Profile sketches

Profiles are closed loops that define a cross section of a sketched feature . In an Extrude, Revolve, Sweep, Loft, or Coil operation, you select one or more loops to form the profile. The profile is consumed when a feature is created.

To create a profile, you can sketch single or multiple loops or select existing edges that join together to form a closed loop . All loops selected in a single operation are a single profile .

A closed profile can be easily created using the Close option of the Line command. After sketching two or more line segments, right-click and select Close from the pop-up context menu. A final line segment is drawn back to the starting point of the profile. The command remains active so that you can continue drawing lines.

You can dimension or constrain profiles to prevent them from changing size and shape. If you anticipate that a feature may need to change size or shape in the design process, leave it underconstrained . You can edit the sketch and add dimensios and constraints later.

Procedures

Create a profile sketch

Use any closed 2D sketch (including model edges) as a profile for a feature. Profile sketches are required to create Extrude, Revolve, Sweep, Loft, and Coil features.

1. Sketch one or more loops.
2. On the Model tab, click a sketched feature command (Extrude, Revolve, Sweep, or Loft).
3. Select one or more loops.

   To remove a profile from the selection set, hold down Ctrl and click a profile.

A profile may be a single loop, multiple loops, intersecting loops, or islands. You can sketch on a planar face and select one or more loops as the profile. All loops selected in a single operation are one profile.

NoteTo resize the profile sketch or redefine values in the feature, select the feature in the browser. Right-click and choose Edit Sketch or Edit Feature from the menu. When finished with changes, click Update.
