Extrusion Elements in MechDesigner

Do Tutorial 3 before this Tutorial


Terminology:

We use the name 'Solid' for two elements:

Profiles / Extrusions: We add these elements to a sketch-loop,  a sketch-loop is two or more sketch-elements in which their end-points are merged end-to-end.
Imported CAD models: We use SolidWorks (or other CAD) to design these elements, before we import them onto a CAD-Line in a Part.

Solids do not change the kinematic analysis. Solids do change the kinetostatic (force) analysis.

Tutorial Objectives:

Explore and edit:

Sketch-loops
Profiles and Auto-Profiles
Extrusions and Holes

You can use the sketch tools in the Part-Editor for a number of reasons. One reason is to add sketch-loops for Extrusions. However, the Part-Editor is not as powerful as those in solid modelling software. You cannot add complex geometry with the Part-Editor. If you add many sketch-elements to a single Part, the Part-Editor will slow down while you edit or add more constraints.

Do not add a complex sketch.

For Speed:

Break down the complete sketch to smaller, simpler, separate sketch-loops
To specify the position of each sketch-loop, add dimensions from the X-axis or Y-axis for at least one Point in the sketch-loop, and then dimension sketch-elements relative to each other.
Do not dimension a sketch-loop relative to a different sketch-loop
Do not add a constraint between a sketch-element in one sketch-loop and a sketch-element in a different sketch-loop.
