If you like free software and would like to see further enhancements to TdhCad, please consider the following:

• There is no marketing budget for TdhCad, spreading the word about the program requires other free resources.

• People who make money or plan to make money selling similar software have a vested interest in restricting the information about free software.

• You can help by:

• Rrequesting that editors of publications about CAD software include articles about free software.

• Write your own reviews and articles about free software for inclusion in media such a Wikepedia.

• Spread the word among your colleagues about the availability of free software and ask that they consider these suggestions.

Free and low cost software is the best, perhaps the only method of constraining the prices charge by established software vendors. It is up to the user community to ensure that free and low cost software remains viable.
