I sent TurboCAD two of my drawings and they recommended TurboCAD LTE V6. Not knowing what I was doing, I picked up a boxed version which turned out to be V3 for $40 and loaded it into Windows XP 32 bit. One of my friends told me that he judges cad programs by how long it takes him to draw a line without reading the instructions. Well the clock is ticking. I opened an existing AutoCad drawing and tried to draw a line from the mid point “mid” of a line to the end “end” of another. No can do. The inputs are “invalid” Any ideas how this is done?
