This is a highly simplified SBS. If you are interested then please contact me and I will make a Solidworks Basics Tutorial.
In this first step I sketched out the shape of the leg in 2D
step 2 of 7
I then used revolves, extrudes and lofts the begin forming the 3D leg
step 3 of 7
This is the completed leg
step 4 of 7
To create the claws I followed the same steps as for the leg. Highlighted in blue you can see the 3 sketches that make up that portion of that loft.
step 5 of 7
The body was a simple shape
step 6 of 7
The mechanical bit in the middle was created as a separate assembly. This is the combination of many individual parts.
step 7 of 7
Final step was to assemble all the parts, apply materials, background and lighting etc.
