Different Types of Cut
- Decide whether each part should be a drawn line (vector score), a filled area (raster engrave), or cut through - for overal outline or internal cut-outs.
- Set a stroke outline of a different colour for each, but no fill. The laser cutter software will be set later to apply a different treatment for each colour.
Text
- To allow lettering to be cut through material without parts falling out, download & install a stencil font, such as Awery.
- Text can be typed in, re-sized & moved.
- Once a piece of text is converted to a path (by Path > Object to Path), it’s no longer editable as text characters. Save file with different names before & after converting to path.
- Select a different stroke colour for a scored line vs filled ‘raster engrave’.
