Primitive Shapes Tools

Tip

  1. Pressing SPACE confirms the current action. On the other hand ESC cancels it.
  2. You can adjust a shape by chaning the properties before confirming.
  3. The mouse cursor will be snapped to a vertex, a center of edge, a center of polygon etc when the cursor gets close enough to them.
  4. Glue and Border Check Properties are common in the most primitive shape tools. See the demo of Box Tool to find out how they work.
