I've seen cutlist and had a look at ComponentReporter and they don't do quite what I want. They seem to produce component 'cutting diagrams' but don't seem to have the dimensions of the mortices, tenons, cut outs etc.
I guess it just a matter of manually dimensioning all my components and sending them to Layout. Just seems a bit of a chore, there are 30 components in this model and I've got other projects on the cards that will have considerably more.
I'm no computer whiz, but maybe this could be a potential plugin to develop if there's not one already...
