How to Create Lines or shapes Perpendiculer/Parallel to existing shape

Thanks for the feedback guys!

To expand on my first question, often I find my self trying to add a rectangle with specific dimensions at an existing vertex, like one on the heptagon. However there is no way for my to create a rectangle and attach it, then rotate it so it is perfectly parallel to side of the heptagon. May if I could anchor the first first connected vertex, then rotate on that point and snap the shape to the line once its parallel? What I usually end up trying to do is to draw a line over the shape’s side, then complete the rectangle using more lines, but there is no way to set the dimensions of that rectangle when creating it from scratch at an angle.

That’s where my second question comes in. If I have a rectangle(or line) that is at an angle, would there be a way to “extend” the shape so that it is at the correct length and width without skewing it?

If there was a way to change a line’s “Distance” rather the the its x or y width dimensions on the workspace, that would be the ticket.

Yes, I am really looking forward to the trim feature. It will be really nice to terminate lines in shapes that overlap other lines shapes. Will this be similar to the subtract boolean, but with more that 2 shapes at a time, including open shapes?

I may look into using freeCad. I am really impressed with Lightburn so far, I feel like it has almost everything I need to create precise models completely within the software, there are just a few situational things that are tricky, and I’m just wondering if I’m missing some functionality or if any other users came up with tricks for these problems.
