Illustrator 3D: extrude and revolve vs grouped objects
I want to build a 3D vector graph as in the image below, namely a 3D spiral with numerically specified steps going up. Those specified steps would need to be inserted numerically.
0. When I ungroup the 3D object, it becomes 2D again.
1. When I try to adjust the extrusion depth of a separate subgroup, it seems to be impossible, the 3D settings of the separate object reset, and the overall location & light do not fit the rest of the group any longer
2. When I extrude the ungrouped spiral, the segments are all over the place.
3. The only way I managed something close the desired effect is working with stacked segments copied and displaced on top of each previous one, but this is too tedious and I can not use exact numbers for the extrusion depth (which are absolutely necessary for this graph).
