The convention is to begin each label with the letter of the alphabet that matches the pattern piece number. Thus, the default labels for the first pattern piece will start with the first letter of the alphabet. The ones for the second pattern piece will start with the second letter, and so on. Therefore, for an English configuration, points in the first pattern piece would be labelled A1, A2, A3, etc. while the points in the second pattern piece will be labelled B1, B2, B3, etc.

Each label must be unique and begin with a letter. Labels cannot contain illegal characters:

  • " - "
  • " * "
  • " / "
  • " ^ "
  • " + "
  • " = "
  • " ( "
  • " ) "
  • " % "
  • " : "
  • " ; "
  • " ! "
  • " . "
  • " , "
  • " ` "
  • " " "
  • whitespace character.

When a new point is created, Valentina displays the label right next to the point. However, you can move the label independently from its point. If a label is placed too far from its point, a special line is drawn to join the label to its corresponding point.

Modifying Objects

To modify an object, select the object (or its label) and right-click to display its context menu. Then, select Options from the context menu to display the dialogue where you can change the object's details. Which dialogue gets displayed depends on the tool that was used to create the object in the first place.

Tool options bar

In opposite to dialogs that contain whole tool options, the Tool Options Bar provide quick access to most frequently used options.

Shaping Curves

Spline control points

When you add a curve to your pattern piece, Valentina will initially draw it as a straight line. You will notice two small black circles drawn over the line-- these are the control points which you will use to shape the curve. Each control point is attached to a curve endpoint. As you select and drag a control point away from its endpoint you will see the curve change shape. The curve will bend as if attracted by its control points.

You can also change the shape of the curve via its Options dialog. There you can specify the angle and the distance of each control point from its corresponding curve endpoint.

Deleting Objects

To delete an object, select the object (or its label), right-click to display its context menu and select Delete. Valentina will display a dialog to confirm your intention to delete the object. Click OK to delete or Cancel to keep the object.

Disabled option "Delete" mean you can't delete because some object already depend on this. See also Pattern pieces.

Tools for creating drawings

Zoom

Valentina offers several options for scaling the image on the screen. Zoom in Zoom in and Zoom out Zoom out should be familiar to those who have used vector editors in the past. Zoom original Zoom original resets the scale to the value that was used when the pattern was first created. Fit best Fit best changes the scale of the image so that all pattern pieces are visible on the screen.

When you open an existing pattern file or when you change the active pattern piece, Valentina invokes the Fit best tool automatically. For whole pattern on the beginning and for each pattern piece after each selection next pattern piece.

Like was mentioned above one of those objects is pattern piece base point. Others are curves and point labels. Dragging curve's control points or curve itself will change curve shape.

Note. This function doesn't work during using tool, e.g., creation points, lines, curves.

Creating Workpieces

From all set points, arcs and curves are created the details. The selection is made in a clockwise direction. Each item can only be created from one pattern piece. Then the items can be combined, to establish for them the seam allowances, etc.. Before begin creation detail need be in Draw mode Draw mode. All detail will show up on second scene after changing to Detail mode Detail mode. Each workpiece depend on objects in pattern piece and will be recalculated after each change in pattern piece.

Tools for creating workpieces

Details

New detail

New Detail

This tool adds a new workpiece.

  1. Select the tool.
  2. Select point, arc or curve. Valentina will display a dialog for you to enter some information.
  3. In the dialog box:
    1. Don't close dialog.
    2. Select set points, arcs and curves in a clockwise direction. Note. For creation lines select points at the end of the segment.
    3. Enter seam allowance width.
    4. If necessary, change the bias of seam allowance for each points, arcs or curves.
    5. Click OK to finish.
    6. Change to Detail mode to find the workpiece.

All included objects (points, curves, arcs) stored a like list of points. For correct creation a workpiece all points must have clockwise direction. If do not following this rule can make workpiece broken or some parts can disappear. The following example describe several ways selecting curves for including in workpiece. Note, curved path in draw has a clockwise direction.

Creation detail

The following example show the curved path that was whole included in workpiece. Note, in this example we did not select points on the begin and the end of the curve.

Creation detail

Points on the curve indicate the beginning and end curve segment that need include in workpiece. If select point on beginning and end result will be similar to previous example.

Creation detail

Each curve can be selected many times in one workpiece.

Creation detail

Note, check direction for each curve and use reverse option in dialog Detail for reversion curve if he has counterclockwise direction.

Union of two details

Union of two details

This tool union two workpieces into one.

