    VBA see action as it happens

    I am writing some VBA code for some standard drawings that we produce. Is there anyway that I can see things as they happen? An example would be that when you draw a circle, you can use the mouse to locate a point and then "pull" the circle to where you want it to go. You can see this visibly...

    HSS Beam Section Modulus 2005

    I got this response from the AISC. I wish there was a way of verifying the table numbers. I guess the best you can hope for in rectifying the equations to the table is to get close. ___________________________________________________ The tables in the Manual are not meant to be reversed...

    HSS Beam Section Modulus 2005

    There is a fair amount of tubes that do not met the requirements. HSS8x8x3/16 is an example. Once the section goes past the non-compact region, I'm having difficulty determining the rational to get the same results shown in Table 3-13 of the new manual. The CD of examples that came with the...

    HSS Beam Section Modulus 2005

    Does anyone no how to get the effective section modulus for hss columns for Slender flange and web elements. I have tried calculating the I(effective) with the b(effective) removed from the compression side. TheI calculate the new section modulus based on the new area and displaced NA. I'm...

    pc3 trouble

    We just "upgraded" our plotter from a Xerox 8830 to a Xerox 510. The salesman claimed that the new printer could print even finer lines than our previous printer. He was right but...If I print using window setting for the printer, the line quality looks pretty good. A little lighter than...

    Horizontal Array Conditional Sum Product

    I am having trouble with the following formula. I am trying to add a series of numbers based on the following criteria: Row 7 must be a blank number Row 6 must contain certain "triggers" if these two conditions are met then sum the related cells in Row 9...

    Sealed calculations for connection design

    I've been on both sides of the issue having worked for different fabricators. Sometimes the EOR for the project designs the connections; sometiems the fabricator designs the connections. When you specify an AISC certified fabricator, I believe that the plant is required to have an engineer on...

    Layer Toolbar Settings

    Thanks!!!! That was really annoying.

    Layer Toolbar Settings

    I've been using the Layer Toolbar to change layers, or to find the layer of a line. Pretty simple really. All I do is "click" the line in question, and the lines layer shows up in the layer toolbar. If I want to change the layer, all I do is use the toolbar to select another layer. I've been...

    Max SDI Construction Span

    Thanks you for your replys. Doesn't shoring only apply to situations where you are pouring concrete on top of your deck? If the steel deck is going to be your roof deck, then it seems to me that any loads listed beyond SDI cons't max is just there to nicely fill out a table, and is really...

    Max SDI Construction Span

    My question is simply this. If SDI limits construction spans to a certain maximum span, is ther any practical application of a cold-formed steel deck beyond this span. For example: 20 ga B-deck 3 span condition can tolerate 53 psf for equal spans of 8'-6", but max SDI construction span limits...

    bolting torque

    I have found the turn-of-the-nut method to be impractical for most applications. I do believe that it is the most reliable, but many inspectors refuse to accept it unless they are right there watching you install each bolt. I prefer DTI's mostly because they can be check after the fact. I...

    Light Gage Curtain Wall

    In the past when I have seen Light gage curtain walls they have framed from the ground to the diaphragm as a support bypassing the structural beam. I now have a client who wants to frame from the ground to the bottom of the beam. The problem I see here is that I don't really want this to be a...

    CJP Specification

    I saw that, and was wondering if that only applied to the engineers drawings (the structural set). Does the same go for fabricator's erection prints as well? Thanks for your help.

    CJP Specification

    Does the fabricator have to call out a weld specification for a field CJP weld. The previous fabricator I worked for always just showed CJP felds on the erection drawings, but was never specific about the procedure. The place I work nows head engineer insists that ALWAYS calling out a specific...
