Extracting Sketches
To create a base feature from a 2D drawing, extract sketches to specify the appropriate views. The sketches fold up automatically into the correct orientation as though the drawing were a piece of paper.
Specify which portions of the drawing are the sketches for the front view, the right view, and so on. You can also create auxiliary sketches that are not parallel to the principal view planes.
To extract a sketch for the front view:
-
While editing a sketch, select the sketch entities that make up the front view.
NOTE: You must define a Front view before defining any of the other views. You can box select, chain select, or hold Ctrl and select entities individually.
-
Click Front on the 2D to 3D toolbar, or click Tools, Sketch Tools, 2D to 3D, Front.
A new sketch appears in the FeatureManager design tree.
To extract other orthogonal sketches:
-
While still editing the original sketch, select the sketch entities that make up one of the orthogonal views, such as the top, right, left, bottom, or back.
-
Click the corresponding icon on the 2D to 3D toolbar or on the Tools, Sketch Tools, 2D to 3D menu.
A new sketch appears in the FeatureManager design tree. The sketch folds into the correct orientation to the Front view.
To extract auxiliary sketches:
-
While editing a sketch, select the sketch entities that make up the auxiliary view.
-
Hold Ctrl and select a line in another view to specify the angle of the auxiliary view.
-
Click Auxiliary on the 2D to 3D toolbar, or click Tools, Sketch Tools, 2D to 3D, Auxiliary.
Next, align the sketches.
