Dimension Lines in 3D Views

[Mike Bartholomew]

I am having difficulty placing dimensions on the 3D object where I want them. Look at my library object Bolted Gusset Test. I would like to dimension both horizontal and vertical dimensions in the YZ plane so that when I create a CADDFrom3D view I have all the dimensions in one view (except the thickness). Some really strange things happen, like the horizontal width dimension will move off of the object when I attempt to add a vertical dimension.

Y-direction dimensions have to be in the Y-Z plane and placed above the object (Z coordinates must be positive). The order of the two endpoints doesn’t affect the orientation of the dimension text. They can also be placed in the X-Y plane, but in this case the order of the dimensions affects the text orientation.

X-direction dimensions must be in the X-Z plane. If I try to put dimensions in the X-Y plane, they shift the whole group of dimensions ½ of W to the left in the Y-Z plane.

Z-direction dimensions must be in the Y-Z plane. If I try to put dimensions in the X-Z plane, they shift the whole group of dimensions ½ of W to the left in the Y-Z plane.

The Y coordinates appear to be reversed between the object and the dimension. I’m using my library object BoltedGusset.

Created a new library object named gusset1test that shows the problem behavior better. The vertical dimensions have now been defined in the Y-Z plane, however it appears that in the CADDFrom3D elevation, that the entire object has been moved to the left by approximately 5". The insertion reference point is not at (0,0). This is verified in the library object kFrameTest, where the gusset plates have all been moved from their desired position. The top gussets by about 5". The bottom gussets have moved more. If the vertical dimensions are commented out, then the gussets stay in their intended position. It appears that the vertical dimensioning is causing the problem. This can also be seen in the library object hammerhead. The CADDFrom3D elevation view shows the insertion point not at (0,0). If the vertical dimensions are commented out, then it appears correctly.

objects are placed on the alignment based on their geometric center of the geometry contained in the object with AlignH, AlignV and AlignT parameters. Because DimensionLine object was also contained in the object placed on the alignment, dimension line points were interfering with the placement of the object. Ignoring DimensionLine objects in this process should resolve the issue. This fix is included as of 3.1601.14.
