Silhouette Cameo applique for machine embroidery: SVG or DXF, scale and cut

Silhouette Studio is the one cutter software where the file format you download depends on how much you paid for the software. The free edition opens DXF. SVG needs Designer Edition. Both work for applique, but they behave differently at import, and the difference is exactly the thing that decides whether the piece lands under the satin.

This guide covers the edition question, the 1:1 check that you must do with DXF and should do with SVG, blade choice for fabric on a Cameo or Portrait, and the fusing step that makes fabric cut cleanly on a Silhouette mat. The stitch-side sequence (placement run, tack-down, satin) is the same as on any machine; it is explained in placement, tack-down and satin.

Basic versus Designer Edition

Silhouette's own list of what each edition opens (Silhouette support: File types and features) breaks down like this for cut files:

| Edition | Price on silhouetteamerica.com | Opens | Notes for applique | | --- | --- | --- | --- | | Basic | Free | STUDIO, GSD/GST, DXF, plus JPG, PNG, BMP, GIF, TIF | Use our DXF; set the size manually | | Designer Edition | 49.99 USD | Adds SVG and PDF | Use our SVG; imports at the mm size in the file | | Designer Edition Plus | 74.99 USD | Adds embroidery formats PES, DST, EXP, JEF, XXX | Can open the stitch file itself to trace, but that is a manual job | | Business Edition | 99.99 USD | Adds AI, EPS, CDR; exports SVG and PDF | Only edition that can save SVG back out |

Silhouette's product page says it directly: "To open SVG files you will need Silhouette Studio Designer Edition or above" (Silhouette Studio). Prices are the list prices on that page at the time of writing and change during sales.

The practical recommendation: if you already own Designer Edition, use SVG. If you use the free Basic Edition and cut applique a couple of times a year, use DXF and do the size check below every time. If you cut applique every week, the 49.99 upgrade pays for itself in skipped re-cuts.

The 1:1 import check

Two facts from Silhouette's own troubleshooting page (Silhouette support: Importing and exporting troubleshooting) decide how you do this:

• "SVG files need to be at the default rate of 72 DPI to retain their size." That applies to unit-less SVGs. Our SVG declares its width and height in millimetres, and one user unit is one millimetre, so Silhouette reads the physical size rather than guessing at 72 per inch. Download the "Silhouette" target, which keeps mm (the "Cricut" target writes inches, which also imports correctly but there is no reason to use it here).
• "DXF files are not formatted such that they retain size information when they are imported into other programs." Our DXF is an R12 file in millimetres with the units flag set, and Silhouette Studio usually imports it at true size, but Silhouette's advice stands: check, and resize by typing if needed.

The check is the same for both:

1. In the studio, note the cut piece size shown on the download panel. It is the placement size plus twice the allowance: a 100 mm heart with a 0.6 mm allowance is 101.2 mm wide.
2. Import the file into Silhouette Studio. Select the piece (all rings together, so a letter's counter stays with it) and open the Transform panel, Scale tab. Set units to mm.
3. Compare the width to the studio's number. Within 0.1 mm: proceed. Anything else: type the correct width with "lock aspect" on, then check the height matches too.
4. Print the template at 100 percent and measure its 100 mm bar with a ruler. Cut one test piece and lay it on the template: the fabric edge should sit on the solid cut line, a hair outside the dashed placement line.

If a DXF comes in at 75 percent or 133 percent, that is the 72 versus 96 units-per-inch mismatch and the typed width fixes it. If it comes in at some other random ratio, the file was opened and re-saved in another program on the way; download it again.

Do not use Silhouette Studio's Offset tool on the piece. The allowance is already in the path; an offset adds a second one, and a 0.6 mm allowance that becomes 1.2 mm will show fabric outside the satin's outer rail. The reasoning behind the allowance the tool picks, and the two failure modes at either end, are in choosing a cut allowance.

Blade choice for fabric

Silhouette's current blade lineup (Silhouette blades) has one blade sold for fabric: the Rotary Blade, described as one that "glides through fabric without tearing", listed at 34.99 USD and compatible with the CAMEO, Portrait and Curio families. Silhouette also sold a blue "Fabric Blade" for older Cameo models, which is a standard blade with a stiffer housing; if you have one, it works on fused fabric, but check your machine's manual for which blades your model accepts.

| Blade | Fabric state | Result on fused quilting cotton | Result at thin points | | --- | --- | --- | --- | | Rotary Blade | Fused or unfused | Clean | Clean, small radius on tight corners | | AutoBlade or manual ratchet blade | Must be fused to a paper-backed adhesive | Acceptable, some fuzz on the bias | Fraying, occasional tear-out | | Kraft or deep-cut blade | Fused, heavy fabrics such as felt or canvas | Clean on thick material | Blunt corners |

The rotary wheel needs a run-in and a run-out, so keep the design at least 10 mm from the fabric edge and the fabric fully inside the mat's adhesive area. A cutting mat with fresh tack matters more for fabric than for cardstock; a tired mat lets the fabric creep ahead of the blade on curves and the piece comes out oval.

