Quick Precise Projections
Use the RAY command instead of XLINE command. Besides creating basic construction lines, it also will create lines at precise angles fast and easy. Use the RAY command with osnap "on" when you make your projections. Tip: After trimming, the ray lines becomes lines. The RAY command never extend the line in 2 directions. The line is extended infinite, but only in one direction from the start point. Advantage: Not wasting time cutting construction lines at both ends. It will save you time, once you get used to the command
