In part studio this 'hotkey' toggles the construction planes on and off

• 'c'

• 'x'

• 'p'

• 'v'

When building a part in OnShape your choice of plane for your 2D sketch ...

• will effect the orientation of the 3D part.

• is not critical because the part can be rotated.

• can be easily modified later if you make a mistake.

The four basic feature tools in OnShape are:

• extrude

  revolve

  sweep

  loft

• extrude

  sketch

In a parametric based CAD model

• the order of the features are important

• editting a parent feature will effect the child feature

• editting a child feature will effect the paernt feature

• features that are lower on the list may be connected to features that are higher on the list

In OnShape a sketch defines:

• 2D Geometry

• 3D Geometry

• Drawings

• Volume

in OnShape while working on a sketch plane, this colour indicates features that are underconstrained and can be changed.

(a)  

This constraint type creates a right angle between two lines

• Perpendicular

• Concentric

• Coincident

• Tangent
