... thanks Martin. That will help a lot. posted: 18 Jan 2016 00:49 from: Martin Wynne Hi Andy, I thought you might like an update on this. I have got the bare bones working, but there is still a lot to do before we have a usable new function with the multitude of different prototype chair sizes. It needs a new data structure just to contain them all. Plus new "shove chairs" functions to make them adjustable on each timber. This below is with equalized timbers. 2_171925_020000000.png Which means it will be possible only to include a basic experimental output in the next program update, otherwise it will be delayed for months. I know for DXF substitution you need only the block markers, but the chair outlines are needed so that you can see what you are doing. And everyone else can see them. regards, Martin. posted: 18 Jan 2016 02:54 from: Andrew Barrowman Hi Martin, Thank you for the update. Please don't hold up the next release for this If you can ...
