The Angled Gusset (Perpendicular Chamfers) is a solid five-sided gusset plate for a joint whose two members meet at any angle, not only 90°. It has two straight legs, a base leg and a side leg, that meet at the insert point at the angle you set. Each leg ends in an end edge, Base Chamfer or Side Chamfer long, cut square to that leg, and a single straight edge joins the outer ends of the two end edges. All edges are straight lines with no corner radius. A companion shape, Angled Gusset (Parallel Chamfers), is the same plate with each end edge running parallel to the opposite leg instead of square to its own leg.
It appears in the shapes library under Gussets.

Insert point and direction
The insert point (Base X, Base Y) is the corner where the two legs meet. The outline is one closed polyline with five corners, built from there:
•The base leg runs along +X from the insert point for the Base Length.
•The side leg runs from the insert point for the Side Length, in the direction given by Angle measured anticlockwise from +X. With the default 120° it leans up and to the left.
•At the end of the base leg the Base Chamfer edge runs square to the base leg, straight up (+Y) for an Angle below 180°, or straight down (−Y) for an Angle of 180° or more.
•At the end of the side leg the Side Chamfer edge runs square to the side leg. It is turned 90° clockwise from the side leg direction for an Angle below 180°, or 90° anticlockwise for an Angle of 180° or more.
•A straight edge joins the outer ends of the two chamfer edges and closes the outline.
With the default values the corners are at (0, 0), (−50, 86.6), (−28.3, 99.1), (100, 25) and (100, 0) mm relative to the insert point. The Angle dimension is drawn at the insert point between the two legs, Base Length and Base Chamfer are drawn below and beside the base leg, and Side Length and Side Chamfer are drawn beside the side leg. To turn or flip the gusset, use Rotation or Mirroring X (see Transform).
Properties
Property |
Description |
Default |
Angle |
Angle between the base leg and the side leg, measured anticlockwise from the base leg (which runs along +X) to the side leg. Angle units (degrees). Negative values are accepted. Any value is reduced to the range 0° to less than 360° before the shape is built. |
120° |
Base Length |
Length of the base leg: the distance along +X from the insert point to the end of the base leg. Length units. The property page does not accept values below 0. |
100 mm (4 in) |
Side Length |
Length of the side leg: the distance from the insert point to the end of the side leg, along the direction set by Angle. Length units. The property page does not accept values below 0. |
100 mm (4 in) |
Base Chamfer |
Length of the end edge at the end of the base leg. This edge is square (90°) to the base leg: straight up from the end of the base leg for an Angle below 180°, straight down for an Angle of 180° or more. Length units. The property page does not accept values below 0. |
25 mm (1 in) |
Side Chamfer |
Length of the end edge at the end of the side leg. This edge is square (90°) to the side leg. It is turned 90° clockwise from the side leg direction for an Angle below 180°, and 90° anticlockwise for an Angle of 180° or more. Length units. The property page does not accept values below 0. |
25 mm (1 in) |
Limits
•Base Length, Side Length, Base Chamfer and Side Chamfer cannot be negative; the property page does not accept values below 0. A value of 0 is accepted, but that leg or edge has zero length and the outline has repeated corners at that point.
•An Angle of 0° or 180° (or any whole multiple of 180°) lays the two legs on one line, so the plate has no width at the corner. Use an angle clearly between 0° and 180°. Angles from 180° to less than 360° are accepted and build with the chamfer directions reversed, as described above; check the drawing before cutting.
•The shape does not check that the chamfers suit the leg lengths. If a chamfer is long compared with the legs, or the Angle is very small or close to 180°, the closing edge can cross a leg and the outline becomes self-intersecting, which is not a valid part. Check the drawing after large changes.
•The shape code has no input check of its own. BuildDimensions traps any error and sets the broken state: the shape is drawn with the broken-shape symbol and the property page shows the warning "Cannot build shape from these parameters".
Every 2D shape also has the Transform properties (Base X, Base Y, Rotation, Scale, Mirroring X) and the Polar Array properties, listed after the shape's own properties.
