*Note- SCAL4 pro used.
1- Open SCAL4.
2- Firstly you need to import your pattern file. I recommend an SVG file. if the pattern is not SVG. trace it and convert to a cuttable file.
3- Select a pattern. A background cuttable file works really well.
4- Resize your pattern .
5- Select the text icon and choose your font. Type your text. (or shape) I am using Luducudu font from fontbundles.net.
6- Place the letter over the pattern file. make sure it fits completely in.
7- Select the letter(shape) and right click > appearance > shadow layer.
8- Add and inset shadow and approx 0.15 inch in size. click OK.
9- Select the inset part of the letter and the pattern.
10- Go to Path > intersection.
11- everything will appear to disappear apart from the letter. Do not worry the next steps will fix everything.
12- Select everything on the design area, then go to object > merge.
13- Your letter now has a cuttable pattern in it.
14- If you go to the preview screen you can see the cuttable pattern.
