How it works

Upload your STEP file

Any CAD tool that exports STEP. Each part and each hole size gets its own reference numeral, with a key in the report.

In about a minute, see every sheet (watermarked) and its rule-check report, free, before you pay.

Pay $49 and download vector PDF, one SVG per sheet, and the check report. Links stay live for 7 days.

Sample sheets

Made by the same software you would use, unedited. The first two are real CAD files from KiCad's public 3D library (34 and 10 solids, no part names in the file, so every numeral was placed automatically). Open any sheet at full size.

USB-C receptacle: section view 5-5 with the hatched housing and contacts — USB-C receptacle, section 5-5. Front and side views, PDF

USB-A connector: isometric and front views with reference numerals 10 to 32 — USB-A connector, 10 solids. Section, PDF

Hinge: isometric and front views, numerals 20 to 26 — Hinge, 4 parts, 3 sheets. Section view, PDF

Connector models: KiCad 3D library, CC-BY-SA 4.0. These drawings of them are shared under the same licence.

What you get

Views	An isometric view plus the orthographic views that show the most of your part (front or back, top or bottom, left or right); flat views share one scale
Numerals	On each distinct part and each hole size (identical parts share one), with short curved lead lines that end on the part, in every figure where it shows; a key lists what each numeral is
Section views	Through the middle of the part, cut faces hatched, neighbouring parts hatched differently, cutting line marked on a reference view (left out if the middle plane misses, for example separate loose parts)
Sheets	US letter, black lines only, inside the 1.84(g) margins, FIG. labels and n/N sheet numbers
Check report	Every sheet checked against 37 CFR 1.84, with measured values

What it takes

Accepted	STEP files (AP203, AP214, AP242) with solid bodies, up to 50 MB
Not yet	Photos, sketches, STL, DXF; design-patent surface shading; detail and exploded views
You check	That numerals match your specification and the views show what your claims need

Pricing

$49 per CAD file

Up to 10 sheets per file, with numerals, section views and the 1.84 report. Preview free; pay after you have seen it.

See it before you pay

You see every sheet and its 37 CFR 1.84 check before paying, so you only buy a set you have looked at. Every sheet in the paid set passed the same automated check, and the report shows each measured result. The check covers formalities (margins, line color, text size, numbering), not whether the drawings show what your claims need; that review stays with you or your patent practitioner.

Order

Upload one STEP file (.step or .stp, up to 50 MB). In about a minute you see a watermarked preview of every sheet and its 37 CFR 1.84 check, free. Pay $49 to download the full set: vector PDF, one SVG per sheet, and the check report. Reference numerals are placed on each part and each hole size; the key is in the report.

Uploads are deleted after 1 day unless you order; ordered files are kept 7 days for download.
