Draft Trimex/tr

Description
The Trimex tool trims or extends Draft Lines and Draft Wires so that they end at an intersection with another line or edge.

The Trimex tool also extrudes faces created from closed wires. In this sense, it's similar to Part Extrude and to PartDesign Pad.



How to use

 * 1) Select a line that you wish to trim or extend, or select a face that you wish to extrude.
 * 2) Press the  button, or press  then  keys.
 * 3) Click a point in the 3D view, or enter a distance and press.

Trimming or extending is decided from the position of the pointer.
 * If the line is short it can be extended to approach and cross another line.
 * If the line is long and crosses another line, the excess length can be trimmed.
 * If the pointer is moved over another object or edge, the trim-extend operation will snap to that object, so that the trimmed or extended line ends exactly at the intersection with the object. This snapping works even without Draft Snap modes active.

A Draft Wire allows you to trim or extend any of its individual segments, which may affect the entire shape of the wire. In this case, the Trimex tool will work on the line segment that is closer to the pointer. Hold the key to keep trimming or extending the current segment independently of the position of the pointer.

When the selected object is a face, the Trimex tool switches to mode. In extrude mode the extrusion is done in the direction of the normal of the face. For example, if a rectangle lies on the XY plane, it should be extruded in the Z direction. To do this correctly, pressing the key may be necessary to constrain the distance to the Z direction. Alternatively, hold the key to extrude in any direction that is not the normal.

Options

 * Press, or  to constrain the point on the given axis.
 * Hold to restrict the operation to the current segment, and avoid picking another one.
 * In the case of extrude mode, hold to extrude a face in a direction that is not the normal.
 * Hold while trimming to invert the direction of the operation, that is, the other end of the wire will be cut.
