parametric Modelling

Hi,

Is parametric modelling supported in Opencascade? I want to set a dimension(parameter) for a particular feature. If i change the dimension(parameter), the feature should be adjusted for new dimension.

Hello,

This is possible with Open CASCADE and there are OCC-based commercial applications that employ parametric approach (no names for publicity ;-) - but search customer base).

To do so you need to use OCAF (and its part called topological naming). Particular implementation will depend on how you will organize your OCAF-based data model. That is why it's not a direct part of the kernel itself.

There was a sample called Advanced OCAF (part of the Advanced Sample Pack - http://www.opencascade.org/support/products/advsamples/) that demonstrates this parametric modeling approach. Contact OCC for its availability.
