Ability to set length of line

Recommended Posts

It would be very useful to be able to adjust the length of a line while maintaining that line's arbitrary angle.

 

Ideally I'd be able to view and/or define the length of the entire segment numerically so that I could tell that a given line was N Units long no matter its current angle.

 

Right now I'm able to work around this limitation thanks to Affinity Designer's robust snapping abilities but it would be great to have this as a full feature.

 

If anyone knows a better trick to do this, please let me know. Right now the way I'm achieving this is by making a line along the angle that I want. I then duplicate that line and snap the end of the duplicate to the end of the original to ensure it goes along the same angle. Then I edit one of the two points on one of those duplicate line segments and move that point to snap to one of the further lines along that same angle. After that I delete all the line segments that I used temporarily to maintain that angle at length. It's hard to explain so I'm attaching an animated GIF of the process. In the GIF, assume that the original pedal shape defines the angle that I want my lines to stick to but I want the line to extend beyond the pedal shape.

 

If you can follow that description and/or GIF, you'll see what I'm talking about. Now you can imagine how much more complicated it can get if I want to actually know precisely the length of that resulting line. It's possible...but it gets really hairy.

I just discovered another, better way to extend a line if you don't need to use exact measurements. In regards to my previous example, I could selected the initial line segment and then transformed in proportion and from the center (using the appropriate modifier keys). That will achieve the same thing that I achieved by using the duplicate lines as guides. It still doesn't solve the problem of not being able to use precise measurements but it's a better method than my previous GIF.
