How to Create Angular Dimensions in BricsCAD

Quick answer: DIMANGULAR annotates the angle between two lines, two linear polyline segments, or the angle of a circular arc, and can also dimension an angle defined by a vertex and two endpoints.

Angular Baseline and Continued Dimensions

Starting from an existing angular dimension, DIMBASELINE inserts an additional angular dimension from the same first extension line origin, while DIMCONTINUE continues an angular dimension from the second extension line of the previous one, the same two commands used for baseline and continued dimensions generally, applied here to angular dimensions specifically.

Dimensioning the Angle Between Two Lines

1. Launch DIMANGULAR. You’re prompted to select a line, arc, or circle, or press Enter to specify an angle directly.
2. Select a line or linear polyline segment. You’re prompted for the other line.
3. Select a second line or segment; the dimension displays dynamically. You’re prompted for the location of the dimension arc.
4. Specify a point to position it. Move the cursor to choose between dimensioning the interior angle between the lines or its supplement.

Dimensioning the Angle of an Arc

1. Launch DIMANGULAR. You’re prompted the same as above.
2. Select an arc; the dimension displays dynamically. You’re prompted for the location of the dimension arc.
3. Specify a point to position it.

Dimensioning an Angle from a Vertex and Two Endpoints

1. Launch DIMANGULAR. You’re prompted the same as above.
2. Press Enter. You’re prompted for the vertex of the angle.
3. Specify a point.
4. You’re prompted for the first side of the angle; specify a point.
5. You’re prompted for the other side of the angle; specify a point. The dimension displays dynamically, and you’re prompted for the location of the dimension arc.
6. Specify a point to position it. Move the cursor to choose between dimensioning the interior or the exterior angle.

Frequently Asked Questions

Can I dimension an angle without selecting existing lines or an arc? Yes, press Enter at the first prompt to define the angle from a vertex and two endpoints instead.

What’s the difference between dimensioning the “supplement” versus the “exterior” angle? It depends on the method: dimensioning between two lines lets you toggle between the interior angle and its supplement, while dimensioning from a vertex and two endpoints lets you toggle between the interior and exterior angle instead.

Can I add a chain of angular dimensions from one I’ve already created? Yes, use DIMBASELINE for an angular baseline dimension from the same origin, or DIMCONTINUE for an angular continued dimension from the previous one’s second extension line.

Can DIMANGULAR work with a circle, not just an arc? The initial prompt does list circle as a selectable option alongside line and arc, though the source only walks through dedicated procedures for lines, arcs, and the vertex-and-endpoints method specifically, not a separate circle-specific example.
