How to compare the height of acogopoint with the height of the surface on the same x-y coordinate?


Badge

I used the surfacedraper to drape the cogopoints on a surface, i'ts look like he doesn't do anything.

My goal is to compare the height of the cogopoint with the height of the surface on the same x-y coordinate.

My thought was to drape the cogopoint on the surface and compare the height.

I think the problem you are facing is due to the Surface Tolerance parameter. Set it to 0 and You will get a draped height of 2.56

Hi @palhermans, the cogopoint has the elevation of 2.56, the heigt of the surface is 1.23. So the cogopoint has to get a height of 1.23.

Hi, my apologies @sprongandre. You do need to "extract" the coordinates of the draped point. Tested with CoodinateExtractor which gives the 1.23 (in a list of coordinates).

Hi @palhermans, yessss that was the solution, thanks a lot! :-)
