Thanks Adrian and PHP!
There I was about 45 minutes ago, and I thought to myself, I'll just check quickly to see if there are any video tutorials on YouTube to show how to do a fill in QCad, and some very helpful chap by the name of Adrian Cherry (no idea who he is...) has posted a few videos..
So I thought I would import the D16 dxf/dwg file into QCad and see what occurs. I can't use the words I want to use on this forum, but WOW, what a program, and so much more powerful than TurboCad from what I can see so far.
What I really like is the auto-polyline tool which is extremely clever. Also how the program shows the shortcomings in the TurboCad draughting by telling you the co-ordinates of the gaps in the lines when you try to do a fill.
30 minutes ago I bought a full version for 33 Euro's! I reckon I'll have all the fills done by tomorrow evening so long as I get a good run at it!
Thanks again, the D16 may just see the light of day after all.
JB.
