Area moments relative to cplane

Hi there,

I was wondering if it’s possible to compute area moments relative to the cplane coordinate system, not the world axis. Is there a way?

Thanks

Hi @ruy.sevalho,

Here is what is available in Rhino WIP:

Does this help?

Hi Dale,

By the looks of it only do the calculations respective to the world axis are done. At least thats only what appears in the properties of the class. I don’t how much demand ther would be for the properties be calculated respectives to construction plane coordinates also. I’d use it.

Thanks

Did you see the CentroidCoordinates<xyz> properties?

Does Rhino’s AreaMoments do what you need?

Hi Dale,

The CentroidCoordinates<xyz> still uses axis parallel to the world axis, althoug with the origin shifted. I wanted to do the calculations baesd on an axis system not parallel to the world axis. I can always move the geometry and get the results I want, but it woul be nice to have the option to choose which coordinate system are used in the calculations

Thanks a lot
