This plugin can work out area, volume, length weight and costs in sketchup.
Measure the area of walls, slabs, roofing, flooring, cladding, and more. The calculation is done for both projected area (for objects with thickness) and surface area.
It produces a quick Material Report providing the surface area measurement of all the materials in your SketchUp model.
Quantifier Pro?s volume calculator is applied to calculate the total volume of groups and components and any nested objects inside. It can also work out the volume of objects which are not water-resistant solids.
It can also determine the volume of concrete, gravel, topsoil, water tanks, and more.
To compute the weight of the objects in your sketchup model, attribute a unit weight density to the objects layer.
Unit weight is attributed with volume, area, or length.
