Designer Plus DesignCAD and Designer Plus require remarkably little resources. This is because when DesignCAD was written computers were slow and expensive. Creating a program for the masses which requires the most advanced gizmo to function would have made it more expensive than the masses would buy (1949 Volkswagen beetle with turbo charging and air conditioning). DesignCAD is a DOS program and it will run on considerably less resources than I am recommending here. The recommendations below are based on your intended use, if you are going to use color shaded or textured images the the minimum line drawing recommendations will drive you crazy waiting for the computer. Line Drawings:
Shaded Drawings: **
If you are not sure the computer is even the answer to your needs, do not invest money in hardware until you know what you do need. I started using DesignCAD 3D and wrote the beginning of what has become Designer Plus on a PC-AT 286/16 Mhz computer with 4 M RAM, 40 MB HD and DOS 4.0 OS. Most of Designer Plus was written on a 386/33 with the same 4 M RAM and 360 MB HD, inside of Windows 3.1 under DOS 5.0 OS. So the machine is not the issue, that you can use it, is what is important. * The DC3 and DP will use less than 10 meg, however each job you estimate and draw will use about 6 Meg.
**Texture mapping will require even more advanced technology.
***Texture mapping is not even worth trying in DOS
***** Shading is the same as DOS but texture mapping needs a lot more. DC3, DC2000 and DP will use less than 100 meg, however each job you estimate and draw will use about 15 Meg.
