01What Xyrek does
Xyrek turns a 3D body into a dimensioned 2D drawing. Upload a STEP or STL file and you get all six orthographic faces plus an isometric — solid visible edges, dashed hidden edges, and measurements placed automatically: overall sizes, hole and boss diameters with leaders, hole locations from a datum, and feature steps.
Everything is downloadable as a multi-page PDF (one detailed sketch per face, the 3D view last), SVG per view, and DXF per view that imports back into CAD as a sketch. All output is in millimetres.
02Quick start
- Export your part as STEP from your CAD package.
- Drop the file on the Xyrek sheet (or click the sheet to browse).
- Review the views, click away any measurement you don't want, set a sheet title.
- Download the PDF, or DXF/SVG per view, or everything as one zip.
No part handy? The test plate button on the main sheet runs a sample 80×50 plate with two holes and a boss through the whole pipeline.
03Tutorial — Fusion 360 round trip
The full loop: model in Fusion 360, generate the drawing in Xyrek, pull the drawing back into Fusion 360 as sketch geometry.
- Export. In Fusion 360: File → Export → STEP (.step). STEP keeps exact edges and hole circles and enables hidden-line detection — always prefer it over STL.
- Upload. Drop the file on the Xyrek sheet. Faces are labelled SKETCH n rather than Front/Back/… — the direction a STEP export calls "Front" is often not the modelled front, so the 3D isometric page is your orientation key.
- Tune the sheet. Remove unwanted measurements by clicking them, toggle hidden-edge diameters, type a sheet title. Your selection applies to every download.
- Download DXF for the view you want (or the whole zip).
- Re-import. In Fusion 360: Insert → Insert DXF, units mm. Geometry lands on layer VISIBLE, hidden lines on HIDDEN, and dimensions on DIMENSIONS — so you can discard the dimension layer if you prefer to re-dimension natively in Fusion.
04Tutorial — cleaning up the sheet
- Remove a measurement: click it in any preview — it fades out. Click again to restore it. Removals apply to the PDF, SVG, DXF, and zip downloads alike.
- Hidden-edge diameters: tick measure hidden edges to dimension features that are only visible as dashed hidden lines (a bore seen from the side, for example). Off by default to keep sheets quiet.
- Sheet title: the title field fills the title block on every PDF page and names the downloaded files. It defaults to the uploaded file's name.
- Choose your medium: the MEDIA selector in the header restyles the sheet — cyanotype blueprint, graphite on film, ink on vellum, or a sepia diazo print. Your choice is remembered on this device.
05Other CAD & STL notes
Xyrek reads standard STEP, so any CAD package works:
- FreeCAD: select the body → File → Export → STEP with colors (*.step).
- SolidWorks: File → Save As → STEP AP214.
- Onshape: right-click the part → Export → STEP.
STL also works (assumed mm, capped at 50k facets): circular holes and bosses are recovered by fitting circles to the facet loops, so they still get Ø and location dimensions. But edges stay faceted and feature-step dimensions are disabled — a tessellated fillet would read as a staircase of bogus steps. Export STEP whenever you can.
06What gets dimensioned
- Overall width and height per view.
- Hole / boss diameters (Ø) with leader lines, deduplicated by size — five identical holes get one label.
- Hole / boss locations from the view's lower-left datum: X distances stacked above the view, Y distances on the right, deduplicated by value (holes sharing a centreline share a dimension).
- Feature steps: long visible edges at intermediate levels — a base plate top under a boss, a shoulder — get their own measurement inside the overall extents.
- Hidden-edge diameters when the hidden-edge toggle is on.
Labels are placed with collision avoidance: each label tries a sequence of positions (slide, flip sides, extend its leader) until it overlaps nothing.
07Formats & limits
| Direction | Format | Notes |
|---|---|---|
| In | STEP (.step / .stp) | Best — exact edges, hole circles, hidden-line detection. Converted to mm by the reader. |
| In | STL (.stl) | Assumed mm, max 50k facets. Circles recovered from facet loops; no feature-step dims. |
| Out | Multi-page A4 — one dimensioned sketch per face, 3D isometric last, title block on every page. | |
| Out | DXF | R2010, mm, true DIMENSION entities. Layers: VISIBLE, HIDDEN, DIMENSIONS. |
| Out | SVG | Per-view vector drawing, blueprint-styled. |
Upload limit: 80 MB. Processing happens in memory; uploads are deleted right after conversion, and generated drawings expire after a few new jobs — re-upload to regenerate.
08Troubleshooting
| Message | What it means / what to do |
|---|---|
| Unsupported file type | Only .step, .stp, and .stl are read. Export STEP from your CAD. |
| Could not process geometry | The file is malformed or an exotic STEP flavour. Re-export as plain STEP (AP214/AP242); in Fusion 360 use File → Export rather than a cloud share link. |
| Job expired — re-upload | Drawings are kept in memory for the last few jobs only. Upload the file again and re-download. |
| File exceeds the MB limit | For STL, reduce mesh resolution on export. For STEP, export the single body rather than the whole assembly. |
| A dimension sits oddly | Very dense parts can exhaust the label placer's candidate positions. Click unwanted measurements away, or toggle hidden-edge dims off. |
09Pricing — free beta
Xyrek is free while in beta — every feature, including DXF export and the everything-in-one-zip bundle, with no account and no watermark.
A Pro tier is planned for later: the CAD round-trip (DXF), bundle downloads, larger uploads, and custom title blocks will become Pro features, while uploading, previews, and PDF drawings stay free. Nothing changes until then, and this manual stays free either way.
10Disclaimer
Verify before you manufacture. Xyrek generates views and dimensions automatically from the geometry you upload. The output is provided as is, without warranty of any kind — accuracy, completeness and fitness for a particular purpose included. Always check every dimension against your CAD model before using a drawing for manufacturing, quoting, or any decision with real-world consequences. Xyrek and its operator accept no liability for scrapped parts, production errors, or any direct or indirect damages arising from the use of generated drawings.
Your files. Uploads are processed in memory and deleted immediately after conversion; generated drawings are held briefly in server memory (they expire after a few newer jobs) and are not stored permanently. Usage statistics are collected in anonymised form only — no raw IP addresses, no accounts.
