(crosshairs). Switches between free angle and 45 degree mode for placement of new tracks, zones, graphical shapes, dimensions, and other objects. You can also toggle between free angle and 45 degree mode using and filled zones that form the copper connections between pads in each net, and various graphic shapes defining the board edge, silkscreen markings, and any other desired information. KiCad normally global adjustment of the clearance (positive or negative) between the copper shapes and solder mask / solder paste shapes of pads on the board. These values will be added to any clearance overrides set

(crosshairs). Switches between free angle and 45 degree mode for placement of new tracks, zones, graphical shapes, dimensions, and other objects. You can also toggle between free angle and 45 degree mode using segments In some situations, KiCad must use a series of straight line segments to approximate round shapes such as those of arcs and circles. This setting controls the maximum error allowed by this approximation: circle. Setting this to a lower number than the default value of 0.005mm will result in smoother shapes, but can be very slow on larger boards. The default value typically results in arc approximation

Tools for making shapes Arranging Shapes Editing shapes Working together with other programs Snapping Animation with Krita Workflow Introduction on paint layers. They describe shapes, like rectangles, circles and straight lines, but also freehand paths. These shapes then get used by the Brush engines to make shapes and drawing effects. Vector Tools to edit vectors. Interestingly enough, all paint tools except the freehand brush allow you to draw shapes on the vector layers. The resulting object won’t use the brush preset for outline unlike the ones

Line thickness, text size, and text appearance can be configured for

This is a special type vector shapes with a magnetic influence on your brush strokes. You can use them as rulers, including with shapes other than just straight. Krita’s vanishing point resolution or upres your image. So for instance, if you were initially working at 72 PPI to block in large shapes and colors, images, etc… And now you want to really get in and do some detail work at 300 or 400
