Table of contents
Enabled by default, snaps are specific points on markup objects, except for freehand shapes, drawings, or model geometry that behave like magnets. Snaps enable you to connect a markup object to another markup object or to geometry on a 2D sheet.
Design Review displays snaps as you move the mouse pointer over a markup object, drawing, or model geometry. Snaps are located at key points and along the contour of the markup or geometry. The icon indicating a key snap point is red with a white center. 
The icon indicating snap points along the contour between key points is solid red. 
To disable snapping markups to 2D objects
- Click tab
expand the panel. - Uncheck .
Repeat these steps to re-enable snapping markups to 2D objects.
Almost all types of markup can be snapped to the sheet or model content as well as to other markup, with these exceptions: callouts with revision clouds, freehand markups, and custom symbols. However, these markup exceptions can be snapped to by other markup.
- Drag one markup object away from another.
Snapping Priority
As a markup is drawn or dragged near an object, several snap points may be near each other. In this case, Design Review displays the snaps according to the following priority:
- Intersection
- Endpoint, corner, midpoint, or center
- Geometry
For example, if is enabled and you draw a Line shape toward the intersection of two lines, the shape would snap to the intersection of the lines rather than to the midpoint of one of the lines. Where snap settings have the same priority, the snap target that is closer to the mouse pointer is chosen.
