Default Question - PCB Design with Multisim/Ultiboard

Hi!

My friends use Multisim/Ultiboard for circuit/PCB design (custom micro-controller boards design and manufacturing), and I would like to ask them to help me to produce PCBs for my new tube gear. I'm need only PCBs, no SPICE simulation required.

However, they told me that vacuum tube library in Multisim is very small, and there are no tube sockets in library. I dig the net and found no models for Multisim, just some SPICE models (for ORCAD or whatever ???).

I downloaded 2 archives
tubemodel_3.01_win.zip - a bunch of *.inc files, e.g. 12AT7.inc
pctube_1.04_win.zip - several hundreds of *.mod, *.inc, *.csv files

All files contain formatted plain text data which clearly corresponds to vacuum tube characteristics.

Anyone knows what the heck is all this, and can it be used with Multisim/Ulitboard? I cannot ask my fiends to carry my burden, I can just lend their hardware for a weekend.

Any help is greatly appreciated !

PS. Content of SPICE files posted below.
