Projected line segments not connected

[nkloski]

Hi!  I have a solid body I imported from another source, and Fusion converted it just fine.  When I project the outline of that body (either as "include 3D geometry" or just a normal projection down to a flat plane, some of the segments are connected, and some are disconnected, like this:

I can break the link and probably do it that way, but that breaks the parametric-centric design.  Anyone know why, in the original object there is an oval, but in the projection, some of the intersections are not carried over?

(unfortunately, I can't share the model as it is under NDA, but I have seen this happen on other models before as well)

Thanks!

Can you Attach the original stl file, or better yet, the native file from which the stl was generated?

Are you aware that there are only straight lines and triangular planar faces in the geometry that you attached? No curves. Not one.

I changed the file from .stl to a solid body. never thought of just pulling the section from the .stl. What I found with the intersect is that the lines were below plane a couple millions of an inch

I have experimented a bit with repairing the stl files and have come to the conclusion that the geometry is rubbish.

Got the center cap converted OK, but the wheel pieces looked like too much work.

Maybe I will give them one more try in MeshMixer.

If it were my work I would use the mesh only as visual reference in recreating native high-quality geometry.

Hello All,

Thank you for providing us the dataset and sorry to know you are facing this issue.

I have added the dataset to our validation set.

Yes, we are currently working on the solution to this legacy issue where projection for some files do not produce closed profiles. We are in the validation phase of the solution.

Although, I can't give exact release date but I am expecting the solution to be available very soon. 

Thank you

I was not sure about the geometry issue at first however the one part did require windows repair in the slicing software before it would print.

Might be off base here but I do remember around Autocad 12 there was an issue with lines not being on the drawing plane. Not all lines just something random and someone wrote a LISP that would place all line ends on plane.
