Vent PropertyManager

The Vent PropertyManager appears when you create a new vent fastening feature. You must create a sketch of the vent that you want to create, then set the vent options in the PropertyManager.

Click Vent (Fastening Features toolbar) or Insert > Fastening Feature > Vent.


Select sketch segments for boundary Select sketch segments to form a closed profile as the outer vent boundary. If you pre-select a sketch, its outer entities are used as the boundary. You can create a vent of any shape.

Geometry Properties

Select a face Select a planar or non-planar face for the vent. The entire vent sketch must fit on the selected face.
Draft Angle Click Draft On/Off to apply draft to the boundary, fill-in boundary, plus all ribs and spars. For vents on planar faces, draft is applied from the sketch plane.

Neutral Plane (For non-planar faces only) Select a starting plane (remains fixed) from which the draft is applied. This can be the same plane as the sketch plane.
Fillet Radius Sets the fillet radius, which is applied to all intersections between the boundary, ribs, spars, and the fill-in boundary.
