Create a new drawing called Areas, and then in that drawing create three triangular areas. We'll start with those.
To get your head around how the convert template works in the Transform template, try converting the areas to lines, and then back to areas. Easy.
Here's what I did to "segmentize" those areas.
1. Use Convert to Convert areas to lines.
2. Transform Split : line coordinates, to create points in a new drawing, called Points, every 10 meters. [Note that this does not inject redundant coordinates into lines: it creates new point objects in a new layer].
3. Copy points from Points and paste into Areas.
4. Read the Normalizing Topology topic, and then run Topology : Clean (generalize). That segments the lines to the position of the points.
5. Use the Select pane to select all points in the Areas drawing, and delete them. If you alt-click on any of the triangular lines, you'll see it's now ben segmentized.
6. In the Transform pane, run Clean : normalize metric on the Areas drawing. This puts all the segmentized coordinates in sensible order.
7. Use Convert to convert lines back into areas. Done.
If you do the above a lot, you can see from the Edit Query buttons in the various steps the SQL each step uses, so you can combine all that into one big SQL query that does everything at once.
Ah... one last thing: If you love the idea of a segmentize transform here's how to get it.
