CRV3D File

What are CRV3D files and how to open them

Are you having problems opening a CRV3D file or are you simply curious about its contents? We're here to explain the properties of these files and provide you with software that can open or handle your CRV3D files.

What is a CRV3D file?

A .CRV3D file is a Vectric Aspire 3D Drawing file.

Vectric Aspire 3D Drawing files are project files used by Aspire, a design and CNC machining program. They store everything about a job including both 2D design work and 3D model components, along with all CNC toolpaths calculated for cutting. These files allow users to save and later re-open a job exactly as it was, with design, modeling, toolpaths and simulation all intact.

Aspire writes these files. Users begin by defining material size, drawing or importing 2D vectors, then build up 3D components and reliefs. When toolpaths are generated to machine the part, they are saved into the Aspire project file. From then on the file serves as a full snapshot of the job up to that point. These files are only fully compatible with Aspire, not with VCarve or similar programs.

When a file has only 2D vectors and no 3D components, Aspire opens it in its 2D design view. If it contains 3D data, the program shows both the 2D view and a 3D view. Toolpath data - those simulating the cutting process - are also stored so that future edits retain machining strategies. The files often appear in Aspire's included clipart library: for example, panel or shield shapes have CRV3D versions that include the 2D artwork used to generate the 3D model.

Internally these files use the same structure as Microsoft's Compound File Binary format, indicated by the leading bytes D0 CF 11 E0 A1 B1 1A E1. They contain sections labelled for design vectors, model objects, toolpaths, materials, version data, and simulation data among others.

How to open CRV3D files

Important: Different programs may use files with the CRV3D file extension for different purposes, so unless you are sure which format your CRV3D file is, you may need to try a few different programs.

While we have not verified the apps ourselves yet, our users have suggested two different CRV3D openers which you will find listed below.
