Funny Solid

[Chris Rizzo]

I've got a solid from sw09 that I suspect was created with some non-traditional modeling methods. The curves just don't seem right. Analyze > check solid and it's good. Convert to surfaces the UV lines take on a life of their own and indeed their are a bunch of bad surfs. With the surface uv's you can see how it was created and gets twisted up. I've seen this before but just worked around it.

 

I'm curious as to how a solid body can be "good", but go so terribly wrong when going to surfaces? Seems if it can't go back and forth something has to be wrong with it.

I'm sure the devil is in the details.

Chris, ask for the solid works file.

I have had rare issues like this with SW, but no issues when opening the SW file and then creating surfs from solids.

i've even had bad surfs when i turn the whole solid into surfaces at once but if done 1 by 1 they come out fine

sometimes, I will make a parasolid ... take it into SolidWork with repair turned on ... let it repair itself ... save file either as SW or parasolid ... then back to Mastercam ... if I still get "holes" I either do those faces individually, or find a mirror image of a good surface ...

 

last resort ... make a new patch surfaces ...

If you have the SLDPRT file it is the best to use. when you go to open the file click the options button and import it as trimmed surfaces this way. Mastercam and solid works use the same parasolid Kernel so they work well together. You can also Leave it as solid and just change you wcs if you don't have the solids add-on

Wish I could show you the thing. Perfect part for coons/net. I know he did something nutty in sw. Sometime you just want a surface here and there.

I have this problem from time to time, try it in another format, i use IGES sometimes if i have to.

 

Sometimes if the surfaces come out funny, Ill make some edge geometry and patch it up, but it depends on how good you are at surface modelling. Its quite a PITA sometimes, and some people are better at it than others.
