I took it upon myself to download the viewer program and install. It does open the .dwg files I linked but I don't know how useful they are without a legend or dimensions?? I suppose with one exact dimension, you could calculate the others as the template is supposed to be to scale. I will attach screenshots of each template (and I hope this works!).
From what I gather, it looks like some engineer/draftsman basically reversed engineered a presumably correct table to create these 3D models. In other words, I don't believe this is "authorized" or even necessarily perfectly accurate information from the WPBSA or IBSF. It is some interested individuals own interpretation of the pocket sizes by measuring them as accurately as he is able, and then storing that measurement information in these CAD files. This looks like it should be usable information (perhaps the individual has his own snooker table which was fitted by a professional fitter using authorized templates), but to be useful to the OP wc_mechanic Lou, this information needs to be converted into graphic information (paper drawings) for a machinist to then use to fabricate physical templates to then be used to properly fit his tables. To be clear, the term "template" refers to the PHYSICAL thing, the actual wood, plastic, or metal block that the table mechanic will use to shape the pockets. These computer files are "3D models" which are only in cyberspace, not real. These files are useful, but only to someone with the wherewithal to use them to fabricate the physical templates.
Also, these 3D models are not actually models of the templates......they are models of the actual snooker table pockets. It is kind of a "round peg in a round hole" situation....here you have the correct pocket information so from that you create physical templates and with those you can the RE-create the correct pocket dimensions on your table. It is like when they find Bigfoot's footprints. They make a plaster cast (template) which can then be used to create a copy of the footprint whenever and wherever they want.
I have not used AutoDesk programs in a decade so it's a bit hazy, but the tools look about the same as always. You can see a "Measure" tool on your screenshot so you should be able to click that, then click various "snap points" in the drawing to get measurements (kind of think in your head as you click, "(click) Measure, (click) from here, (click) to here." then it should display the dimension for the points you clicked. Might be in standard (inches) or millimeters, or possibly some other unit (like centimeters).....all depends on how the file was originally written. Then (you may or may not realize), this appears to be a three dimensional model......you can look at it from different points of view: from the front, from the top, from the side, even rotate it to any angle you want (this is the same principle by which "Hawkeye" works by the way).......then take various measurements using those different views. For instance, with a side view, you should be able to click to measure the exact height of the top of the rubber cushion to the slate bed. To see different views, you should try clicking on the various icons in the tool bar section labeled "View". It looks like these models even contain the steel block information, though I am not certain of that at this time (I think the steel block is the brighter gray lines I see in the corner pocket model.)
Underclocked, you should just play around with this viewer program a bit and you may be surprised by some of the things you can do. Have some fun and expand your horizons. wc_mechanic Lou, you have some good information here, but you still have a long way to go to accomplish what you originally set out to do. Feel free to PM me if you are confused by what I said here or if you think I can help in any way.
