Description

The Draft Snap Extension option snaps to an imaginary line that extends beyond the endpoints of straight edges. The edges can belong to Draft or Arch objects but also to objects created with other workbenches.

This snap option can handle up to two edged making it possible to snap to virtual intersections.

Snapping the second point of a line to the extension of another line

Usage

For general information about snapping and the related preferences see: Draft Snap.

1. Make sure snapping is enabled. See: Draft Snap Lock.
2. If Draft Snap Extension is not switched on do one of the following:
   • Press the Draft Snap Extension button in the Draft snap toolbar.
   • Press the button in the Draft snap widget and in the menu select the Snap Extension option.
3. Choose a Draft or Arch command to create your geometry.
4. Note that you can also change snap options while a command is active.
5. Move the pointer over a straight edge.
6. The edge is highlighted.
7. If you now move the pointer beyond the endpoints of the edge, you will see a dashed line appear when the indicated point is on the extended edge.
8. The point is marked and the icon is displayed near the pointer.
9. Click to confirm the point.
