How to create a construction entity (point or line) thru. centroid

[rgrayclamps]

Hi,

For a closed geometries in a sketch, there is a centroid. I need to create a point or construcion line through this centroid. Is there a way to reference cordinates of the centroid via either equations or even API function?

Best regards,

Alex

The following threads reference code for putting points at the center of mass of a body. If you cannot find anything better, you might be able to create a bidirectional extrude from the sketch and use those to place your point. This would be a sub optimal and non-parametric solution.

Hi, Eric:

Thanks for your quick reply! It is good, but no good enough as it is not parametric. It would be nice if we could build an equation to access cordinates of centroid (sketch) so than we use dimensions to locate point/line at the centroid.

The following command line is for a solid model:

Set Point = ModelDoc.CreatePoint2(MassProp(0), MassProp(1), MassProp(2))

Does anyone know what is the equivalent for a sketch (centroid)?

Best regards,

Alex

Could you make the sketch a surface and then find the centroid of that?
