The false perspective? - more like a complete lack of it.

As it turns out you can turn that on quite easily and do proper rendering, but I confess I hit the "make it shiny" button and left it at that.

Can you post the KT88 rendered image with perspective turned on? -just curious

It should look "more real" (and more impressive) than what you've already posted.....

Perspective is nice for rendering but rather useless when doing assy mates and measuring, etc.
 
Voila! one pretty picture that's as pretty as I can make it just now. it has perspective and so on added anyway - looks a bit wide angle to me but I can't figure out if thats even an option.

I have spotted a flaw with this rendering malarkey - it takes as long to render as it does to draw them. Its an overnight job on a what I thought was a meaty PC. Hence the 300b, the KT88 or 845 takes day(s) to do high res, at which point it usually crashes anyway. :bawling:

Running SolidWorks on a 64 bit machine would be the way to go. That would give you meat, veg, potatoes, and cake.:D

I'm stuck at 32 bit with 4 gigs of ram for the time being.

What are you running for a PC?

My PC right now is:
AMD phenom 9500 processor, 4 gig ram and Vista 32 not exactly a three course meal, but hardly a salad either :)

I have access to an intel I7 based rig at work with 16gb ram and was intending to try that, but frankly was in too much of a hurry to get outtathere on Friday.

On a slightly more useful (?) note I've manged to get my hands on a few more valves that are no use (to me), so more to follow.

:devilr: mwhaa haa haa :smash:

I'll go out on a limb by saying an i7 9500 would be significantly faster.;)

6L6G perhaps?

What's new, Andrew?

Couldn't you estimate the internal dimensions, so that you wouldn't need broken tubes to model? Then later if you found a broken one, you could go back and fill in missing dimensions. That way you might set up relations and equations (and design tables!) and learn that part of SW as well, although you probably know these by now?

I dabble with SW2006 on my old 800MHz 512MB laptop, so no rendering for me...
 
Back again...

Whats the phrase regarding bringing a post back from the dead?

Seems I found some time to do the mucking about with the models again after a fairly busy period (read mental at work) - I'm now allowed to do "geek stuff" again as the other half puts it.

So cuuently there are SW 2009 models for:
Mullard el84
RCA 845
Cetronic 300b
russian OTK "6sn7"
Mullard ez81
12ax7
GEC kT88
RCA 6AS7G
Nixie GNP7
and an approximation of a 6j5G - GT shape but with 6sn7 insides because i cant bear to smash up an otherwise useless (see orphan) "coke bottle" tube

Still to come is a representative 7 pin tube - probably a ec91 because i have a few

also available are the sockets for this lot

unless someone has a better idea PM me for links to these if required

On another front wouldnt it be great if i could find time to build the bally amps that are rendered - got all the metal work but these things are moving with a speed only rivalled by the three towed (?) sloth and glaciers

Cheers

Hi Andrew,

I have a Mullard xf1 EL34 (Dynaco branded) whose bottle was cleanly broken off by the rad flusher who sold me the amp. He thought they unscrewed. :eek::bawling:

It would make a nice supermodel for your SW efforts though. It's yours if you want it. the bottle is intact; it slides back into place.
