How to Create Regions

Quick answer: REGION converts a closed entity into a solid entity. It works on polylines, polygons, circles, ellipses, closed splines, and donuts. In a wireframe visual style there’s typically no visible change, but in a rendered style, regions display with a solid fill.

What Can Become a Region

Closed entities only: polylines, polygons, circles, ellipses, closed splines, and donuts.

What Changes Visually

In a wireframe visual style, converting an entity to a region usually looks no different. However, if the original entity had a width or lineweight, that information is lost in the conversion, worth checking before you convert something you need to keep that detail on. In rendered visual styles, region entities display with a solid fill.

Creating Regions: General Procedure

1. Launch REGION. You’re prompted to select entities or boundaries.
2. Select one or more entities; the running count of entities selected displays, and you’re prompted to select more.
3. Select more, or press Enter to stop.
4. BricsCAD reports how many regions were created.

Frequently Asked Questions

What happens to a polyline’s width when I convert it to a region? It’s lost. Regions don’t retain width or lineweight information from the original entity.

Can I convert an open polyline into a region? No, only closed entities qualify: polylines, polygons, circles, ellipses, closed splines, and donuts.

Will converting something to a region change how it looks in my current drawing? Usually not in a wireframe visual style. In a rendered style, though, it’ll display with a solid fill.

Can I select and convert several entities into regions at once? Yes, keep selecting entities when prompted, then press Enter to finish; BricsCAD reports how many regions it created from your selection.
