Guide Line
Guide Line creates a persistent 3D SketchLine reference. Accepted segments can chain continuously, and their endpoints are available to Endpoint OSNAP even when a solid projects behind the line.

Step by step
- Choose Line and pick the first point with OSNAP if required.
- Pick the next endpoint. The accepted endpoint becomes the start of the next segment.
- Hold Shift when you want orthogonal local X/Y/Z acquisition.
- Press Esc to cancel only the unfinished preview while preserving accepted segments.
Continuous chaining
Each accepted endpoint becomes the next segment's start, so you can build a multi-segment guide path without restarting the command.
True 3D orthogonal directions
Shift orthogonal placement works with projected local X/Y/Z axes, including true vertical +Z/-Z segments.
Endpoint snapping
Persisted Guide Line endpoints receive a comfortable, sparse screen-space aperture and can compete with a solid underneath the cursor rather than being masked by it.
Keep in mind
- Use Guide Lines for references. They are not exported as ordinary Plant 3D™ solids.
