Dished Heads?

[DANIEL]

Does anyone have a lisp routine that will draw a dished head?

[Lee Mac]

Something like the CAP in this program?

yep, in fact, I'm now looking at your fittings lisp I have use for that as well.

 

I really dont need anything fancy just something that does stantrd dished heads

 

I cant seem to even find cut sheets on them, I am always having to go to a fabricator to get some kind of info on them to draw them up and well, I want to be able to draw them up and then give them to the fabricator lol.

That was one of my first programs that I wrote - very very messy programming...

Lee, here is a pdf for 2:1 heads with more precise calcs.

thanks buzzard, I was about to go looking for that.

thanks buzzard, I was about to go looking for that.

 

No problem,

 

I used to work at a shop that built ASME pressure vessels. We used to use software to perform the design and welding calculations. This software would then create a file that is used with a hardware key and lisp that would create upto 90% of the drawing based on the calcs. I just cannot remember the name of it. The program would also have all types of fittings and heads as well as welding details.

 

If I should find the name of this software I will give it a mention.

thanks buzzard, unfortunately the price on that is not going to fly with the powers to be.

The powers to be really know how to hurt you.

Here is another pdf with specs. The previous one I posted did not look correct on the 12" head. Also this pdf has smaller sizes.

[DANIEL]

thanks again, and yes, the powers to be do know how to kick me where it hurts lol, looks like I'm stuck drawing them.

[ReMark]

Maybe this program, 3DPV.vlx, will help.

Daniel,

 

I checked that one out and it runs an automatic demo for pressure vessels. It is not a useable program.

[DANIEL]

thanks for taking a look buzzard, saved me from doing it from home lol, i hate doing work at home lol

Daniel,

 

I have some good news for you. I downloaded a trial version of Codeware drafting option. I found out that practically everything in it is available for use and there is no trial time limit on it. The programs in it are *.fas or Fast Load so they are compiled, But the program gives you more than you can imagine.

 

Heads in 2:1, F&D and Hemispherical

Welded Fittings all sizes

Forged Threaded Fittings all sizes

Mallable Iron Fittings all sizes

Flanges all sizes

Structural Steel all sizes

Misc Parts

Item Ballooning

Welding Leader Symbols

 

This is all available in English or SI units.

See menu images below.

You just need to register at this site:

At this site location you get the Drafter Manual for this software in PDF format:

http://www.codeware.com/support/manuals/drafter.pdf

 

 

Here is what the site looks like, notice I have clicked the drafting option. Give it a shot, This is a great deal for free.

Also below are images of the drop down menu.

The user is limited to 60" and 120" shells and 6" / 10" fittings.

I downloaded the Drafter option only. I have full use of all options. Did you download Compress as well? That could be a reason why although I am not sure. The Drafter option is for CAD only and has fast load files. I seem to have gotton everything the program offers. I mentioned to click the Drafter option only.

 

Compress is for designing the shell and nozzles. You would use the design files to generate the vessel you designed for CAD. That would most likely have a limit as to what you can do with it. The Drafting option stand-alone is what I meant to download for the CAD routines.

Thanks for the new info. I'll give the Drafting option a look. Did not download anything yet.
