start off with a rectangle line or box mesh does not matter. then inset it add depth then do the same for the holes and keep them in sync with each other
step 2 of 14
tur it around and add more depth. i used a script called quad Chamfer for the edges with out using turbo smooth. but its still nice to use it any way
step 3 of 14
the top part was a line rectangle and extrude. then use the quad Chamfer tool to smooth the edges again
step 4 of 14
another cylinder inset the holes and bring in the sides
step 5 of 14
then pile on the iterations if your PC cant handle it in view-port use render iterations
step 6 of 14
a wrench i made from line modeling then took a stat added 10 more end and make a hole by the end of the tool add depth
step 7 of 14
i used helix pro and widened the end of the valve used a cylinder for the middle part punched holes with proboolean
make sure to add turbo smooth before proboolean
step 8 of 14
i drew out in lines a fan blade then changed the pivot point to rotate copies. and pull the back end down before copying
step 9 of 14
and now for the alternator i use a cylinder and got rid of the back smoothed the corners added a shell modifier made holes in it by poly edit not pro Boolean for the inside holes but for the outer holes copy and rotate to back. and used a star with extrude for the inner peace
step 10 of 14
i made this using a hose just did some surgery to the inside. bring the mesh in and smooth the edges
step 11 of 14
now to put every thing in place mane focus is the turbo and alternator and export to fbx and render in keyshot
