Import best practices for standard formats

Best practices for an AAMA/ASTM (.dxf) format include seam allowance, marked as internal lines, correct scale, internal marks for darts, pocket placements, and grading if required.

To convert internal lines to seam allowance:

From the Toolbox, select Seam > Convert Internal to Seam.
Apply to each internal line.
Alternatively, select all pieces and then, on the menu go to Tools > Seam > Convert Sew Internals to Seam
Make sew lines the active lines: select all pieces and then switch from cut line to sew line.

To Make pieces Symmetrical:

From the Toolbox, select Half Symmetry > Set Half and follow tool instructions on the status bar.

To Turn internal lines into a Dart:

From the Toolbox, select Darts & Pleats > Dart and select in a Clockwise direction each dart leg, then select the dart tip.
Select the old internal lines marks for dart and press Delete.

Troubleshooting

If the pieces scale is wrong: Repeat the import and change Working units and/or Scale Factor.
No pieces are imported: Repeat the import, and try a different File Format.
No pieces are imported: Repeat the import, but select BOX, this will import everything as one drawing from which you will be able to build the pieces.

Guidelines for AAMA/ASTM Import

Prior to the import, adjust layers assignment if needed.
- You can do this in the Import dialog >Setup > Layers Table.... to get correct import of certain objects of various types.
Sometimes, the import needs a RUL file in addition to DXF .Sometimes, the grading is embedded in the DXF file itself.
If a needed rul file is missing, the pattern will be loaded without grading.
The name of the RUL file should be readable in the computer that receives a DXF; i.e., if the computer doesn't have Chinese, it won't open the RUL that has Chinese within.
