Trying to visualize your 3D CAD model but it’s far too complex for real-time? Whether you’re working on a VR product visualization for a conference, or creating an AR training simulation, making sure your 3D model is simplified and performant for real-time technology is important.

Native CAD data that comes from engineering departments aren’t designed with marketing visualizations in mind. For 3D designers that want to create immersive and interactive experiences of CAD projects, this means spending time and budget cleaning up native CAD data to improve its performance for real-time. But what is it that makes CAD files so challenging to visualize?

Visualizing CAD data becoming increasingly more difficult

Visualizing CAD models’ with several million polygons and hundreds or thousands of objects is not an easy task. As engineering and architectural models get more complex, file optimization only becomes a bigger problem.

CAD files that are not designed with marketing visualizations in mind contain details that are simply redundant in a visualization and need to be manually removed and optimized.

Aside from that, when creating real-time visualizations in game engines, polygons and triangles are needed. This means that to create an immersive visualization, raw CAD data needs to be converted into game engine compatible file formats like FBX or OBJ.

Going from CAD to FBX/OBJ can result in a host of problems for a 3D model. Lost structures, unorganized hierarchies (missing parents, empty nodes, ungrouped assets etc), and errors in the mesh are some of the issues that 3D modelers need to go in and fix manually.
