ExtendEX

Lengthens a line, polyline, arc or wall at one end until it meets the next element in its way. A wall that reaches another wall stops in the middle of it and joins it.

How it works

1. Point at an element near the end that should grow: a preview shows how far it will go. Click to extend it, then the next one. The tool stays on.
2. Press Enter or Esc to end the tool.
