In this tutorial I will make threaded ACME bolt in AutoCAD 3D, Dimensions for bolt is mentioned in 2D layout as shown below.
Follow steps as I have mentioned and you may view video attached with this tutorial for a clear description of each step, And don't forget to subscribe to my channel if you like my tutorials!!!
Firstly make one cylinder of radius 4 units and height 30 units and other cylinder on top of first cylinder with radius 10 units and height 4 units, then make a helix starting from lowermost point of longer cylinder (cylinder with 30 unit height) with top and bottom radius 4 units 12 number of turns and height 30 units, follow image for detail.
Make a new layer named layer 1 and assign longer cylinder to layer 1 and turn off layer 1.
Insert block of ACME thread into drawing from insert block option of INSERT ribbon, You can download the thread block from here.
Now turn layer 1 on and use subtract from Boolean operations to subtract thread profile from cylinder.
Hope this information help for you!
