Object snaps (OSNAP)
Object snaps acquire exact geometric references such as endpoints, midpoints, centres and quadrants. They are used throughout placement, sketches, ports and transform-related picking.
- Where to find it
- Designer viewport > OSNAP controls/status
- When to use it
- Placing or sketching relative to existing geometry instead of approximating by eye

Step by step
- Enable the snap types needed for the current task.
- Move the cursor near the desired reference until the snap marker/label appears.
- Click only after the intended snap type is visibly acquired.
- Orbit or zoom if multiple candidates overlap in screen space.
Common references
Endpoint and Midpoint are useful for edges and Guide Lines. Centre and Quadrant are important for circular/cylindrical geometry. Cap centres are resolved from the hovered cylinder/cone cap rather than from unrelated hidden geometry.
Guide Line endpoints
Persisted Guide Line endpoints are lightweight overlay snap candidates. They can still be acquired when a large Boolean solid sits behind the line in screen space.
Focused aperture
The resolver favors geometry that is actually under the cursor so hidden or distant mesh detail does not steal snaps. Sparse Guide Line endpoints are allowed to compete when they are genuinely closer to the cursor.
Keep in mind
- When a snap feels hard to acquire, zoom in slightly before increasing scene complexity. The snap aperture is screen-space based.
