1. Watch the videos

Dassault Systèmes videos hosted on MySolidWorks: they open in a new tab and a free account is enough. Watch them in order.

2. Key takeaways

1

Auto Route proposes several solutions between two connections; compare them before choosing one.

2

You can ask the route to avoid the model geometry or to pass through reference geometry.

3

When automatic routing gives nothing usable, manual routing in a 3D sketch remains the solution: lines, angle guides, elbows.

4

A pipe's dimensions can refer to its centerline or its outer surface, and a covering (insulation, for example) can be added to the pipe.

Tip

Start with Auto Route even if you plan to touch it up: a route close to the right one is faster to correct than to draw.

3. Do the exercise

In an assembly with two pieces of equipment fitted with flanges:

  • connect them with Auto Route and compare at least two solutions
  • make the same connection by hand in a 3D sketch with two elbows
  • add a covering on a section of the pipe
✓To check: Both routes rebuild without errors and the covering appears only on the chosen section.
