Learn/Drafting/2D Sketch Editor
Selection Modes
At a glance
- Click to select — or select the whole group if the entity is grouped
- Drag left-to-right: window selection (fully enclosed only)
- Drag right-to-left: crossing selection (anything the box touches)
- Space: chain-select — flood fill all connected lines and arcs
- Cmd/Ctrl+A: select everything in the sketch
- Shift+Click: deselect individual entities
Selection in the sketch editor works the way AutoCAD veterans expect, with a few additions for parametric work. Click an entity to select it — clicking it again deselects, Shift+Click removes it from a larger selection, and clicking empty space clears everything. If the entity belongs to a group, the whole group selects as one.
Window vs. crossing
Drag a box left-to-right for a window selection (blue) — only entities completely inside the box are selected. Drag right-to-left for a crossing selection (green) — anything the box so much as touches is included. Crossing tests against the actual curve, not a bounding box, so a skinny box across one edge of a part grabs just that edge. Hold Shift while box-selecting to add to the existing selection instead of replacing it.
Chain select
Select any line or arc and press Space: the selection flood-fills outward through every connected line and arc until the chain ends or closes. This is the fastest way to grab a whole profile, and it's how you feed the chain-based modify tools — Offset takes the chain as its input, and Fillet switches to fillet-every-corner mode when it's handed a closed chain. With several entities selected, Space chains from each one, so disconnected profiles select in one press.
Cmd/Ctrl+A selects everything, Esc clears, and Delete removes the selection — constraints
and dimensions attached to deleted entities are cleaned up automatically.
