2D-3D CAD Transformations and Design Interaction

2D-3D CAD Transformations and Design Interaction

I want to continue the topic of design interaction started in my CAD and Design Interaction: 50 years in 3 videos post. CAD software started as a vision to replace drawing board and, eventually, it was 2D. 3D CAD and the vision of 3D design came later in the game. It wasn’t simple to create 3D objects in first 3D wireframe CAD packages. Solid feature parametric modeling was a huge innovation open a new page in 3D design and design interaction. However, I can see a new trend – we can re-create 3D objects from physical objects and / or photographs of physical objects. To have an easy way to recreate 3D objects can increase the level of adoption of 3D design software. Until now, my only experience in this field was Autodesk 123d Catch.

By itself, it is an amazing tool to create 3D objects. However, if you’ve been listening to startup pitches, you probably familiar with the phrase “there is a better way”. From Huff post publication few days ago, I learned about Israeli company 3-sweep claiming they can create 3D objects from a single 2D photo by making only few selections. Watch the video. It is cool and impressive.

Here is how founders of the company defines their approach:

“Our approach combines the cognitive abilities of humans with the computational accuracy of the machine to solve this problem. Our technique provides the user the means to quickly create editable 3D parts– human assistance implicitly segments a complex object into its components, and positions them in space.”

Read another article from Singularity Hub. Here is an interesting passage confirming the intent of 3-Sweep technologies:

Ariel Shamir, of the Interdisciplinary Center at Herzliya, and Daniel Cohen-Or and Tao Chen of Tel Aviv University hope to knock that barrier down with software they’ve developed that allows the user to extract the beginnings of a 3-D model of an object from a single photograph. “The key idea is that you could create 3D objects based only on single images,” Shamir told Singularity Hub. “We wanted a model that would be simple for almost anyone to use.”

What is my conclusion? The debates about moving from 2D into 3D are already couple of decades long and jury is still out. In last few years 3D scanning became an interesting trend. While price of 3D scanners is going down together with 3D printers, the opportunity of 3D object creation from existing physical objects becomes real. However, the size is still matter. Also, it is not always possible to scan a physical object. The ability to recreate 3D objects from simple 2D photos can revolutionize design process by bringing another way to interact and design objects. Just my thoughts…

Best, Oleg
