You may want to look at POV-Ray for the 3D view.
I installed official and common. As it seems it is a program for console (like image magick). is any GUI for this available. on the mandrake server is also -mpich and -pvm. i mean if have a drawing in 2D, and i want to convert it into 3D like isometric, is it possible with this?
There is a GUI for POV-Ray, called Moray IIRC. I don't know if it is capable of easily taking a 2D drawing and creating an isometric out of it. I've not found it useful for basic drafting. Ishmal has done some experimentation with using Inkscape/SVG as input to POV Ray to create 3D renders of drawings; perhaps he can explain more about this.
Another open source program for 3D rendering is Blender. Again, it's not designed for drafting so much as for 3D rendering. It does have a GUI but the GUI takes time to learn (this may have changed lately).
To my knowledge there are no good open source 3D CAD tools, although it's been a couple years since I did a thorough search.
You can do this. Import the scanned image as a bitmap via File->Import. In Inkscape 0.40 there is also a command to convert bitmaps into vector
Do you know, when o.40 is available for mandrake rpm?
We don't specify exact release dates however it's looking like perhaps a couple weeks for the release. We generally always produce RPM's as part of the release process so a mandrake package should be available around then.
The latest i have found on rpmseek is 0.39. When i installed this rpm it was installed over an older version of inkscape (witch i got from 'urpmi') I have never known this feature from other programs. Witch version is in SuSE 9.2?
SuSE 9.2 has 0.39.
graphics, although it may not work very well for CAD drawings unless the scan is extremely good, but it could be easier than redrawing from scratch.
In xfig and qcad it is not possible to import a png or other file, i guess. I asked for an open source CAD program, in witch this is possible. Maybe Varicad?
I doubt many CAD programs would allow importing drawings in raster formats like png. You'll probably find the best supported format is the autocad file format. My experience has been that porting a drawing between different CAD programs doesn't work very well, though again like I said it's been a few years since I last looked so things may have improved.
I've tried doing 2D drafting with Inkscape but the lack of automatic dimensioning and the limited technical snapping capabilities makes it not very efficient, however I expect it'll become better for this in the future.
