Mini-CAD: Capturing line ends
If several lines need to be connected to a polygon, the precise positioning of the mouse at the end of the previous line can be difficult. This can be greatly simplified by activating the "Capture line ends" tool in the pop-up window.
After pressing this too, the mouse pointer changes to a square with cross-hairs. If, when pressing or releasing the left mouse button, an existing line end is within the square, the new line end will automatically capture the existing line end.
Depending on the layer selected as the selection layer using the "Layers" icon preferences, the end points of lines on different layers can also be snapped to: Drawing is always carried out on the currently active drawing layer (also see “Mini-CAD System preferences: Layer preferences").
