Workaround for a 3D Add Failure
Read 244 times

In the attached image, I could not 3D Add the cyan and green ACIS Solids.  I tried minor adjustments (Quick Pull on different facets, slight movements, etc.), all to no avail.  The cyan object was in two pieces before I added them, so I was pretty certain it was the green one causing the problem.  I confirmed this when I could not 3D Add a Box to the green object.

So, I selected the green object and Save As STEP.  I then opened the STEP file in a new window and copied it over to the original window.  After aligning the two, 3D Add worked easily.

The only drawback (and possible problem later) is that the file size jumped from 1.1 MB to 6.6 MB.  I am wondering if I will have any problems when I eventually export to STL.

Blow me down that seems like a simple 3D add to me🤔, gotta wonder whats going on under the hood with the cacis add. I presume your using 2019pp or 2019.5pp.

Ive had plenty of these in the past back when using 2017pp, Im still using 2018pp and its been very good😀

Yep thats what I would sometimes when I had a boolean problem, so I mostly saved as a sat file then reopened that file with the offending parts and did my add then. When all was good I imported those objects back into tcw and then continued.

Jeff your file size is a whopper now so save as an intermediate file for good measure before saving as a final step file. Then youve got 2 fall back options.

The next time I've got some time, I will load the file with the problem object and save the entire file as SAT, then load it and save as TCW to see if that solves the problem.

The one problem I noticed with the STEP file was that the color wasn't accepted by the RedSDK Draft mode render.  I should have unticked the 'load materials' option for STEP files.

You could try "SAT Healing" on the objects in the TCW file. It might fix the problem(s) or give you a clue.
