Keep in mind that as your HDPE pipe expands slightly in diameter during testing, it will also contract (or try to contract) in length. You need to be sure to properly anchor the pipe ends, or allow for this contraction. Since your test pressure us usually larger than operating pressure, this...

Two things: First--Is the printer invalid? Try selecting another one or add the problem printer again from Windows. Second--As I read your message and noticed your handle, I realized that my MP3 player (set to random play) had just started "Cheeseburger in Paradise." All hail the...

My 2 cents... I find that this problem usually occurs when I am using osnap while drawing. Remember that osnap will snap to all three coordinates of the selected point. As a civil engineer, this usually happens to me when working with topographic files generated from flown aerials. All the...

Check the system variable "highlight" (type "highlight"--without quotes--at the command line. If it is set to 0, selected objects will not appear dashed. Set it to 1 to highlight selected objects.

I ran into the same problem recently. I know this isn't a lot of help, but the only way I found to correct it was to do what you suggested: create a new drawing and insert the other into it as a block. If you find a solution, be sure to post it here. Good luck.

Since you have already eliminated the best ways to get large files to load faster (better hardware: more RAM, faster processor), your choices are somewhat limited. Here's what I'd suggest. First, freeze layers that you don't need to see while working on the file. For example, if the file is...

Can you tell us a little more about the problem? What version of AutoCad? What hardware are you using (processor, RAM, etc.). Does this happen in Windows while you are running other apps?<br> <br> AutoCad hangs for a number of reasons, but if I had to guess from your previous post, I'd say...

You're right. I'm pretty sure that if we have a qualified contractor, we're unlikely to have problems. I've just never written a spec for this type of work before, and want to make sure I get it tight.<br> <br> Thanks again for your input.

Thanks for the reply. I've been looking around since I made this post last month, and haven't been able to find any way to do a wet tap. <br> <br> Our current thinking is to build a concrete pressure structure around the existing 96" RCP, and cast an angled flanged spool fitting into the top...

I am currently in preliminary design for a new treated effluent discharge pipeline. The new pipeline will likely be in the 42" to 48" diameter, and the downstream terminus will be a connection to an existing 96" RCP outfall pipeline force main, operated by a joint powers agency. The force main...
