Object snap makes it easier to design when placing lines, members, and surfaces. In addition to nodes, you can use various snap points on objects.
By default, nodes, centers, and line grid points are activated as snap points. If you place a new line, for example, and move the mouse pointer near an object, the associated symbols appear there. They are described in the table below.
You can use the check boxes in the 'Options' dialog section to control which snap points are active:
| Object | Snap points |
|---|---|
| Node | Free nodes and nodes of lines |
| Center and focal points | If you move the mouse pointer near the center of a line, the focal point of a curve, or the centroid of a surface or solid, it snaps there. |
| Intersections | Intersection points of two lines that do not have a common node |
| Perpendicular | Perpendicular connection to a line |
| Extension | Connection to the straight line of a line that has been preselected (briefly touched with the mouse pointer) |
| Parallel | Placing a parallel line: After placing the start node, move the mouse pointer over a reference line. As soon as the mouse pointer approaches a possible end node of the new line so that it is parallel to the reference, the parallel symbol appears on the lines. |
| Tangent | Tangent point of a line on a circular arc |
| Circle quadrants | Division points of a circle in quarter points |
| Divisions | Division points of lines: If you move the mouse pointer over a line, it snaps at the defined divisions 'n'. The division information appears at the mouse pointer as a fraction. |
| Distance | Division points of lines in absolute or relative distance: If you move the mouse pointer over a line, it snaps at the defined distances 'd' from the line start and line end. |
| Only snappable points | Placing nodes only on already defined objects, not arbitrarily in the work plane |
| Guide lines | Intersections of two guide lines |
| Background layers | Intersections of two lines of background layers |
| Building grid | Intersections of two lines of a building grid |
| Surface thickness points | Points for surface thicknesses near the line definition nodes (not in wireframe model display) |
The options for the 'Contour Cross-Section Points' offer snap possibilities for points on the rendered profile, such as corners, edges, or corner-related distances on the cross-section edges. The snap points appear near the line definition nodes.
CAD Toolbar
In the CAD toolbar below the tables, you can not only switch the object snap on and off, but also specifically toggle individual snap functions.
The buttons have the following functions:
|
Switches the snap function for grid points on and off |
|
Switches the object snap on and off |
|
Snap to free nodes and nodes of lines |
|
Snap to center and focal points |
|
Snap to intersections |
|
Snap to perpendicular points |
|
Snap to extensions |
|
Snap to parallel lines |
|
Snap to tangents |
|
Snap to circle quadrants |
|
Snap to division points of lines |
|
Snap to points of lines with absolute distance |
|
Snap to points of lines with relative distance |
|
Snap only to snappable points |
|
Snap to intersections of a building grid |
|
Snap to intersections of guide lines |
|
Snap to intersections of background layers |
|
Snap to surface thickness points |
