I see, the path sketch should not within any Body.

Now no more red lines in dependency path, the the bodies are not follow along the path correctly.

Thanks for helping on align the pieces.

I am trying to fix my issue but still not get it. Here is the new dependency graph. No matter how I change the structure I still got red line on PathArray.

I cannot make the pieces align the path, if I change Align to true, an exclamation mark shows on PathArray.

How to make the align work properly?

It is not so convenient to make clone if I need to modify the body. It should have some issue with the STEP export. If I adjust the Crown body sketch distance from 1mm to 4mm toward X axis, the export STEP will not load in Rhino correctly. One interesting thing is that I can load the problematic STE...

I created a Draft->Clone of Crown body, move 4mm toward X, export to STEP, Rhino import the STEP correctly.

I attach the new step file and FreeCAD file

I have opened both step files in FreeCAD and they have different positions. Perhaps it is a Rhino problem? Both Crown.step and Crown001.step are export from the STEP test.FCStd, I export the body one by one. Then import both step file in Rhino, the Crown.step imported correctly but Crown001.step di...

From what origin: the document's? Your FCStd file shows the Crown body's placement to be at (0, 0, 0). Do you expect us to play with its placement then export to STEP? EDIT: I opened "exportproblem.FCStd", then I imported "exportproblem.step" in the same document. The new shape ...

The origin means the Body origin, sorry for misleading. I create a new FC document and made two identical bodies, Crown001 is copy and paste from Crown. only the distance between the body and the body origin is different. I export both bodies to STEP file, Crown and Crown001, then import to Rhino. C...

I have a simple model, the result is not good. I have two bodies, the MainBody is body like watch case, I simplified it as a sketch for crown distance, which is 19mm. I create the crown in another body, then I export to STEP. In Rhino 6 I import the STEP but it looks wrong. If I model the crown from...
