Question

how to get a component transformation matrix relatively to its parent assembly?

i know there is a api in toolkit to get a component's transformation matrix, like ProAsmcomppathTrfGet(). but as far as i know, the assembly component path is related with current assembly or current model in toolkit.

how about i want to get a component's transformation matrix relatively to its parent assembly not current assembly.

for example, there is a assembly A, it has a component B who has a component C. instead of using ProAsmcomppathTrfGet() to get path for C to A, i want to get the transformation matrix for C to B.

is it possible to do so? can anyone show me a sample codes? many thanks.

You have already everything in your hand. If the path size is greater than 1, for example 3 your path may have these identifiers 25 11 56, then you know that 25 and 11 are assemblies, 56 can be a part or an assembly, now you get the assembly handle by 25->11 and use the path 11 to get the matrix, you just need to play with the path data. You can’t have a one assembly in session which are different in one other parent. The direction top to bottom or vice versa can be specified within the call, but I think this is known. And it is not related to the current and active assembly, you only need to specify the right handle.
