Make Path
Use the Make Path tool to create machine design layout sketches. For example, you can model cam profiles where the tangent relation between the cam and a follower automatically transitions as the cam rotates. A path enables you to create a tangent relation between a chain of sketch entities and another sketch entity.
Once you have created a path, all the sketch entities in the path are selected simultaneously. To select an individual sketch entity in the path, right-click and choose Select Other.
To create a path:
-
Sketch a model to represent a cam and another model to represent a follower.
|
|
Cam
|
Follower
|
-
Make each sketch a block, and position the cam below the follower.
Although not required, making the sketches blocks provides more control of the sketches.
-
Select an arc on the cam and click Make Path (Sketch toolbar) or Tools, Sketch Tools, Make Path.
-
In the Path Properties PropertyManager, under Definition, click Edit Path.
-
Add the remaining sketch entities that form the chain for Selected Entities, then click .
-
Click Add Relation (Dimensions/Relations toolbar) or Tools, Relations, Add:
-
Add relations to the cam and follower to prevent motion that is extraneous to the intended motion between cam and follower.
|
Relations added:
|
-
Add a Tangent relation between the top arc of the cam and the bottom sketch entity of the follower.
-
Click .
Rotate the cam to preview the motion.
