Snapping is available with most [[Draft_Workbench|Draft]] and [[Arch_Workbench|Arch]] commands.
However, when these parameters need to be precise, it is possible to enter the exact [[Draft Coordinates]] in the dialog for the tool.


[[Image:Draft_Snap_Endpoint_example.png]]
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 Workbench|Draft]] and [[Arch Workbench]] tools, and can be enabled and disabled globally with the {{Button|[[Image:Snap_Lock.svg|16px]] [[Draft ToggleSnap|Draft ToggleSnap]]}} button, located in the snap toolbar, which can be made active with the menu {{MenuCommand|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, try using only one snapping method at the time.

Snäppning i Skissmodulen har två lägen: ett aktivt läge och ett passivt läge.


These tools are available in the Draft snap toolbar and in the [[Draft_snap_widget|Draft snap widget]].
===Passivt läge===
Du är automatiskt i passivt läge när du ritar.
Om din musmarkör i passivt läge svävar över ett existerand objekt, så kommer din punkt att snäppas till den närmaste punkten på objektet. En öppen cirkelsymbol syns.

Description

Snäppa innebär att din nästa 3d punkt "klistras" på en existerande punkt.

Snapping is available with most Draft and Arch commands.

Snap tools

These tools are available in the Draft snap toolbar and in the Draft snap widget.

Note that circular edges do not have to be full circles.

  • Snap lock: enables or disables snapping globally.
  • Snap angle: snaps to the special cardinal points on circular edges, at multiples of 30° and 45°.
  • Snap extension: snaps to an imaginary line that extends beyond the endpoints of straight edges.
  • Snap parallel: snaps to an imaginary line parallel to straight edges.
  • Snap special: snaps to special points defined by the object.
  • Snap near: snaps to the nearest point on faces and edges.
  • Snap ortho: snaps to imaginary lines that cross the previous point at multiples of 45°.
  • Snap grid: snaps to the intersections of grid lines.

Advanced snapping

  • Additional snap points can be obtained by combining two snap options. For example combining Draft Snap Ortho and Draft Snap Extension will give you a snap point at the intersection of their imaginary lines.
  • Snapping can be combined with constraining.
  • Press Q to insert a "hold point" at the current location of the cursor. You can snap to the orthogonal axes of hold points, and to the intersections of these axes. If the Draft Snap Midpoint option is active, you can also snap to the midpoint between two hold points.
  • Press ` one or more times to snap to an object that is obscured by other geometry. This is called "snap cycling". Note that you must move the cursor by a small amount in the 3D view after pressing the key.

Snap cycling 1: The red rectangle was created first therefore it has snap priority. Without snap cycling you cannot snap to the green rectangle where it is overlapped by the red rectangle.

Snap cycling 2: After using the snap cycle key once the green rectangle receives snap priority. Snapping to the midpoint of the overlapped green edge is now possible.

Notes

  • Multiple snap options can be active at the same time, but it is advisable to only activate the snap options you really need. Activating too many can slow things down.
  • It is not a good idea to have Draft Snap Near permanently active as it takes precedence over many other snap options.

Preferences

Aktivt läge

För att växla till aktivt läge, håll ned CTRL medan du ritar. I aktivt läge, så visas antingen en stängd cirkel eller en öppen eller stängd kvadrat, beroende på snäpptyp. I alla verktyg som stöder snäppning, är följande snäpp platser tillgängliga:

  • Linjernas ändpunkt
  • Linjernas mittpunkt
  • Cirklarnas och cirkelbågarnas centrum
  • Cirklarnas och cirkelbågarnas kvadrantpunkter
  • Cirkelbågarnas ändpunkter
  • Vid begränsning (SKIFT), vertikalt eller horisontellt uppriktade punkter på linjer
  • Skärningspunkter mellan segment

I verktyg som stöder både snäppning och begränsning, så kan kombinationen av båda (SKIFT+CTRL) utöka snäppningsmöjligheterna.
