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...
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...
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...
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...
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...
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...
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...
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...
In ACI 318-02 D.5.2.3, hef is limited to cmax/1.5. Figure RD5.2.3 is not particularly helpful since c1=c2=c3=4". My question is that for use in (D-6), is the cmax correct? If I have two anchors in tension that are 16" apart, and c1=c2=13", and c3=cmax=29", is hef limited to 19.33"? The figure...
We were just upgraded to 2004. I have a four button mouse, and the thumb button use to be customized to give a pop up menu of osnap settings while drawing. I know that Shift right click will do the same thing, but I'm a creature of habit. Is there a setting in autocad that will turn this...
Does anyone know if California is accepting the IBC values for shear wall design. I would like to use a light gage steel diaphragm over steel studs. I know that the 2001 CBC has values for plywood, I was just wondering if they accepted more current design values.
Here is a situation that I have run across in the past, and was wondering how others would adress it.
Say I have a square tube and a channel crossing each other at 90 degrees with the back of the channel to the tube. I have to angles welded to the tube and the angles are boted to the web of the...
I'm getting ready to take the PE soon. I've never had an occasion to look at AASHTO's bridge design book, but I've just recently borrowed one. I was going throught some live load distribution examples that the NCEES puts out in there sample exam. The problem illustrates a 2-Lane, 85 ft span...

I am fairly decent in Excel and Lotus. I have used Excel for years and have gotten fairly decent at it. The only problem that I have with Excel is the way it prints. At work my boss prefers to use Lotus. the only advantage that Lotus has that excel does not that I have not been reasonably...
I am trying to draw a line that is broken at the end and the beginning. I would like the line to be continuous in between. I am trying to represent beams in a floor plan the frame between other members. I know that I could just shorten the lines, but it would be nice if I could use set the...
I know that the IBC Code no longer allows a 1/3 stress increase factor for working stress design. However, the code states that if two or more transient loads are used it is permitted to multiply the combined effects of the transient loads by 0.75. I used to only apply the old 1/3 factor to...
The majority of the roof systems that I have designed are flat roof systems, and for th most part are pretty easy to design once the loads are established. One thing that has always bothered me is sloped truss design. I know that joist designs are assumed to be pinned/roller support condtions...
