From this autocad tutorial, one can learn how to create a 3d model out of a 2D drawing.
With the help of circle command available in draw panel of home tab, produce some circles. Ensure circle having radius 2.5 units retains its center on the perimeter of the circle with radius 26 units.
Choose polar array from the modify panel available in home tab and opt for two small circles on the top of the geometry. Now, define the center of the largest circle like the center of the array and enter 4 in the number of items field. An array will be produced as follow :-
Remove the largest circle and choose FILLET command, now provide R on the command section and as fillet radius give 7. Now, use this fillet at the junctures of the circle with R2.5 and R22.5 as illustrated below :-
Trim all the geometries so that it appears as follow :-
Write J on the command box and press enter then choose the entire geometry and further press enter to combine all outer 2D segments into a single unit. If it…
