Description

Draft Workbench tools allow you to pick points, distances, radiuses, and angles graphically by clicking on the 3D view with the pointer.

However, when these parameters need to be precise, it is possible to enter the exact Draft Coordinates in the dialog for the tool.

Another way of selecting more precise points is by using snapping. Snapping means "gluing" your next point onto an existing point or feature of another object.

Snapping is available with most Draft and Arch Workbench tools, and can be enabled and disabled globally with the File:Snap Lock.svg Draft ToggleSnap button, located in the snap toolbar, which can be made active with the menu View → Toolbars → Draft Snap. Each snap method can be enabled or disabled individually by clicking the corresponding button on the toolbar.

While using many snapping methods at the same time can be useful to draw your objects in the desired positions, it can also be problematic if your cursor attaches constantly to the wrong points. If this is the case, and you are having problems correctly positioning your points, try using only one snapping method at the time.

Available snap locations

Options

  • File:Snap Lock.png Lock: turns snapping on/off globally
  • Certain additional snap locations can be obtained by combining 2 snap locations, such as ortho + extension, that will give you a snap point at the intersection of their imaginary lines.
  • Other, more complex snap locations can also be obtained by using constraining (by pressing SHIFT or X or Y or Z while drawing).
  • Pressing L while drawing locks the current angle of the line segment being drawn.
  • The maximum distance at which a point is snapped a snap location is specified in the preferences, and can also be changed on-the-fly by pressing [ or ] keys.
  • Pressing Q while drawing inserts a hold point at the current location of the mouse cursor. You will then be able to snap orthogonally to those hold points, and at the intersections of their orthogonal axes. If 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
