Construction lines

When you position the Intelligent Cursor over a key point that displays a construction label, construction lines are created from that key point. You can drag the cursor along a construction line and see the appropriate labels display. Clicking causes the position to snap to that point.

The following example draws a box:

1. Select Wireframe tab > Create panel > Line > Continuous.
2. Click to start a line.

   

   Drag along a construction line and click.

   

3. Drag along a 90 construction line and click. The line snaps to give a square intersection.

   

   Note: If the Intelligent Cursor Gridding is enabled, the On label in the above diagrams is replaced by a distance from the last point selected. For example:
4. Drag the cursor down to the original start point and hover. The cursor displays End and the construction lines display.
   
   
5. Drag along the vertical construction line until Intersection is shown.
   
   
6. Snap to the start and finish with one more click when End is displayed.
   
   

This provides a convenient way to enter accurate dimensions.

Note: To disable construction lines temporarily, press and hold the Shift key.