For blade depth: on machines with the AutoBlade, pick the fabric material preset that names your fabric and let the machine set it. On manual blades, common practice is to start one step deeper than your cardstock setting and test on a scrap. Check your machine's manual for the numbered scale; the numbers are not comparable between blade types.

Stabilised fabric: fuse first, then cut

Every Silhouette blade, including the rotary, cuts better when the fabric cannot stretch. For applique you are going to fuse the piece to the garment anyway, so do it before cutting rather than after:

1. Iron a paper-backed sewable fusible web to the wrong side of the fabric while it is still a rectangle. HeatnBond Lite is the common choice; its maker describes it as "paper backed, iron-on, sewable" and says pieces bonded with it "must be sewn for permanent bond", which is what a satin border does (Therm O Web: HeatnBond Lite). Medium heat, no steam, 2 to 4 seconds. Let it cool.
2. Put the fabric on the mat paper side down. The paper releases from the mat cleanly and protects the adhesive. Mirror the design in Silhouette Studio if it has letters or an asymmetric shape, or it will come out reversed.
3. Cut. Peel the piece and its paper off together.
4. Peel the paper only when you place the piece on the placement run at the embroidery machine.

Do not use the no-sew grade of fusible web (HeatnBond UltraHold and similar). It is thicker and gums the needle under a satin. For felt, no fusible is needed; a fresh mat and the rotary blade cut it cleanly, and a light mist of temporary spray adhesive on the back handles placement. More on which fabrics behave under a satin, and which stabiliser goes in the hoop, in fabric and stabiliser.

Multi-piece designs and letters

The SVG lays out every piece exactly where it stitches, on one sheet with a 5 mm margin, each piece as its own compound path with an id of piece-1, piece-2 and so on. In Silhouette Studio that arrives as a group. Ungroup it once to move pieces onto different fabrics, but do not release the compound path of an individual piece: the counter of an A or a B is an inner ring of the same path, held as a hole by the even-odd fill rule. Release it and the counter becomes a separate solid shape that cuts as a disc on top of a solid letter.

The DXF has the same rings on a single layer named CUT, one polyline per ring. Silhouette Studio opens them as separate lines; select the outer ring and its counters together and use Make Compound Path before cutting, so the cut order and the fill preview make sense. Letters under 25 mm cap height are flagged in the studio because the satin has nowhere to go inside the counter; applique letters and monograms explains the limits.

Sequence at the embroidery machine

The cut file matches the first colour block of the embroidery file, so the order is fixed:

1. Cut the fabric on the solid line of the template.
2. Hoop the garment with stabiliser and sew colour block one: the placement run, 2.5 mm running stitch on the outline.
3. Peel the paper, centre the piece so an even sliver of fabric shows outside the stitched line all round, press it down. With spray adhesive and two alignment marks the predicted placement error is 0.3 mm; without, 0.5 mm; rushing, 0.9 mm.
4. Sew colour block two: the tack-down, 1.2 mm inside the outline.
5. Sew colour block three: the satin, 3 to 5 mm wide, outer rail pushed out 0.25 mm on woven fabric for pull-in.

The difference between careful and rough placement is the biggest single lever you have. On a 100 mm design with a 4 mm satin on woven fabric, the predicted clean rate is about 99 percent with careful placement and about 74 percent with rough placement; how that number is built is in stitch-out prediction.

Silhouette-specific problems

| Symptom | Cause | Fix | | --- | --- | --- | | SVG will not open | Basic Edition | Use the DXF, or upgrade to Designer Edition | | DXF opens at the wrong size | DXF does not carry size into Silhouette Studio | Type the width from the studio's download panel, aspect locked | | Piece is twice the allowance too big | Offset applied in Silhouette Studio | Remove the offset; the path already includes it | | Letter cuts as a solid block | Compound path released | Undo, or select rings and Make Compound Path | | Piece reversed | Cut paper side down without mirroring | Mirror in Silhouette Studio before cutting | | Fuzzy edge, torn points | Standard blade on unfused fabric | Fuse first; use the Rotary Blade | | Oval piece from a round shape | Fabric crept on a tired mat | Fresh mat or re-tack; brayer the fabric down |
