In this article, we'll walk you through the process of creating a 3D model in AutoCAD. We'll be using the modeling tools available in the 3D modeling world space to create a model with 4 parts. This tutorial is designed for those who want to learn how to use these tools effectively. Let's get started!Create the Base PlateThe base plate of your model will serve as the foundation. To create it, switch to the software and create a box. Specify the first corner by clicking on the box tool. Next, choose the length option from the command line, enter the length value (92), press Enter. Repeat for the width (64) and height (60). You should now have created the base plate.Create the First SectionThe slot in this section is where a part will fit. To create it, create a rectangle anywhere on the screen with a length of 20 and width of 60. Create a circle at one end of the rectangle and trim the unwanted parts. Use the join tool to convert all entities into a single entity.Create the Second SectionThe back wall of this section will be parallel to the base plate, but its height will be adjusted based on the first section's slot. To create it, change the UCS position, aligning the XY plane of the UCS to the face you want the wall to be parallel to. Create a rectangle at the back end of the base plate with the specified length (64) and width (48). Use the extrude tool to create this section, ensuring to adjust the height as needed.Create the Third SectionThis section will have a rectangular shape and a cutout. To create it, change the UCS position again, aligning the XY plane of the UCS to the face you want the section to be parallel to. Create a rectangle with the specified dimensions (40 x 28) and use the circle tool to create a circular cutout. Trim away the unwanted parts and join the entities together using the join tool.Create the Fourth SectionThis section will be triangular in shape. To create it, use the polyline tool to sketch out the triangle. Extrude this triangle to the specified height. You can now see your model with all four sections!Combine the SectionsUse the solid union tool to combine all the objects into a single object. And that's it! You have now created a 3D model in AutoCAD using the modeling tools available in the 3D modeling world space.
