Is there a turorial on how to install a PCB design rules template?
Kicad has no special templates for loading/installing design rules.
However, you can:
start a new project from a project template - the newly created project incorporates all design rule settings from that project template
start a new project from a existing project with kicad main manager–>File–>Save project As. The newly created project also incorporates all design rule settings from the original at project.
or import the design rules from another project were the pcb-constarints are already set to your liking: pcb-editor: File–>board setup–>button “import settings from another board”
In all 3 cases you need a original template/project/board to the copy the DRC constraints.
Is there a way to get KiCAD to automatically adjust the pad size when the hole size is changed?
