I have a project where i have to delivere a volume of a water reservoir. As ypu can see in the screenshot i have a scan from the construction and created the bottom of the the scan in trimble realworks wich i exported to sketchup as a surface (included in the file here). The surface at the bottom is not flat. I have created the top of the resovoir as a flat line (the highest water will be). I would be able to se the volume of the reservoir AND use it in layout for making plans. Have been trying and testing for 2 days now but cant figure out a good workflow, it MUST be possible to do in sketchup! This software is fantastic but it usually means just thinking outside the box and i seem to be in the box all the time… Hope You can help me guys, greetings from sweden :).

Here is one method (there are many) using jointpushpull by vector then intersecting the top “water surface” and erasing the unwanted geometry. A little clean up with solid inspector and volume is available. If you need to remove the volume of the internal columns too you could use intersect or solid tools.
SketchUp can only calculate volume for a “solid”. That is, a group or component that bounds a closed region of space with no “leaks” (holes between the inside and outside) and no spurious edges or faces (ones that are not necessary to bound the solid). This requirement is often expressed as “each edge is used by exactly two faces”.
You need to close the top of your pool with a face at the water level and then fix any flaws due to the starting structure. Thomthom’s solid tools 2 is an excellent extension for finding and in certain cases fixing flaws.
