I’m new to Rhino and I’ve been going through the tutorials and finding that the Help and tutorials are better than most other software I’ve worked with, really good for the most part. Now I’m trying to do some of my own drawings and have been able to figure everything out except the most basic thing: drawing a single line. In AutoCad or TurboCad you simple pick a starting point and enter a length and an angle and you’re done. The angle being based on the Cartesian system of 360 degrees. In Rhino all of the examples I can find involve picking a second point to end the line.
I find the Angled option under Line but I can’t get that to work. The instructions there say to Pick the end of the line, but I want to enter a length. And why does it need a base line, why can’t you just enter the angle?
Have you taken a good look at the help section under “Accurate Modeling”? It talks about the various ways of specifying the location of a point. One of the things it discusses is exactly what you are seeking. On the other hand it’s pretty easy to skim right over it.
Aha! That will do it, thanks very much. I had gone through that whole exercise on constraints in the training pdf a couple weeks ago but then forgot about it. I won’t forget it now.
