Hi, I was wondering if anyone could tell me why I am not able to get a perpendicular line to another line in the attached file using the ‘Perpendicular from curve’ command?
Sometimes it works, sometimes it doesn’t.
The line in this file was actually made using ‘perpendicular from curve’ on an actual curved line, but instead of giving a perpendicular line it would only give what appears to be a tangent line.
So I thought, ok I’ll just use that new line and from it’s end point use the same command, but doing so doesn’t give a perpendicular line - it comes close, but it looks more like about 85 deg.
So I’m thinking, ok, I’ll just use the draw a line option that let’s you specifiy an angle, so in my case I would go with 90 deg.
But I’m starting to think…if it’s not giving a true 90 deg perpendicular line, is the original line I made with that command really tanget? Does is just look that way? yet may also be off by a few degrees.
Suggestions on a better workflow/tool/command use that can give definite results is appreciated.
