Triad

[1] Click an arrow will orient the

view normal to that arrow.

[2] A black arrow represents

a negative direction.

[4] Click the cyan sphere to return to the

isometric view.

[3] If the cyan sphere coincides with the origin, that means the view is an

isometric view.

Rotations

[1] Hold the middle mouse button down while moving around the graphic

area, you can rotate the model.

[2] Free rotation.

[3] Roll, rotation about screen Z-axis.

[4] Yaw, rotation about

screenY-axis.

[5] Pitch, rotation about screen X-axis.

[6] The type of rotation depends on the location of the cursor.

Bodies and Parts

• A body is entirely made of one kind of material and is the basic building blocks of a model.

• A 3D body is either a solid body, a surface body, or a line body.

• A part is a collection of same type of bodies. All bodies in a part are assumed to be bonded together with one another.

• In <Mechanical>, parts are meshed independently

• A model may consist of one or more parts.

• In <Mechanical>, connections (contacts, joints) among parts must be established to complete a model.

This is the only geometric

entities that will be attached to

<Mechanical> for simulations.
