How to create 3D padlock in autocad

To create a Padlock, as usual in order to more easily advance we begin by creating a 2D object. Still remember previous tutorials on the use of 'Sweep'? for this moment, we will use it again.

A. Make a 2D object as below, to be able to follow the dimensions of the design or create a new design with the dimensions you want.

Picture 01. Object 2D rectangle

Note:

The object above is the object Rectangle that Fillet on all 4 corners

Then proceed with the drawing to be like this. Do not forget to switch view be 'SW Isometric'.

Picture 02. Patterns help lines sweep

B. Change the object 1 above into 3D with the Extrude command so that it becomes as shown below.

Picture 03. 3D image padlock almost finished

Note:

Extrude height = 50

Left click 'Realistic Visual Style' on the menu 'Visual Style' to see the results of its 3D.

C. Next we turn to the object 2.

When observed object 2 below the line is not yet 'polyline', then we have to make polyline in order for the future can once 'Sweep'.

Do the following:
