# CADProps

> Online CAD viewing, measurement and model properties. Capabilities vary by format.

CADProps processes uploaded files on the server in a temporary guest workspace. No account is required.
The default retention period is one hour from task creation. A separate private original of each accepted visitor upload remains until an operator removes it.
The default upload limit is 10 MiB per file.
STEP and IGES use CAD geometry for properties; mesh measurements are approximate.
Volume requires suitable geometry; weight/mass depends on user-confirmed density.
Download validated model conversions. Partial assembly properties describe loaded geometry only. DWG is not currently enabled.

Sharing creates a fixed snapshot of one completed 3D model for 7 or 30 days, with an optional password.
Recipients can view, section, inspect properties and measure without signing in, subject to format limitations.
The original CAD file is not offered for download; loaded display data can still be captured or extracted.
Shares survive clearing the source workspace. Clearing cookies loses anonymous share management access.

Links below point to Markdown copies of public pages. Each copy names its HTML page.
Localized pages and long-tail guides are listed under Optional.
