Create a datum point on COG with creo parametric using relations

Here there is a trick to position an offset datum point on model COG using the following relations:

 

$d1 = mp_cg_x("","DEF_CSYS","")

$d2 = mp_cg_y("","DEF_CSYS","")

$d3 = mp_cg_z("","DEF_CSYS","")

 

where d1, d2 and d3 are the names for the datum point offset dimensions and DEF_CSYS is the name of the default coordinate system.

It works also in assembly mode.

This feature can be saved in the startpart/assembly file.

 

Note: In this video the automatic mass property calculation is disbled by config.pro.

 

Ciao

Gabriele:  It is very good that this can be done.  It's a shame that the base seat of Creo can't do this itself.

 

Does this work with complex curvature or just with fairly basic shapes?

 

Thank you for sharing this idea!
