Here's a few snap modes that could be useful:
1. Snap to parallel
If there are one or several angled guides around, any straight
line you're drawing will snap to a direction parallel to the direction
of those guides. It's like drawing paraxial lines, except not just
constrained to horizontal and vertical lines. Useful if you need
to draw a lot of diagonal lines for example.
(by snapping, it means it will snap when the angle you're drawing
approaches that angle. You won't be constrained to just drawing
towards those directions)
2. Snap to orthogonal
Same principle as the above, except in a direction orthogonal to
3. Snap to node alignment
When you're drawing an object with straight lines, any new point
will snap to align to existing points of that line. I'm asking this because
creating open-ended rectangles and more complicated straight-line
shapes (examples: folder-like shape, thick U shape etc.) are a pain.
Right now I have to either:
- create several rectangles
- open up any extra segments
Or: create nearly as many guides for snapping as the number of
lines I want to draw (and then I have to delete them)
Or: do a so-so job, open up the align dialogue and tediously align
each group of nodes
In fact, this snapping is the default behaviour I wish I'd have for
paraxial drawing mode, but a snap mode should make a decent
compromise for everyone.
4. Snap to guide point direction
This one requires a guide point object first. When you're drawing
a straight line, the line will snap in the direction of that point. Useful for
perspective drawing, especially if the vanishing points are very
far off from the drawing area.
