I am using blender 2.8 and I imported an SVG file and was able to convert it into a mesh. I used mesh clean up -> limited dissolve to remove extra vertices. I would now like to extrude my object on the Z axis but it will not occur.
Reading older posts, on older version of Blender, seems to indicate I need to modify something to allow Z axis extrusion. but I am not sure where to go in the UI to modify that property?
