Hello everyone,
I work on Allplan 2025
I got a problem with the method Vector3D.CrossProduct()
vector_x = AllplanGeometry.Vector3D(1,0,0) vector_y = AllplanGeometry.Vector3D(0,1,0) cross_product = vector_x.CrossProduct(vector_y) print(str(cross_product))
Unfortunately, the result always is None for any vector pair.
Does anyone have any ideas?
Thanks!
Tan
CrossProduct is a mutator method. It does not return a new vector instance but rather modifies the vector that calls it (in your case vector_x is modified).
Hope this helped

Hello guballplan.
It's my fault
I didn't notice the document. It is written clearly.
Thank you very much!

Hi,
As guballplan saied, because it doesn't return anything cross_product will be None.
but
vector_x.CrossProduct(vector_y)
will modify vector_x as => Vector3D(..., ..., ...)
Best

PS: here the documentation
