How to create a closed solid from surfaces

Altair Forum User

Hello,

 

is there some sort of 'auto repair' function, that will create a closed solid from a surface CAD model?

And my second question: Is there a way to interpolate a surface between two lines / circles?

To answer the question:

1) You can use the 'GEometry -> Auto Cleanup' Function to try and create closed geometries. For this function, fill in your requested mesh criteria (Size, Angles, etc) and Surface CAD parameters (delete / keep holes etc.) and run the Auto Cleanup. This will at least close smaller gaps in your geometry. If you still have red / free edges, which means your geometry is still open, you can use the edit edges --> toggle function and increase the tolerance to close gaps. For larger gaps you have to create new surfaces (Geometry -> create -> surfaces)

Finally, when your surfaces show only green edges, your geometry is closed and can be transformed into a solid with GEometry --> create --> solids --> from bounding surfs. This will only work if your geometry is actually completely closed, so the 'bounding surf' function is also a check: If you get an error it means that there are still gaps in your CAD

 

2) Use the GEometry --> create --> surfaces --> ruled function to interpolate a CAD surf between two open or closed lines

I have a geometry and I trt to mappable or mesh it but is not done both. Too many time i lost to solve the problem but it not done. I try to mesh 3D quads element, but geomtry is not enclose.

can you help me solve the problem.
