Users can create comprehensive and synchronized project views that combine information from BIM tools – such as Revit -with images, geometry and data from other tools.

How do you subtract a surface in Autocad?

With SUBTRACT, you can create a 3D solid by subtracting one set of existing 3D solids from another, overlapping set. You can create a 2D region object by subtracting one set of existing region objects from another, overlapping set. Using SUBTRACT with 3D surfaces is not recommended. Use the SURFTRIM command instead.

How do you estimate cut and fill volumes for earthworks projects?

The volume between each pair of sections is estimated by multiplying the average cut or fill area of the two sections by the distance between them. Once these volumes have been calculated for each pair of sections the total cut and fill volumes are obtained by adding them all together.
