How to Convert Orthographic Views to Perspective Views in AutoCAD

Creating orthographic views in AutoCAD is often a straightforward task, especially when accurate dimensions and reference views are available. However, converting those 2D orthographic views into a realistic perspective view can be much more challenging when no 3D model exists.

In this article, we will walk through the step-by-step process of converting orthographic views into the required perspective view using AutoCAD. This approach is especially useful for patent illustrations, technical documentation, and product visualization where an accurate perspective representation is required.

Important: This workflow requires the 3D modeling capabilities available in the full version of AutoCAD. It cannot be performed using AutoCAD LT, as AutoCAD LT does not support 3D solid modeling.

• Create all the required orthographic views in the model space. Save the file as 1st.dwg.

• Open a new dwg file and it as 2nd.dwg.

• In the 2nd.dwg file, in the model space, switch on the ISO PLANE and select ISO PLANE LEFT.

• From the Menu, go to HOME > COORDINATES, select FRONT.

• Copy the front view from the 1st.dwg file and paste it into the model space of the 2nd.dwg file.

• Rotate the WCS icon to perspective view. The required front perspective view is ready.

• From the Menu, click on FILE > EXPORT > OTHER FORMAT. Save the file in METAFILE (wmf) format as name.wmf. Select the required view and save the file.

• Go the the model space of 1st.dwg file. From the Menu, click on FILE > IMPORT, browse the name.wmf file, and place it in the model space.

• Explode the view to edit the lines. Improve the curves and fillets by making minor edits to the view.

• With this front perspective view, you can easily create the 3D front perspective view.

• Similarly, top and side perspective views can be converted from orthographic views into perspective view.
