What is AutoCAD 3D Mechanical Drawing?




AutoCAD 3D mechanical drawing is the process of creating a three-dimensional representation of a mechanical part or assembly using AutoCAD software. AutoCAD 3D mechanical drawing can help you to visualize your design, check for interferences, perform simulations, and create realistic renderings. You can also export your 3D mechanical drawing as a PDF file for printing or sharing.


How to Create AutoCAD 3D Mechanical Drawing?




To create AutoCAD 3D mechanical drawing, you need to follow these steps:


  • Start a new drawing in AutoCAD and set the units and limits.



  • Create a 2D sketch of your mechanical part or assembly using commands such as LINE, CIRCLE, ARC, POLYGON, etc.



  • Use commands such as EXTRUDE, REVOLVE, SWEEP, LOFT, etc. to convert your 2D sketch into a 3D solid or surface.



  • Use commands such as FILLET, CHAMFER, SHELL, etc. to modify your 3D solid or surface.



  • Use commands such as MOVE, ROTATE, COPY, MIRROR, etc. to position and align your 3D solid or surface.



  • Use commands such as ARRAY, PATTERN, ALIGN, etc. to create multiple copies or instances of your 3D solid or surface.



  • Use commands such as SUBTRACT, UNION, INTERSECT, etc. to combine or separate your 3D solids or surfaces.



  • Use commands such as HIDE, SHADE, RENDER, etc. to change the display mode of your 3D mechanical drawing.



  • Use commands such as DIMENSION, TEXT, LEADER, etc. to add dimensions and annotations to your 3D mechanical drawing.



  • Use commands such as LAYOUT, VIEWPORT, PLOT, etc. to create a layout and print your 3D mechanical drawing.



  • Use commands such as EXPORT or SAVEAS to export your 3D mechanical drawing as a PDF file.
