Using DXF Splitter

Sign in and open a file

A free account is enough to try it. Sign in, then drag a DXF onto the page or use Open a DXF…. There's no upload to wait for — the file is read straight off your disk and never leaves your machine.

After creating an account, check your inbox for a verification link — you'll need to click it before you can sign in.

The free plan covers one nest of up to 100 parts. A Day pass or Pro removes that limit and unlocks layer remapping, the parts report and naming templates — see Plans and pricing, and "Your account" below for redeeming a code or upgrading. Pro alone also adds combined, deduplicated export across several queued nests at once.

Work through several files

Select or drop more than one DXF at once and they queue up rather than replacing each other. A strip above the canvas lists them; the first starts right away while the rest wait their turn.

Each file is split, reviewed and exported exactly as a single file would be — nothing here changes on its own. Click Next file when you're ready to move to the next queued one, or click any still-queued entry in the strip to jump to it directly.

Read the canvas

Drag to pan, scroll to zoom, and use Fit to frame the whole nest again. Hover a part to highlight it; click to select it, and shift-click (or ctrl/cmd-click) to add more parts to the selection.

Check the Parts tab

Every part DXF Splitter found is listed with its size, hole count and any marks it carries. A part flagged unnamed had no name to read from the drawing, and one flagged duplicate name shares a name with another part — both still export fine, just under a name it had to fall back to.

Click the zoom link on a row to jump to that part on the canvas. Select all / Select none work on the whole list. Only selected parts are exported.

Check the Layers tab

Each layer that actually has geometry or text on it is listed with what DXF Splitter read it as — cut, mark, annotation or ignore — and why. Layers declared in the file but never drawn on are folded under a small "declared but empty" line rather than cluttering the list.

The checkbox on a layer hides it on the canvas and in the warnings list; it's a view setting only and has no effect on what's exported.

On Pro, the role dropdown lets you correct a layer DXF Splitter guessed wrong, or remap a customer's layer names onto your own — changing a role re-runs detection, since chaining, containment and naming all depend on which entities count as cut geometry. On Free the roles are shown but locked.

Check the Contents tab

Shows the raw text of the loaded DXF file. Selecting a part on the canvas or in the Parts tab highlights every line belonging to it — its outline, holes, marks and any labels — wherever they fall in the file, since a part's entities are often scattered rather than sitting together.

Click precisely on one entity's own line or arc on the canvas (rather than inside a part's fill) to narrow the highlight to just that entity's text; this doesn't change which parts are selected for export. Clicking a highlighted line back in the Contents tab does the same in reverse, picking out that entity on the canvas.

Check the Settings tab

Units shows Imperial or Metric when the file's own header says so. When it doesn't, set it by hand so measurements read correctly — this doesn't change the geometry, only how it's interpreted.

Join tolerance is the gap size DXF Splitter will bridge when deciding two entities belong to the same profile. Auto (the default) picks a sensible value from the drawing itself; enter your own if parts are joining that shouldn't, or not joining that should, and use Reset to go back to Auto.

Remove outer border tries to detect and drop a surrounding sheet or frame contour before grouping parts, for nests where the border would otherwise be read as a part.

Read the warnings

Anything worth a second look — an open contour, a layer with no clear role, a file with no units — shows up here rather than failing silently. Where a warning points at a place in the drawing, its show link zooms straight to it. Warnings about a layer you've hidden are hidden too, since they're not something you're looking at.

Export

Select the parts you want and click Export. You get a ZIP, built and downloaded entirely in your browser, with one DXF per selected part. On Free, exporting more than 100 parts writes the first 100 and tells you how many were left out; Day pass and Pro have no such limit.

If you're working through a queue of several files, exporting doesn't advance it — use Next file in the strip above the canvas once you're done with this one.

Export several files as one, without duplicates

Opening a single DXF looks just like it always has. The strip above the canvas, with De-dupe and Export and Next file, only appears once a second file is queued alongside it — add one with Open a DXF… or by dropping it in.

De-dupe and Export splits every queued file if it hasn't already, then writes a single ZIP with one copy of each distinct part shape — a part repeated across several files, even rotated or mirrored, is written once instead of once per copy. Before writing anything it tells you how many unique parts and how many duplicates it found, so you see the count rather than having parts disappear silently. Matching only merges parts whose outline and any holes agree closely enough to be the same physical part; anything it isn't confident about is kept as its own file.

This is a Pro feature. The button is there on every plan, but on Free or a Day pass, clicking it tells you it requires a monthly or yearly plan rather than running.
