![]() total concrete needed for my project in the end was - 0.4 m³ orĤ00 cm³ respectively due to there being 5 posts 0.08 m³ x 5. I know this is a very elaborate and elongated answer but hopefully it may help someone who is struggling with calculating volumes for materials. geometry selected Entity Info indicated 18 Entities. Keep in mind that SketchUp is a surface modeler so there won’t be anything inside the skin of the box. If there are no stray edges, holes in surfaces, or internal faces it should show the component or group as solid. Personally I was intriguied by sketchup’s answer for the volume and found it questionable? to sate my curiosity I deconstructed the form into 9 equal cubes/rectangles as I know the mortice is 100mmx100mm and the distance from the outside of the mortice to the edge of the block is 100mm each side(giving a total distance of 300mm for each side of the full block) this left me 8 cubes of equal size in the end because I obviously don’t count the mortice as this represents my 100mmx100mm post and I don’t need the volume for this(basic physics - no 2 entities of matter or no 2 masses can occupy the same space at any given time - duh!) in the end I calculated the volume of one of these cubes (0.01 m³) and multiplied it by 8 which gave me an end total of 0.08m³ I then multiplied this again by the number of holes I required for my posts. Select all of that geometry and make it a group or component. Here’s how: Use the Rectangle Tool to draw a rectangle on the ground. I know that for a 2400mmx100mmx100mm post I will need approximately 2 foot in the ground for maximum support and stability with a distance of 100mm all around on every side of each square post, therefore giving a depth of 600mmx300mmx300mm. Just make a simple Solid and see for yourself. First, make sure the geometry you want to manipulate is a solid. I did this to calculate the volume of concrete I would need per post as a client of mine requires 5 2400mmx100mmx100mm posts erected for a lean to car port. With SketchUps Solid Tools you can create new shapes by combining or cutting one solid. By the way, it wouldn’t hurt to get into the habit of purging unused stuff from your models. With internal faces you have an edge shared by three or more faces. ![]() In order for a group or component to be considered solid, every edge must be shared by exactly two faces. How%20to%20detect%20volume%20information 3840×2160 679 KB even in this example which has a square mortice the volume is calculated, though I did find it questionable. Get rid of the internal faces and it should be good.
