Make sure you're drawing in model space. Sounds like you may have accidently switched to paper space when you tried the pline. Remember to use the right units when using relative coordinates. @24,0 is 24" to right of current point while @24',0 is 24 feet to the right.

Thanks, vbridge and JAE. JAE, that was a very good link! It was exactly the information I was looking for. Briansch

Thanks for the response, Ron. Briansch

We are installing a rooftop AC on an existing roof. We will be installing angle framework to support the unit and curb between joists which are 5' o.c. I intend to build the curb with treated wood either on top of the deck directly over the angle framework and build it up directly from the...

In an article in March 2002 Engineering Times, the author compared a couple of softwares that support collaboration and coordination. They were Bentley's ProjectWise (www.bentley.com) and Viecon (www.viecon.com).

porf, I think I see your problem. This is your value for C29: =((C23*1000000)/C25*1.732*100)/C24 and C32 is C29 multiplied by C25 times some constant. You can see, though, that the C25 value will cancel (one in numerator and one in demominator) so the value of C32 will not change if C23...

Thanks krd. Maybe making it more complicated than it is. Dittowizard, what are you building?

dittowizard, the density of 2.4 you mentioned for this fluid doesn't seem right. You did not give any units. Are you sure this is not specific gravity in which case the density would be 2.4 * 62.4 pcf (water) = 150 pcf. The pressure then at any depth is 150 * h (measured from the surface)...

What I gathered from the description was the flow was going perpendicular to a road that was 26' wide. This would make the weir length 26'. The weir crest would then be the road length, I think. Looking quickly at my open channels book, for a LONG weir(L/H>3), the flow should be based on...

Just a side note on evelrod's comment to unload the beam prior to welding. I read a response to a question in Modern Steel Construction's "Steel Interchange", Feb 2002, (an AISC monthly) about this. The statement and question were; "It is a general rule that welding on an...

Windies, if you haven't already, reference ACI 211.1, "Standard Practice for Selecting Proportions for Normal, Heavyweight, and Mass Concrete" and PCA's "Design and Control of Concrete Mixtures". You didn't indicate what the mix was to be used for (paving, structural, etc)...

Sorry I repeated reference by ishvaaag. I need to read all the posts before I reply :)

Thanks very much for the responses to date. This forum has been very insightful and helpful. I will offer some additional background on this project. The worst case wheel load (front) is 3,775 lb (Yale GLC030 forklift w/full payload of 2,500 lb). This same vehicle with no load has a wheel...

I saw a post in another list regarding software available for truck turn templates. Go to list Codes and Standards>AASHTO, look for a thread entitled "Truck turn templates" and a repsonse by "gvd" dated August 6, 1999. I would have forwarded this post directly to you but I...

We have a structural floor system consisting of 26H9 floor joists, 40' long, 2' O.C., supporting a concrete slab. The slab is 4" thick normal weight 3500 psi concrete with 1 layer of 6x6x4 gauge WWF over 1-1/2" x 22 gauge composite metal deck (2-1/2" concrete above flute). This...
