Setting a cursor snap angle and using drawing aids

When you draw linear elements (a wall or a line, for example), you can draw either freely or you can restrict the direction in which you draw to a specific angle. You can make this setting on the right in the dialog line.

You can restrict movement to either horizontal/vertical (ortho constraint) or set a cursor snap angle of your choice. The current setting for the system angle is taken into account. For example, if the system angle is set to 30°, then this is interpreted as being horizontal.

Note: If you have set a cursor snap angle, then this will have priority over any point snap settings you have made, as well as any other settings on the shortcut menu. This means that only points in alignment with one of the set cursor snap angles will be snapped.

You can use the following options in the dialog line to restrict cursor movement to a specific direction or angle:

Icon	Function	Use
	No icon pressed in	The line can be drawn at any angle. This is the default setting.
	Enter at right angles	The line can only be drawn at right angles to the current system angle.
	Cursor snap	The line can only be drawn at specific angles.
15.00	Cursor snap angle	Define the cursor snap angle here (only possible when is switched on).
