Yeah, that’s too old of a version. There was some bugfixes relating to generation output.
I’m using a 2017.01.20 version.
Try this Mac X development version:

Has anyone made an engineering scale? I’m being lazy so if anyone has a file and is willing to share it, it would be greatly appreciated!!! I want to use it for school but I don’t want to buy one.
I posted this in your other post requesting a file.
They do have an engineering scale you can download and print to acrylic or other material of choice.

So nice Dan! I purchased wooden rulers and wonder about your settings. “My” rulers look like they are the same thickness. Any advice is appreciated. ~GF Newbie
