Sketch positioning ● You can pre-position the local sketch axis

1- select one edge as Horizontal direction

2- second edge as Vertical orientation

3 - select the sketch plane.

4 - Go into the sketcher

result (Action - Object or Object - Action)

B - 1.Action 2.Object 3.Result: point

A - 1.Object 2.Action 3. Result: circle

Intersection (sel. command first)

F&A Hints and Tips - WireframeF&A Hints and Tips - Wireframe

Datum mode ● Create explicit elements (without 3D parameters)

● Add constraints later

Constraints are no more included in the feature but are stored in the constraints tree node

Add 3D dimensions later

You can manipulate datum features because they are free of 3D parameters (by using the compass)

2 - Create a point On Curve (select the bottom edge of the extruded surface)

3 - Line Angle to curve + on support

Structure the specification tree● Use the several bodies to manage the part

● Improve the access to the tree specifications Fill an open_body with about 25 features max.

Use change body to reorder the specification tree as you want (sel. a feature to move before)

Rename the Key features

Encapsulated Show/Hidden (Body and Openbody)● Be aware of the hierarchical display status

If you hide the partbody, Extract.1 will be hidden until you show the partbody again

You can change the status Show/Hidden of Extract.1It will not be displayed while the partbody is hidden

The status (Hidden) of the partbody prevails on the status of Extract.1

● 1 edge + support = 1 dimension

● 2 edges + support = 2 dimensions

● Point + support = normal to support
