Another way of selecting points is by snapping. Snapping means "gluing" your next point onto an existing point or feature of another object.
Note: using many snapping methods at the same time can be problematic; in this case, try activating only one snapping method.
Line snapping perpendicularly to another line
Available snap locations
- Near: snaps to the closest point or edge on the nearest object.
- Extension: snaps on an imaginary line that extends beyond the endpoints of line segments. Hover the mouse over the desired object to activate its extension snap.
- Parallel: snaps on an imaginary line parallel to a line segment. Hover the mouse over the desired object to activate its parallel snap.
- Grid: snaps to the intersections of the grid lines, if the grid is visible.
- Endpoint: snaps to the endpoints of line, arc and spline segments.
- Midpoint: snaps to the middle point of line and arc segments.
- Perpendicular: on line and arc segments, snaps perpendicularly to the latest point.
- Angle: snaps to the special cardinal points of circles and arcs, at 45° and 90°.
- Center: snaps to the center point of arcs and circles.
- Ortho: snaps on imaginary lines that cross the last point, and extend at 0°, 45° and 90°.
- Intersection: snaps to the intersection of two line or arc segments. Hover the mouse over the two desired objects to activate their intersection snaps.
- Special: snaps on special points defined by the object. introduced in version 0.17
- Dimensions: shows temporary X and Y dimensions while snapping.
- Working plane: always places the snapped point on the current working plane, even if you snap to a point outside that working plane.
- Additional snap locations can be obtained by combining two snapping methods, such as Draft Ortho and Draft Extension, that will give you a snap point at the intersection of their imaginary lines.
- Other snap locations can be obtained by using Draft Constrains, that is, by holding or pressing , or while drawing.
- Press Draft Midpoint snapping is enabled, you will also be able to snap at the mid distance between any two hold points. introduced in version 0.17 while drawing to insert a "hold point" at the current location of the cursor. You will then be able to snap orthogonally to these hold points, and at the intersections of their orthogonal axes. If
- Toggle grid: turns the working plane grid on and off.
- Lock: turns snapping on and off globally.
- The maximum distance at which a point is considered a snapping point is specified in the Draft Preferences, and can also be changed on-the-fly by pressing (increase) or (decrease) keys.
- Pressing while drawing locks the current angle of the line segment being drawn.
