Converting an image to CAD file





weableandbob
I was wondering if there is any easy way to convert a simple graphic/picture (2 colors, sharp edges) into a CAD file. I know that Autodesk Inventor (and I would assume Solidworks and such) allow you to manually trace over an image to create a sketch that can then be turned into a 3D object, but I was wondering if there is a program that does this automatically, since tracing it takes a while.

There are several programs to convert raster graphics into vector graphics (Illustrator should go too, but that's just my guess). If what is to come of it really accurate, but almost always much rework is in order. As a rule, it is (especially for graphics without clear straight lines) so much easier and faster to use the image pixels to as "base" and then draw over it - in the case of splines. If you make the most directly in AutoCAD, go to illustrator as well, but then the necessary export / import DXF deteriorate as the result may be.

Thanks a lot. This looks like it'll do the trick.

Load up image into AutoCAD or Civil 3D, us Raster Design can convert the image's lines, arc or texts to AutoCad objects.

There is a lot of software for creating 3D-scenery from pictures. But it is either free and imperfect, or expensive. Game programmers use it. Blender, Make3d..

Some links stored in my favs (dunno how long though Razz )

As a hobby, I do a lot of VS programming. Recently I took up a project to map my own living room in a SharpDX/DirectX texture.. I use a 360 degrees panorama photographs for that, the stitching can be done quite easily with these,

.. but of course you'll need some programming skills to polish it to your needs..
