I need to analyse a channel cross section using the manning equation to determine the 100 year flood elevation. Is there a free program that I can use to input the channel geometry and then apply different Q values to get the water surface elevation. I am only going to be doing one section so...

This problem can't be that difficult. There must be simplifying conservative assumptions that can be used to solve this problem. If the conservative assumptions prove to be a problem then a more detailed analysis is required. Any positive comments are appreciated.

I am trying to insert a portion of a Pdf file onto my drawing. All that I want to see is a portion of the Pdf. I selected a portion of the Pdf and put it into model space. I then created a viewport. When I try to plot nothing shows up. I believe that the problem is that I am using a black...

Thank you - That worked. Tried to purge drawing and remove layer filters but the size is still over 2.5MB. Printing this way worked.

I am using CAD 2005. I am using a plot file where each color has a specific lineweight and screening. Is it possible to print the colors so I can see how dark the colors print and the lineweight. Once I have a reference I plan on using it to select the color for various objects in my drawing...

Figured out the problem. With the new cartridge in the printer I restarted the printer and it works ok now. As part of the start up the printer must look for all of the cartridges and if only black is there it uses black for all of the colors.

Yes - product 51645A option 140. I though that if only a black was in the printer that everything would print black?

I have a HP Designjet 750C. I only print in black and only have one carteridge. I replaced the cartridge and now only items that are black on my drawing are printing. I put the old cartridge back in and am having the same problem. Can someone help please.

That was the problem. Thank you very much.
