Project Cut Edges issue

[PACDrafting]

There seems to be an issue with the project cut edges functionality.

Within the solid body part, I have about 100 solids.

I put a sketch on a plane and projected the cut edges. This seemed to slow down the file quite significantly.

I removed the cut edges. Then turned the visibility of solids off that were not required for the cut edges.

I then projected cut edges for the solids that were visible only.

This worked fine and increased performance.

However, when restarting Inventor, all projected cut edges came back.

Any answers here?

Hi

I produced step-by-step and everything work fine.

When i restart Inventor only projected geometry in the visible solids are showed.

But im running Inventor 2012 with the recently launched SP1. Is the same scenario in your case?

Hi

No I'm using Inventor 2011 SP2.

If someone from Autodesk can confirm this is an issue that would be appreciative.

Filtering through the API on sketches.projectedcuts for each sketch, when projected cut is used on a large solid body part file amounts to too many entities and I'm guessing thats why the performance is quite slow.

If the issue I have with 2011 (that is as mentioned in my original question) is fixed in 2012 then this will help us with the work produced.

Thanks Paul.

You might try a 3D sketch and find only the intersecting (cut edges) you are interested in.

Then project these to 2D sketch.

Thanks for the option JD.

However 3D sketching is not so nice to work with especially for the not so advanced user.

Project cut edges is the perfect functionality to use if its fixed in 2012.

Thanks.

OK.

I've found my best option is to generate a 3D sketch and use the "Intersection Curve" function.
