Hi folks.

I posted a thread a few months back (Numerically editing objects) looking for some help wrapping my mind around the basics of modeling in Rhino. While the replies were great and helpful, I still found myself bumping up against a lot of frustrating problems and eventually put this part of my project aside out of frustration.

Unfortunately, I’m now at the point where I can’t put this off any longer, and I’m hoping someone will hold my hand and walk me through a few of the problems I’m having.

I’ll start off with an angled cylinder, like last time:

I’ve realized after I’ve already created and rotated the cylinder that the diameter is wrong. Presumably, I would select the cylinder, use Scale2D, select the cylinder vertex as the origin point, then select another reference point before entering my scale value.

Unfortunately, I cannot figure out what the reference point should be. Selecting the midpoint on the end of the cylinder gives the wrong result:

Am I going about this all wrong? Or is there just a specific Osnap combination that will give me the selections needed to scale the cylinder’s diameter without setting the whole thing askew?

Thanks so much in advance. I feel like such a moron right now
