1. Docker Snap
2. Docker Snapshot Volume

I disabled snap.docker.dockerd.service (systemctl disable snap.docker.dockerd.service) as you did and it works! Thanks for your help! Thanks for your help! Then, any docker-related commands you use will be safely executed in this new environment. Note: The use of the setupremotedocker key is reserved for configs in which your primary executor is a docker container. If your executor is machine (and you want to use docker commands in your config) you do not need to use the setupremotedocker key.

Description

The Draft Workbench tools allow you to pick points and distances by clicking on the 3D view with the pointer, or by entering Draft Coordinates in the task panel of the tool.

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 button, located in the snap toolbar: View → Toolbars → Draft Snap.

Line snapping perpendicularly to another line

Draft Snap toolbar

• Toggle snap: toggles object snapping globally on or off.
• Endpoint: snaps to the endpoints of line, arc and spline segments.
• Midpoint: snaps to the middle point of line and arc segments.
• Center: snaps to the center point of arcs and circles.
• Angle: snaps to the special cardinal points of circles and arcs, at multiples of 30° and 45°.
• Intersection: snaps to the intersection of two line or arc segments. Hover the mouse over the two desired objects to activate their intersection snaps.
• Perpendicular: on line and arc segments, snaps perpendicularly to the latest point.
• 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.
• Special: snaps on special points defined by the object. introduced in version 0.17
• Near: snaps to the closest point or edge on the nearest object.
• Ortho: snaps on imaginary lines that cross the last point, and extend at 0°, 45° and 90°.
• Grid: snaps to the intersections of the grid lines, if the grid is visible.
• Working plane: always places the snapped point on the current working plane, even if you snap to a point outside that working plane.
• 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

Preferences

• The maximum distance at which a point is considered a snapping point can be changed on-the-fly by pressing [ (increase) or ] (decrease) keys. This setting is stored: Tools → Edit parameters... → BaseApp → Preferences → Mod → Draft → snapRange.
• The mentioned keys can be customized in the Draft Preferences: Edit → Preferences... → Draft → User interface settings → In-Command Shortcuts.

Notes

Docker Snap

• It is advisable to only activate the snap methods you really need. Activating too many can slow things down.
• It is not a good idea to have Near snap permanently active.
