Hello Mr Atlo ..I love your work and its quite detail and well explained . I am now unto hydroproject only and using Civil 3d but right now in little more than basic. I wish you could upload similar such videos thank you
Hi. Reading your problem it sounds like you are trying to subtract a 3d solid object with volume (The Dam) from a 3d surface object which doesn't have a volume and therefore the two items aren't compatible to perform your request. You should be able to slice your solid with the surface if you have extracted and converted the tin from the civil 3d surface and combined that to form a dumb Autocad surface which can be used to slice solid objects (make sure the surface completely intersects the dam). Otherwise, if you truly want to subtract, then You need to convert your surface to a 3d solid volume by either extracting a solid from the surface if it is a civil 3d surface, or if it is a "dumb" or static surface then you can try to extrude it in a direction to give the surface faces some body. That should allow you to subtract two solids from each other. If that still does not work and you get a Booleen error from AutoCAD then you most likely have one or more imperfections in either one of the objects you want to perform the subtraction with. Imperfections could be anything from vertices not 100% being exactly on the same locations where they should be or you might have very thin gaps or overlapping faces of the items. Double check all the vertices (set in your units options the number of decimal values very high before you do the check (many desimal places)) and then if no issues were found then I'd recreate one object using as much of the adjacent objects vertices/faces to make sure they can line up exactly. If that still doesn't work, try to slice your dam or the surface into multiple sections, then try to subtract the individual parts. That way you should be able to identify where and in which part the error might come from. Hope this helps, otherwise if the options I gave you did not work, feel free to send me the dwg and I'll have a quick look. You can contact me on LinkedIn.
@@altoroos I understood. Thank you very much for the explanation, i did it. This tutorial is very good. I am a student and this is useful for me (PS you may post more videos for us ). Thank you
Great video! could you please upload some more hydropower related videos? for example designing water channel with profile view, or maybe pressure pipe system including showing on the profile.
Thanks.. Very informative video... I am try to subtract dam 3d soild and surface 3D soild as you did in video, but I am failed to subtract.. Can you please assist
Apologies for the late response. You can't subtract a surface from a solid. You must convert the surface to a solid first, then subtract that new solid from your other solid.
Hi Hatef, Unfortunately I don't have access to this file anymore. It is rather easy to create your own sample contours and sections to practice with. So I would suggest that you draw a few lines by hand, elevate them and convert it to a surface. The rest is as simple as I've shown it in the video so it should be easy to recreate. Have fun.
This can be done in AutoCAD or the subassembly composer. Your overall goal with regard to what you would like the subassembly to do, plays a huge role in how you would go about making it.

Thank you for description I appreciated your effort, but I want to ask you that how can we create the dam water reservoir and exporting to infraworks, because in infraworks i tried to create dam water reservoir but finally i couldn't
Eng_Aram - assuming you want to create the body of water as a solid to be able to export that to infraworks? If that's what you want to do - Simply create a solid extending above the surface instead of below like I do in my video and slice the "water" on an xy plane on the elevation of your Full supply level. Delete the water you don't want and then you should be left with the "water" as a "Solid" in the dam. I have no experience using infraworks but I see there are multiple videos showing you how to move data between Civil 3d and Infraworks, so I am assuming that isn't the problem. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-yxa5dgHBum0.html Does this solve your issue?
Eng_Aram - This is more likely what you are looking for: forums.autodesk.com/t5/infraworks-forum/water-areas-within-designed-dams-and-channels/td-p/3783825 It looks like the issue is your Surface in Infraworks. It seems like there should be a large enough elevation difference between the inside of your dam and the outside. Then you would simply add water like you would normally in Infraworks to the entire extent of the Full Supply Level and then it should display the "Depth" of the water relatively well.
