Boolean Operation Slow for Complex Models

reilley's picture
Forums: 

When I tried boolean operation for one complex model and a box with BRepAlgoAPI_Common and BRepAlgoAPI_Cut on OCC6.1, the computation is OK! But when tried for two similar complex models with little differece, it took long time to compute, about 4-5 minutes.

I used:
BRepAlgoAPI_Cut aCutCommand(aS1, aS2);

I also tried to substrac the same models using Parasolid solid model kernal, and I got the result in a snap.

Any suggections?

Hi.
I guess that your shapes are "so complex" to be sent.
Be ready to pay for your idle talk in advance.
