    Meaning of ANSI B... part numbers (ex:B1831BH080050N)

    The part number code above is defined in ASME/ANSI B18.3.1M. You are correct that this is a M8 x 50 long socket head cap screw. The "B" in the part number specifies that it made of alloy steel, class 12.9, with zinc coating per ASTM B633, FeZn5, type II. The "H" stands for hexagon socket, and...

    Lock Nut Type

    What are the advantages or disadvantages of a deformed thread locknut as compared to a nylon insert locknut, other than higher service temperature? Thanks in advance.

    Multi-Assembly BOM

    Does anyone know if a traditional DOD-style, multi-assembly BOM can be created in Pro? What I am trying to do specifically is create a two-dimensional repeat region for multiple assemblies. The rows in this table should list all parts found in all assemblies, and the columns should list the...

    Aluminum Weldment Stress Relief

    What is the proper temperature for stress relief of a 6061 aluminum weldment? I have an internal company reference that lists 625-675 degrees F for 4 hours, but one of our suppliers told me they typically hold for 2 hours at 375 deg F. What would the difference be in final material strength...

    Oldest ship on Lake Michigan (101-year old steamer)

    Can anyone clarify for me how this ship is powered? The article says, "The steam is created by heating Bunkersea fuel, a substance Rogers said was like 'road tar,' to 230 degrees." I assume that the author is confused, and it is actually water that is heated to 230 degrees by burning the...

    Dimension without numbers

    An alternative to Justkeepgivener's method is to change the symbolic name of the driving dimension in the part model, and then display it on the drawing. To do this (in Pro/E 2001) select Modify, DimCosmetics, Symbol, pick the dimension, and enter a new name (such as LENGTH, A, L, etc). On the...

    Effect of surface finish on coefficient of friction

    Is it possible to match drill and ream two or more holes through the plates for press-fit dowel pins? This will gaurantee zero slip as long as the dowels are sized to prevent yielding. -Andy

    Engineering Library recommendations

    The book that I refer to more than any other on my shelf is The Designers Manual by Ted Bilichniansky. This 80 page, self-puplished booklet is "A no-nonsense guide to design stress calculations...one that makes learning easy by substituing practical examples for words". The instructions on...

    Setting up Formats

    Turn on "Snap to Grid" under the environment icon and adjust your draft grid so that it correlates to the line spacing on your drawing format (e.g. 1 mm, .0625", .050"). Andy

    choice components in asm section view

    Alexasa, If you select "Excl Comp" in the MOD XHATCH menu, the part appears un-cut by the cross section. This only works for a total cross section, not for an area cross section, and the menu selections described are for 2001, not Wildfire. Andy

    Deleting Pro/I Reference

    I created a Pro/E interchange assembly to swap out a large number of fasteners in my "product" assembly. This replacement was a one-time design change - I will never use the interchange assembly again. However, when I attempt to check the product assembly into Pro/Intralink, I am required to...

    One directional constraint

    I have created a model of a welded structure using shell and beam elements. This structure has two mounting plates that are bolted to a concrete floor. I have fixed the plates at the bolt holes in all directions. I would also like to constrain the the base plates across the rest of their...

    Surfacing question for all surfacing gurus

    You can hide the surface transition edges by using the following commands: In a drawing - Views, Disp Mode, View Disp, No Disp Tan; or Views, Disp Mode, Edge Disp, Erase Line. In a Model - Environment (earth icon), Tangent Edges, No Display. If you want to remove these edges regardless of the...

    Exporting images to Word

    Can anyone tell me an efficient way to export an image of a Pro/E object into a format that can be inserted as a picture into an MS Word document? I am interested in transfering both shaded color images and black and white drawing type images, and need to strike a balance between file size and...
