Draft Snap
Description
Snäppa innebär att din nästa 3d punkt "klistras" på en existerande punkt.
Another way of selecting points is by 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:Draft ToggleSnap.svg Toggle snap button, located in the snap toolbar: View → Toolbars → Draft Snap.
Note: using many snapping methods at the same time can be problematic; in this case, try activating only one snapping method.
Snäppning i Skissmodulen har två lägen: ett aktivt läge och ett passivt läge.
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.
- File:Draft ToggleSnap.svg Toggle snap: toggles object snapping globally on or off.
- File:Snap Endpoint.svg Endpoint: snaps to the endpoints of line, arc and spline segments.
- File:Snap Midpoint.svg Midpoint: snaps to the middle point of line and arc segments.
- File:Snap Center.svg Center: snaps to the center point of arcs and circles.
- File:Snap Angle.svg Angle: snaps to the special cardinal points of circles and arcs, at 45° and 90°.
- File:Snap Intersection.svg Intersection: snaps to the intersection of two line or arc segments. Hover the mouse over the two desired objects to activate their intersection snaps.
- File:Snap Perpendicular.svg Perpendicular: on line and arc segments, snaps perpendicularly to the latest point.
- File:Snap Extension.svg 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.
- File:Snap Parallel.svg Parallel: snaps on an imaginary line parallel to a line segment. Hover the mouse over the desired object to activate its parallel snap.
- File:Snap Special.svg Special: snaps on special points defined by the object. introduced in version 0.17
- File:Snap Near.svg Near: snaps to the closest point or edge on the nearest object.
- File:Snap Ortho.svg Ortho: snaps on imaginary lines that cross the last point, and extend at 0°, 45° and 90°.
- File:Snap Grid.svg Grid: snaps to the intersections of the grid lines, if the grid is visible.
- File:Snap WorkingPlane.svg Working plane: always places the snapped point on the current working plane, even if you snap to a point outside that working plane.
- File:Snap Dimensions.svg Dimensions: shows temporary X and Y dimensions while snapping.
Toggle grid: toggles the visibility of the grid on or off.
Advanced snapping
- 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 Shift or pressing X, Y or Z while drawing.
- Press Q 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 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
Options
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.
