    Type 2 Weld (UW-12) for Shell Longitudinal Seams

    We are designing a split shell gallery sections on a tall tray column and plans to use a single butt weld with backing strip on the longitudinal seam and a groove weld on the flat plate ring closure on both ends of the gallery section shell. Is this type of weld on a Category A joint...

    Joint Efficiency

    Thanks guys. Appreciate the help. I'll use 0.85 efficiency per UW-12(d).

    Joint Efficiency

    I'm designing an aluminum pressure vessel. Shell and head material is SB209-5083-O. Shell weld is Type 1 and torispherical head is seamless. There are no radiogragraphy for this vessel. What efficiency will I use for the required minimum thickness calculation for the head? I'm using a 0.70...

    ellipsoid

    Set variable pellipse = 1 and draw a full ellipse as a polyline. Draw a line along the major axis of the ellipse. Trim the ellipse and line, then use pedit to make your polyline profile. Revolve the profile 360 degrees and you'll have your ellipsoid.

    math packages for ee calculations in autocad EE software

    You can use AutoCAD's built-in customization programs to create the calculation routines you need. Have used this method to do pressure vessels calculations (sheel/head thicknesses) and then automatically draws the top, elevation and section view of the pressure vessel.

    Pressure Vessels

    Lee H, Have seen a demo routine at Cadalog.com that draws a typical pressure vessel in 3D (filename 3DPV.vlx). http://www.freecadapps.com/shareware.php Look for the file under AutoCAD General->3D tools.

    xline command

    Try this using a space to repeat the last command. Works at the command line, but you can give it a tryon a macro. ^C^C_xline H pause; V @0,0;

    OK, Here is the "Burning" question..

    Smokehouse, Can the drawing of the mold/dies be done parametrically in 2D? If so, have you tried writing a lisp program to do the task. I've created a demo program that draws pressure vessels/pipe flanges in 3D. I don't know if the concept can be applied to your situation...

    Analysis of semicircular annular plates

    Have you tried transforming the analysis used in Table 24 Case 31 to suit your loading/support? (Roark's 6TH Edition p.439)

    Ver. 10 lsp routines in 2000 possible??

    Depends on the complexity of the lisp functions used. For basic functions, I've tried a release 2.6 and it works in A2000+. Why don't you give it a try or if you can send me a copy, I'll take a look at the routine and make it work in A2K (if it's not compiled). Enmail...

    Convert LISP to VBA

    DanielHyde, Could you send me a copy of the routine. I may be able to have a better understanding of what the problem is all about. Email: dparc7491@yahoo.com

    Convert LISP to VBA

    Are you referring to Visual Lisp functions? These functions are patterned after VBA but the format is similar to Autolisp. You can also use plain AutoLisp (see the function "getfiled") which gives the user the flexibility to look for the directory where the xref drawings are located.

    VBA or VB

    AlexDring, I'm currently looking for sample drawings of structural details used in the industry. I'm working on a lisp program to do structural detailing using plain Autolisp. Would it be possible to share the structural details that you do in exchange for a complimentary copy of...

    Text Lisp

    Yes you can do that with a lisp program, but may not be worth it (time spent in writing routine) for single use only. It's good to do it via lisp when you are adding additonal text to multiple instances in mutltiple drawings.
