Bring Your Own Patterns (or BYOP) is a system that allows subscribers to upload their PDF patterns that they own. This works like any other projector.

All Ditto subscribers will have access to the BYOP feature.

There is no additional cost for annual and monthly subscribers.

Use the Email Us button the bottom left of our website. Choose Product Features as the topic.

You will need to use an A0 or projectable PDF pattern. Only one page is projected, so if you have a traditional, multi-page PDF pattern, you’ll want to merge your tile pages together using a third-party PDF editing software. This will create a projectable file by digitally taping each page of the PDF file together for you.

Make sure that your file does not contain embedded raster images or JPEGs.

Check your pattern to ensure all pattern pieces are in one large area, as opposed to multiple pages, and that your projection area is within our parameters. You can check your projection dimensions under the document properties tab.

The smaller size of the PDF must be 60” or less. For example, it could be 140”x48” or 60”x120” but not 75”x125” or 139”x69”.

Sizing is the same as with other PDF uploads. The sizing is what is provided with the file and can’t be customized.

Using a third-party PDF editing software, select the layers tab and change line thickness to at least 5 pt. and select apply. Then select generate PDF. Occasionally you may have to make this setting a little higher depending upon your projection environment.

Check the instructions for seam allowances as every third-party pattern company may be different. To keep from interfering with the projected line, always cut on the outside of the line.

Your PDF patterns will be in My Pattern Library/My Uploads on the app and website.

You can have 5 patterns at a time in your Library. This space is meant for projection, not data storage.

Uploading a PDF pattern with Ditto is the same as with any other projector. You can’t move the pieces around.

Although you cannot rotate in the workspace, you can do so in a PDF viewer or editor. Prior to uploading the file to your account, rotate the pattern page to the orientation you would like to project and save. When you upload, it should show up the same way.

While you may not see all pieces at once, you can use the splicing tool to move your visible window around the pattern to see more pieces.

You can use a fabric marker, or you can find ¾” circle stickers at most office supply stores.
