CAD Programs
CAD Programs - (Computer Assisted Drafting) come in a variety of formats. Some capable of 3D modeling and other 2D. It all depend on what the pocket book allows you to spend. You can also find some FREE software that can do the job.
The catch wit full size drawings larger than 8 1/2 X 11 are not achievable with your standard printers, so you may need to find a print shop that may be able to plot the file for you. Many of the print shop will be able to plot the file typically DWG format, however you may want to find out first what CAD programs they support, this will help with choosing the right software for you. Another option about printing is to tile the drawing so you can use you printer to print them.
My native program is AutoCAD, however this tools is far more the tool needed to make 2D drawing to construct model planes. You could probably find something on the WEB that suits your need for the right price. Below are some suggestions on popular CAD software, however not all are affordable.
Recently I have discovered a full CAD program in the $200 to $350 USD range and will provide the tools to developed 2D or 3D plans of your project. IntelliCAD was an open source CAD program at one time now being developed by several firms into various disciplines. Professionally this program is highly recommendable for the price. They are also customizable and support VBA. This allows for new tools to be developed through VBA (Visual Basic for Applications).
The free versions are fully capable. No time-outs; no critical features disabled, such as saving to file; no advertising. These are significant packages, ideal for the small shop, student, and hobbyist.
Be clear that this isn't CAD welfare by corporations for corporations. These CAD programs are free in the hopes of (1) increasing mind share; (2) upgrading from the fee version, plus ancillary costs; and collecting data on potential customers. After all, the easiest person to sell to is an existing customer (provided said customers don't hate your guts for screwing them around).
