Configure snap

You are here: General functions > Configure snap

The snap is a tool for determining the position for working with dynamic functions Closed . You can configure the snap and adapt it to the current situation.

Use Snap Points

Help tool for positioning on end, middle or intersection points of lines.

General snap
	When approaching an end, middle or intersection point, the cursor will be snapped. The current position is displayed. Animation	Snap points are ignored. You can freely move the cursor.	Activate temporarily [Shift] You can activate the snap point function temporarily for a single operation. Press and hold [Shift] When approaching an end, middle or intersection point, the cursor will be snapped. The current position is displayed. Temporarily disable [Alt] You can disable the snap points for a single operation temporarily. Press and hold [Alt] Snap points are ignored. You can freely move the cursor.
When working with polyline, routing systems, pipes and ducts
	When they meet with an existing line, DDS-CAD calculates the intersection so that the polyline is perpendicular to the existing line. Animation	Existing lines are ignored.

Use Snap to Grid

Tool for symmetrical array of objects.

Option is active	Option is not active	See also
DDS-CAD generates a symmetrical grid of horizontal and vertical lines. The intersections snap and hold the cursor.	The grid is turned off. You can freely move the cursor.	Grid Origo - 1 point

		View X-Axis in Grid Horizontal
		Reset Grid
		Visible grid points Select: Format Grid/Coordinate

Use Smart Snaps

Tools for working with connectable objects (e.g. cables, routing systems, pipes, ducts).

	Option is active	Option is not active	Examples
	In case the cursor comes close to a connection point, DDS-CAD will automatically recognize it. You can create the connection.	The snap function is not active. You can define a fix point close to the object.	Fluorescent Lamp Ladder Air Handling Unit

Use Surface Mode

Tool for working on building surfaces or geometric shapes.

	Option is active	Option is not active	See also
	The surface of building areas and geometrical shapes define the mounting height of the object. You can place, for example, an object on an inclined roof. DDS-CAD calculates the correct mounting height.	DDS-CAD ignores the surfaces of building elements and general geometries. The mounting height is related to the coordinate system.

Use Automatic Rotation

Tools for working with dynamical symbols when using the line snap with [Ctrl].

	Option is active	Option is not active	See also
	When approaching a line, the symbol will rotate perpendicular to the line. Animation	When approaching a line, the symbol retains its current rotation.

Ortho mode (Ortho)

Help for the defined direction change for polylines and for subsequent parallel displacement of objects.

When working with polyline, routing systems, pipes and ducts

With an active line, the movable end does not precisely follow the cursor. The direction changes gradually in defined angles. You can create a rectangular course with your mouse, but not reach each desired position.

The moveable end of the line follows the cursor accurately. You can reach any desired position.

Decrease Ortho Angle

Set Ortho Angle Step

Move existing symbol

An object does not accurately follow the mouse cursor. Movements are only possible in defined directions. You can move the object horizontally or vertically, but not reach each desired position.

The object follows the cursor. You can reach any position.
