I am and old user (1999) trying to come up to speed with 2011. I have gone through a lot of the tutorials and need to start this job.
I am trying to construct a off-axis parabolic mirror. With my limited experience I throught I could make a parabolic surface/feature and then create the mirror or cylinder extending it up to the parabolic feature and then suppress the parabolic feature. Is there a better way? Are there any problems as I continue to create the entire assembly??
