I need help. What I intended was a single direction compressed mountain range for some signage. My process was to take the Topographical image and map them out onto a series of planes. I then used a global variable to compress them down to a thickness total of 6". I am now trying to make a solid of the series of splines I created from the topographical data. This is where I'm stuck. I need to eventually turn this into a STEP file for our router to carve out. Thanks in advance for any/all suggestions and assistance.
