Cross Scetion Profile

Hello,

I am new to the community and to DraftDesign. I have free Draft Design installed, version - Version V1R4X64

Can anyone point me to the description of how to create a profile plot (cross section from an existing surface in plan view) from existing elevations assigned to a surface of .dwg file?  Is there an automated process to extract X and Z along the line if the surface is provided?

 

Thank you so much

 

Sincerely,

Julia
