I'm having trouble understanding why a multitransform or linear pattern complains about "transformed shape does not intersect support"
Attached is a .FCStd file exhibiting the error. To see it:
Double click TipDepositPlatform_Base to make it the active body.
Activate PartDesign WB
Click on ProtoSupport to select it.
Click on "Create a Linear Pattern Feature"
Change the length to 107
The error (scroll up to top of Task dialog to see it) says "One transformed shape does not intersect support", and the second X turns red indicating the error.
What is the "support" it is not intersecting? It clearly intersects the main body. If you change the length to 106 it is fine. If you make the ProtoSupport extrusion taller the error still occurs, so it is not an issue with the height being the same as the cutout it is filling. If you change the number of occurrences to 3, 4, 5, 6, 7, 8, 9 it is fine, but it complains again at 10.
Is this possibly related to the fact that the sketch creating the 'X' contains crossing lines?
