I have been leaning SketchUp for about a week for the intent of 3D printing. I have not discovered the answer to this question:
I have done a bit of searching, including on this forum, google and YouTube.
How can I precisely place a circle on the 3D space? My problem, specifically is this. I placed a precise circle at the origin 0,0,0, then extruded it to a desired height. Next I want to place a circle on top surface of the cylinder, centered about the z-axis. As I hover my circle tool, It indicates “on face”, however, it won’t snap to the z axis as I would prefer. Seems like that would be a logical place for the inference engine to set a point. The best I can do is to zoom WAY in and eyeball it and place center near the 0,0 point. But . . . there has to be a better way.
I was encouraged when I found “Entity Info” but to my dismay, there was only radius and segment available. Why wouldn’t there be more attributes here?
Next I found some things re Ruby console. I bet there is a solution here, but I doubted that one would have to learn scripting language just to put a circle on the z-axis. However, I do look forward to learning about the console feature.
So, sorry for the newbie question, but I would love to discover a simple solution.
