Many drawing services outsource production overseas — and almost none say where your files are stored, who opens them, or when they are deleted. Our answer is checkable: machines process your images under contractual no-training terms, no one views them in normal operation, and they are destroyed on a schedule you control.

Patent and design-rights drawings demand a specific aesthetic: solid black continuous lines on white, no shading, no fills, orthographic views from precise angles, and lettering that meets each office's standards. Drafting these by hand takes hours per view, and the result still depends on the draftsman's accuracy with line work and consistent stroke.
PhotoCAD interprets your product photograph and generates the precise orthographic line work patent and design-rights applications require. No studio setup needed — photograph your prototype in working conditions and turn on PhotoCAD's Remove Background mode to isolate your subject from any setting. Output meets the format expectations for USPTO, EPO, UKIPO, and WIPO submissions: solid black vector geometry, no shading, no fills, uniform stroke — with line weight set in PhotoCAD before you download.
PhotoCAD handles the drafting and the finishing. In the editor, add reference numerals with leader lines and figure labels, set the line weight your office prefers, delete or split lines, and put the figure on a sheet with a border. Filing-ready sheet templates — USPTO, EPO and WIPO formats, margins and line weights — come with the Patent pack and plan. Download the DXF, SVG or PDF and file — or open the file in Illustrator, AutoCAD or CorelDRAW if your firm's template lives there.