Some times need combine several workpieces into one. Especially it is hard to do if they was created from difference pattern pieces. This tool work only in Detail mode. After union two details they will be delete.

  1. Select the tool.
  2. Select the first workpiece.
  3. Select the first connection point on the first selected workpiece.
  4. Select the second connection point on the first selected workpiece.
  5. Select the second workpiece.
  6. Select the first connection point on the second selected workpiece.
  7. Select the second connection point on the second selected workpiece.
  8. Click OK to finish.

Note. Be sure that each pair of connection points located opposite each other.

Example:

two details before union

Two details before union

two details after union

Two details after union

Creating a Fold Line

A fold line

To define a line as a fold line, use the Seam Allowance Tool in the Details section. Start the seam allowance at either the top point or the bottom point of the fold line, moving in a clockwise direction, ending at the opposite point of the fold line. Then uncheck the 'Closed' box. The fold line will not be included in the seam allowance. You can emphasize the fold line in Draw mode by giving it a different color.

Creating Layouts

To export a pattern, first create a layout. Valentina version 0.3.0 and later supports the automatic creation of layouts.

All that is required is to create workpieces in the Detail section and set creation options.

Layout creation options

Some options need more detailed explanation.

  • Rotate workpiece. Help avoid situations with workpieces that have convex shape. Those shapes can't be handled by basic algorithm. Rotation value sets angle value for single workpiece rotation around vertex point. For example: 180 means two rotations by 180 degree each. Numbers of rotations can be calculated from the expression 360/angle_value. Warning. Increasing rotation number will increase time for searching best position for workpiece.
  • Layout width. Width of space around workpiece, ie, layout allowance. To calculate width between two workpieces multiply current value by 2.
  • Shift length. Shift length value helps create additional points on workpieces edge. If length of edge is less than shift program then the left edge is untouched. These additional points Valentina uses for moving workpiece along contour edge. The more points on an edge the more chance to find best position. Warning. Sub-optimal length (too small) will increase time for searching best position for workpiece.

All calculation program do in pixels.

  1. Create or open file that already have workpieces.
  2. Click on button Create Layout Layout or select File->Export pattern (layout).
  3. Click on button Layout and set creation options.
  4. Click OK for start generation.
  5. Wait until generation finished.
    Layout window
  6. Click on button Save layout for saving layout in one of the supported formats.
    Save layout
  7. Select path to layout pages, export format and file name for each page. To each name Valentina add page number.
  8. Click on button OK for saving.

This procedure need repeat each time before saving layout.

Export to Wavefront OBJ

In addition to "classical" image formats (.svg, .pdf, .png, .ps, *.eps) Valentina support export to Wavefront OBJ format.

Note. This feature still experimental.

Warning before saving a layout to *.obj file be sure details don't have seam allowance.

Printing Layouts

To print any pattern, first prepare pattern data.

How to prepare a pattern for printing?

  1. Create workpieces (Details).
  2. Create a layout (Layout).
  3. Save or export layout if you wish to view or print this layout later, from another program.
  4. Print from Valentina to your printer or plotter.

To save or export your layout to view or print later, select File/Layout/Export option. Then select Save as PDF, or Export As and select your file format. Saving or exporting isn't required to print a layout. If you wish to rearrange the layout before printing using a vector graphics program like Inkscape, we recommend exporting your layout to SVG.

To print your layout, select File/Layout/Print. Don't forget to use Print preview option if you wanna see how it will look as a printed layout.

To print a large layout across multiple letter-sized pages, select File/Layout/Save As Tiled PDF. You can preview your tiled PDF with File/Layout/Print preview tiled, and print it with File/Layout/Print tiled. Example of tiled layout:

Layout_sheet

Scissor images will help you understand which sides of the paper you need to trim off. Use right and bottom borders for glueing together pages. Information at bottom side of each page will help you understand position of sheets.

Note 1. Valentina for all layout images uses dpi value 96 pixels per inch (ppi). If opening a layout in another program, confirm that the ppi is 96. Include a test square of 10cmx10cm (or other small size) with no seam allowance in your patterns to easily test that the printout is the right size.

Note 2. Some free PDF Readers (for example, Adobe Reader on Windows 8) do not have a ppi adjustment option, and may print your layout at an incorrect size. To view or print your saved PDF layout, we recommend using Inkscape which uses 96ppi as its default setting.

Note 3. Inkscape 64-bit prints a black background for bitmap (png) images. Printing .svg or .pdf files is recommended if you use 64-bit Inkscape v0.9.1. See Inkscape v.0.9.1 bug_1418865
