How to Import a DXF Pattern into CLO3D

CLO3D imports DXF in the apparel conventions, so a DXF AAMA file is the ideal input. It carries the piece outlines, internal lines, grainlines and notches that CLO3D can interpret, rather than a flat drawing with no structure.

Before importing, confirm the unit system the file was authored in. A pattern drafted in millimeters that is imported as inches will appear at the wrong scale, and fixing scale after the fact is more error-prone than setting it correctly up front.

When you open the DXF import dialog, CLO3D asks how to interpret the file's units. Choose the unit that matches how the pattern was created. If you are unsure, import once, measure a known dimension against the pattern's stated size, and adjust if it is off.

Getting units right at this stage is non-negotiable. Every downstream step, from sewing to draping to fit assessment, assumes the geometry is at true scale.

1. 1.In CLO3D, open the file menu and choose to import a DXF pattern file.
2. 2.In the dialog, set the unit to match the pattern's authored units.
3. 3.Choose whether to flatten or keep internal lines and notches, keeping them where the design needs them.
4. 4.Confirm the import and review the pieces placed in the 2D pattern window.
5. 5.Verify a known measurement on one piece before going further.

After import, inspect the pieces in the 2D window. Check that each is a closed shape, that grainlines point correctly, and that notches landed where expected. Imported DXFs occasionally contain stray construction lines or duplicate points that are worth removing before you sew.

If curves look faceted, the original export may have approximated them with short segments. CLO3D can work with these, but smoother input produces cleaner seams and easier editing later.

Move the 2D pieces into position around the avatar in the 3D window so left and right, front and back, sit roughly where they belong. This arrangement helps the simulation drape pieces sensibly rather than tangling them.

Then define the sewing relationships: which edge sews to which edge. CLO3D uses these seam definitions to stitch the flat pieces into a closed garment. Accurate seams are what let the simulation produce a believable fit rather than a collapsed mess.

• Position pieces around the avatar before simulating
• Match seam lengths and directions when defining stitches
• Use notches as alignment cues for long curved seams
• Simulate, then refine seam assignments where the garment misbehaves

With pieces sewn, run the simulation and let the garment settle on the avatar. CLO3D then offers fit visualization such as tension and pressure maps that reveal where a garment strains or hangs loose, turning a flat pattern into actionable fit feedback.

This is the payoff of the import: a 2D pattern you can evaluate in 3D before cutting cloth. Iterate on the pattern, re-import or edit, and watch the fit change on screen.

A smooth CLO3D import starts with a well-structured DXF. Minerva Patterns delivers every pattern as DXF AAMA, PLT and PDF, so the DXF AAMA file is ready for CLO3D while the PLT and PDF cover plotting and print output.

You can browse the catalog, download the DXF AAMA file, and bring a professionally drafted pattern straight into your 3D workflow without redrawing anything by hand.
