There are a number of reasons why you may want to edit a Part.
When you add a Part, you drag in the Mechanism-Editor. You must edit the Part to give the exact length to the Part. |
In a Part, you can use the CAD-Line for a Slide-Joint and its start-Point and end-Points for Pin-Joints You can also add new Lines, CAD-Lines, and Points for joints in other places in a Part. You MUST add Lines and Points to the Base-Part. |
You can add a Point to a Part and then view the trace that the Point has on the Mechanism Plane during a machine-cycle. There are some rules: see Add Trace-Point. |
You must sketch a sketch-loop before you can add a Profile / Extrusion. . Use the Part-Editor to add the sketch-elements for the sketch-loop. |
Each Cam needs a Cam-Follower. A Cam-Follower must be sketched in the Part as a sketch-loop. You must also sketch the shape of the 'Cam-Blank' with the 3D-Cams. |
For any Point that you add to a Part, you can: •Show the instantaneous kinematic vectors (Velocity and Acceleration) of a Point with the Point Properties dialog-box •Plot motion-values of Position, Velocity and Acceleration throughout the machine-cycle with the Point-Data FB or Measurement FB wired to a Graph FB |
There is a CAD-Line between the start-Point and end-Point of every Part you add to the model. You can add one or more new CAD-Lines to any Parts. You use the CAD-Line to import DXF drawings, SolidWorks parts or STL files onto them. CAD-Lines can be on top of each other, or at different positions in the Part |
See Mechanism-Synthesis. •Three, Four and Five Position Synthesis •Coupler Curve and Coupler Point Synthesis •Function Generation |
Add a Measurement FB between two sketch-elements. See Add Measurement FB The output from a Measurement FB is the dimension, velocity, and acceleration between the two sketch-elements. The output from a Point-Data FB is position, velocity and acceleration of a Point. You can use the output of a Measurement FB or Point-Data FB as the independent variable (X-axis) of a different FB. |
Add a Point or Line added to anchor a Spring FB. |
A Motion-Path FB needs an open or closed sketch-element, sketch-path, or sketch-loop. You must add a Motion-Path FB to add a Pulley - the sketch-loop is the path of the Belt. |
