TDT - Productivity solutions for tech illustrators.

Complete this pipe by adding a horizontal mirror of the end hole shape that you saved earlier.

Next month we will apply some of these techniques to creating isometric hoses.

Your new challenge is to find the most expensive method of producing isometric piping drawings from paper engineering data. 

Provide enough information to verify your find. Snail mail your submission to Invotech, PO Box 952, Miller Place, NY 11764.
