Technical drawing

[wim (Wim Dekeyser)]

Hi Tobias -

@user1951

Are there extensions for Rhino 7 with symbols, for creating efficent correct technical drawings?

No.
That feature request is on the wish list as RH-36472 Geometric Dimension, Tolerance and Process symbols needed

Apart from that, there is a font that you could use but I wouldn’t say that it qualifies the “… for creating efficient correct …” requirement that you have. See:

GD&T (ASME Y14.5M) for Rhino WIP positive Input

I have been using RHINO for over a decade now as a manufacturer, Creating precision engineering models of Residential and commercial audio / Video systems integrations. I use Rhino to create all of the parts files for manufacture with its inherent ability to export virtually into any other CAD/CAM software without problems. I also use it to create massive amounts of 2D layouts (Export to Digital PDF) for Client reviews, Vendor parts sourcing / quoting, and factory reference proofs for product as…

You could create your own library of attributed blocks so that you’d at least get asked for values and letters when inserting the block but you’d have to create all possible blocks first and also attach leaders after you’d place them… Long story short - as long as you need GD&T and you also have access to a mechanical CAD package, it makes most sense to use that other software to create your drawings.
