[Exporting 2D drawings (from a 3D model) into usable 2D autocad files]

Illustrator has the ability to open Autocad's dwg format directly without the use of Autocad as an intermediary.

My suspicion would lie in either Illustrator not supporting a certain type of curve or spline or the accuracy of the file is too low.

Or the exported dwg file had insufficient accuracy for the units involved.

The first can usually be addressed by exporting to version 12 of autocad's dwg.

The second by using six decimal places of accuracy when the units are inches or one decimal place if they are millimetres.

Thank you so much for this,  I adjusted the acccuracy to 6 decimal places before exporting to .dwg and that seems to have solved the problem.  The CNC company can see the curves much more accurately now.

Hello,

 

I have a 3D model on vectorworks and I've created 2D drawing sheets. I now need to prepare 2D drawings to send for laser cutting - these need to be in autocad. How can I export the 2D drawings into usable 2D dwg files that I can edit?

 

Thank you!

Hello.  Did you have any luck with this? and have you had the items laser cut?

 

I've had a problem when i've exported my 2D drawing into a DWG for a CNC cut. The shape is a series of sweeping curves The CNC company use autoCad to open the DWG file and export it as an Adbobe Illustrator file.  The resulting CNC has altered the curves, flattening it in areas so it loks quite different.

Speaking to the CNC comapny they suggested exporting straight to Adobe illustrator, to bypass the autoCAD stage. but I can't find an option to do this.

 

They said they've had a few problems over the last few months with files originating in VW
