Hi, I usually make drawing by Adobe illustrator(ai file) and export to dwg files.

And then I load this dwg file on Draftsight and transfer to dxf files to print.

During this process, there are too many nodes on the objects so it took too much time to load 

on the printing machine.

Luckily, I found 'fit' command and I found the way to reduce the nodes.

But at this moment I have to click 'fit' on every single line.

Is there command or menu that I can reduce the nodes in the whole drawing at one time?

Thanks for any advice.
