Hi,
I was wondering if anyone had any recommendations for drawing software that could be used for working out horn folds. I saw there was a forum from a while back which suggested using sketchup, but it looks like they've updated the software and it's not as suitable anymore.
I have designed a horn model in hornresp, and can export the coordinates in txt or csv form, so I want a sofware that can import these, in two dimensions. Then i can work on the folds from there.
Does anyone have any suggestions?
Thanks

There are just so many variables that I don't know of any software that can acheive this. Hopefully someone will prove me wrong!
Many sims will never fit in a rectangular box. However it is possible to start with a rectangle & then using a pre-defined fold optimise the dimensions to get the horn shape that is close to what you want. At least then you know it will fit in the box.
At one point I started experimenting with horns in trapezioidal boxes to get the folds I wanted.
This is the technique I eventually used with Solidworks - The main point being that being parametric CAD, changing the driving dimensions of the assembly will update the sizes of the parts.
Plot out the folded horn shape and add a sketch which plots the horn path and width changes.
The sketch then drives a secondary sketch of the unfolded horn.
The dimensions of the speaker walls are then varied which when rebuilt, updates the unfolded sketch. (and all the component parts & drawings etc!)
Post 5 in the Xoc1 TH18 thread has an example image with the relationships.

However there are other ways of doing this - Brian Steele's excelent spreadsheets can allow you to optimise certain folding syles
