I went on the NZ HP Compaq website & found this machine:
HP Compaq dc 7800
Choose Intel Core Duo Processor E6850 or better depending on your budget. Choose 1066 front side ebus 4 GB of the fastest ram - important since the graphics card on this machine shares the system memory - this is how...
I lay out all of my production drawings in paper space and line up the layouts in order I want them to print,naming the model tabs by the Mark # of each part. Then I plot,"all model tabs" and the drawings come out in some absurd and useless order - 30 to 40 sheets of scrambled pages. In...
I just did replace my old HP Workstation with a new Dell, with an Nvidia 512MB video card, so I am OK there. I think that when I replaced the four going on five year old computer, I realized that the CRT was going on ten.
Thanks for the recommendations.
Has anyone had experience with the Dell Ultrasharp 2208 WFP Monitor? I need to replace my ailing CRT. Not asking for promotion or sales - just useful review of its pros and cons for AutoCad.
A five axis laser will do all of the beveling you describe very quickly and efficiently. Parts can be drawn in AutoCad and converted to DXF files which the machine will read. The five axis laser costs about 1/2 million dollars, but shops that own this equipment will subcontract the work at...
Thanks for the info (and the humor). The 2000 psi concrete comes from the literature of both Simpson Strong Tie and USP Connectors. I belive they are stating how well their post anchors work in minimal conditons (i.e. 4" of embedment in 2000 psi concrete). Never mind all of that, I decided to...
I am looking for the pull out rating on a 1/2" anchor bolt in a concrete slab. The anchor bolts are conventional J-bolts with 4" or greater embedment in 2000 psi concrete.
Use a 1.5" or 2" diameter hole saw to cut out the dry wall. The pilot drill for the hole saw will work as the pilot for 3/8" lag screws. Then use stacked 1.5" or 2" diameter fender washers for the bearing. Make a template from 3/4" ply for the size of the ledger. Use it locate the holes in...
Stay away from the MC's, they are terrible to roll, the web becomes concave and the flanges go out of parallel. Plate stringers work well - develop the helix in 3-D to get the flat layout, them water jet or laser cut from plate. The beauty of plate is that you can include in the flat layout...
I don't know if this will be helpful or not. In NYC we fabricated a metal and glass tower in a large hotel atrium (fully enclosed). We were advised by our structural engineer to use 15 psf. We have also been advised to use that figure on elevator lobby metal and glass partitions, but I have...
I vote for 100 psf. Museums often change hands and function - one day photos the next sculptures, etc. Forklifts are common and not all operators are pros. I was working in the Guggenheim, NY, when a 36 W 350 was dropped on the spiral ramp during installation of a sculpture.
Elliptical forms are very interesting to build. If you use any sort or steel profile (rectangular tube) for the stringer, keep in mind that rolling equipment for curving the stringer works only on a fixed radius curve. The work-around is to draw the ellipse in AutoCad, take one typical quarter...
If this is an exterior stair, stitch welding can become an issue, allowing water to get inside the section. I have seen cases where the resultant rusting (rust is about six times the thickness of the parent steel) has actually jacked apart and broken the weld (this was in corten steel, none the...
