Hi

I´m doing my first site plan in Revit, and I´m not sure what is the recommended way to show site drainage. The project is small (a house), and in Autocad I would normally just draw different types of dashed lines to represent surface water and foul drainage pipe runs, and various symbols to represent manholes etc. At this scale levels are usually worked out on site by the contractor, so calculating falls is not really necessary, although it would be useful to know how to do it if the need arose...

I was going to just use detail lines in a drafting view to keep things simple, but I´ll want the drainage to show up in a number of drawings so this might not be the best approach. What way do users normally do this?

Thanks

S

Generally I show all drainage on my site plan model, I usually require a survey of the site, sometimes I go out and make my own if it is really simple. After you get the hang of it, it is not so bad and it shows in all views which is worth it. Pads are kind of difficult, that is pads next to pads sometimes you will have interface problems and little 1/32" thick dirt walls. I worked out a way to to show curb gutter and sidewalks that is very accurate.

@mbsteve,

thanks for the info, I haven´t done a linked model yet (which I assume is what you´re referreing to), so this is probably a good opportunity to try it out. In terms of actually drawing the drainage I´m still not sure whether I should model them belw the ground surface (and somehow make them visible), or use representational line on the surface of the site. What what do you do it?

Carefully read through the creating a topo surface from an imported 3D data file. Essentially you import the surveyor's 3D model, then you ask Revit to create it's own surface from the data that is in the surveyor's model. Use only the major and minor contours, as points files. When working with Revit you don't draw the contours as you might in AutoCad, you merely insert a couple of elevations and revit draws all the contours creates or modifies the surface. The site work area of revit is the most challenging portion of the program I have found to work with. Once you get the hang of it, you will be rewarded although there are still some bugs to be worked out. I am attaching a short tutorial that I made up on street work I hope it helps.

Good Luck
