Hi all, Thanks you for your replies. I actually found the same problems David and Andrew mentioned. In bigger models there is a lot of line overlaid, and you don't have control over the block size. I didn't know about mdl2m, that is a big time saver! Because most of the time I was manually extracting the position of each block in my parametrized system.
I'm also interested in the the 'black box' that Jack mentioned. Is there a tutorial or memo on the topic? I found this https://github.com/casper-astro/publications/blob/master/Memos/files/Black_box_memo.pdf but it seems to focus on creating black boxes from existing blocks.
