One of the first thing you might discover about BricsCAD® are selection windows (selection boxes). Clicking and dragging your mouse creates a green or a blue “box”.  These are probably the easiest way to select multiple entities in BricsCAD, but BricsCAD offers a whole lot more options for selecting entities!

Green or Blue?

If you click and drag the mouse left to right a blue window appears. If you move it right to left a green window appears.

Inside Window blue box – only the entities (objects) that are fully inside the box are selected.

Crossing Windowgreen box – everything inside the box, fully or partially, is selected.

Thinking Outside the (selection) box

Selection windows are not just limited to rectangular boxes in BricsCAD. Use the Select command to gain access to additional selection methods.

Using the Window circle, Crossing circle and Outside circle options, you can even create selections using a circular boundary!

Another option, unique to BricsCAD, is the Point selection option. It selects any closed boundaries around a given point.

The Fence selection mode selects all entities that cross the line “fence” drawn.

Plus many more

Not to be forgotten are the Select all entities (Ctrl+a), Previous selection and Last entity in drawing selection modes. Always useful and they all do exactly what they say on the tin.

Selecting in 3D!

If you’re using selection boxes in 3D, hold Ctrl to switch between selecting faces, edges or solids. The HotKey Assistant will guide you through.
