The following images is off how I created a lego block with the use of perimitves. I found it really interesting to do and learnd how to use the "Boolean" technique and the "Extrude" tool. The measurements of the box was, 10L, 5W and 3H. The three circles created on top of the box had a radius of 0.5mm and were combined together to creat the lego block, with a hollow bottom to it.
Below are some images of how I created the lego block.
This image to the right is of the main box and the three circles palced above the box to form the shape of the lego block.
To the right is a image of the block with all the shapes combined together and from the top right image, it can bee seen theat all the circles are
conected.
The image below is a shot of the block from below. It isnt the final image but the step before the final completion of the 3D object.
