To Edit Constraints on Rigid Route Sketch

To position and constrain rigid routes, you can apply 3D sketch constraints between route points, segments, and included reference geometry. Available 3D sketch constraints include Perpendicular, Parallel, Tangent, Coincident, Collinear, and Fix. They help navigate your tube and pipe system in the appropriate direction and orientation and constrain it to assembly changes.

To place constraints against geometry outside the route sketch, you can first use the Include Geometry command to introduce reference geometry. If certain constraints already exist on the route sketch, you may need to delete the appropriate existing geometric constraints and dimension constraints to continue placing new constraints.

Place constraints

1. Activate the route containing the sketched route point or segment.
2. Optionally, include external geometry to the route sketch.
3. On the Route tab, use any of the following commands between route points, segments, existing geometry, and included reference geometry.
   • Perpendicular
   • Parallel
   • Tangent
   • Coincident
   • Collinear
   • Fix
4. In the graphics window, right-click and select Done.
5. Right-click again and select Finish Edit.

Show or hide constraints on route geometry

1. Activate the route containing the sketched route point or segment.
2. In the Model browser or graphics window, do any of the following:
   • To show constraints for one or multiple route segment or constrained terminal route point, click Route tab Constrain panel Show Constraints and select the route geometry. To end, right-click and select Done.
   • To show all constraints within the route, right-click in the Model browser or graphics window and select Show All Constraints. To disable the visibility, select Hide All Constraints.

Delete a constraint

1. Activate the route containing the sketched route point or segment.

2. Use Show Constraints or Show All Constraints to display constraints on the appropriate route geometry or the entire route.

3. Right-click the unwanted constraint and select Delete.

   Note: To delete constraints or segments within an auto region, you must first delete the client constraint .
