New Sketch to Reference Geometry
You can add a sketch to the reference geometry of part which has been added to an assembly model. If the part is not a part of an assembly, this function does not exist in the context-sensitive menu.
In Context-sensitive Menu
- Open the assembly model in the working window.
- Edit a part or create a new part.
- Select the context-sensitive function .
- Select a face, line or three points according to what you selected in the previous step.
- Draw a sketch or read an existing sketch from the sketch library.
- Accept the sketch by selecting the context-sensitive function or cancel it by selecting the context-sensitive function .
Fixing a New Part Automatically to Reference Geometry
Geometric constraints are automatically created for a new part when you add a new sketch to reference geometry, for example to a face or a line in the assembly, as the first phase of creating a new part.
To Face added is created the following constraints.
- A Coincident constraint between the Z axis of the part's origin, corresponding with the part's XY plane, and the selected planar face.
- A Coincident constraint between the part's origin and the origin of the sketching coordinate system of the selected planar face.
- A Coincident constraint between the X axis of the part's origin, corresponding with the part's YZ plane, and the direction point of the X axis of the sketching coordinate system of the selected planar face.
Added to a Straight Line, the following constraints are created:
- A Coincident constraint between the part's origin and the selected line.
- A Coincident constraint between the Z axis of the part's origin and the selected line.
Added to a Circle or an Arc, the following constraints are created:
- A Coincident constraint between the part's origin and the selected line.
- A Tangential constraint between the Z axis of the part's origin and the selected line.
