I’ve got a region (a multi-segment line) that I’d like to color with different stroke colors for different segments. Is there any good way to do that? I would consider masking, but that seems to apply only to images…
What precisely do you mean by region and multi-segment line ? If you can be more clear, I am sure someone can help you.
Eg. do you mean a single line with many MidPoints ? Or a logical line made up of several physical lines ? The latter is easy.
apologies -the former - a single line with mid points…
That is even easier, I did not think that is what you meant.
For simplicity, I will demonstrate using Orthogonal lines, of course you can do this to any line type.
1 Single Line with MidPoints
Just draw a line, and double-click on the line to create a MidPoint. It is a single line, so it has a single set of Properties (Stroke, Colour, various type, etc). After that you can move:
- the line (click & drag)
- the StartPoint (red diamond), the EndPoint (green diamond), or any MidPoint (blue diamond)
In the OG context, a drawing tool, I would not call it a segmented line, but of course it is, outside that context
2 Segmented Line
A logical line (intellection) that is made up of more than one physical line. This is not a Group, but a set of lines attached together. Each Start/EndPoint attaches to the Start/EndPoint of another line, note that the line direction is preserved.
Each physical line has a set of properties (Stroke, Colour, various type, etc). Thus we can create great effects.
3 Line Magnet
To be complete, I should show you another technique, used for network or “fishbone” (silly name) diagrams. What we need is subordinate lines connecting to a main line at regular intervals.
- create the main line
- add MidPoints at the interval or position you require.
- MidPoints are automatically Magnets, so you can attach other lines to the Magnets
- when you attempt to attach a line to a Line or a Shape, OG displays all the Magnets (blue diamonds) in the target as red circles, temporarily
- the source line displays as Selected, and whichever Start/EndPoint you are attaching, is highlit
- line direction (attaching to EndPoints, as per  ) is not preserved
- Always use a Grid, and SnapToGrid
- turn it off for short durations when non-Grid manipulation is require.
- it is the fundament for a good-looking diagram, as well as for ease of manipulation
- Regular intervals are then dead simple
Great - thank you!
