What is a basic difference between a CAD file and STL file?

Contents

Since CAD files are focused on designing traditional manufacturing, it does not include any information about the inside or outside of a 3D object. An STL file does contain the information about the inside and outside of a model.

What is the difference between CAD and STL?

STL: STL (STereoLithography) is a file format native to the stereolithography CAD software created by 3D Systems. STL files describe only the surface geometry of a three-dimensional object without any representation of color, texture or other common CAD model attributes. …

What is the difference between STL and STEP files?

STL files, or “stereolithography” files, are the standard format for 3D objects, especially for 3D printing. … The primary difference between the two is that STEP files are typically much easier to edit due to the STEP file type being designed specifically for CAD editing purposes.

Which is better IGES or STEP?

Why is STEP better than IGES? STEP is newer technology, where IGES which is older 1990’s technology, that has not been updated in over 20 years. STEP files tend to be solid models, where IGES files are more often surface models, which could have gaps and missing faces.

Which is better STL or OBJ?

STL is the de facto standard in consumer-grade 3D printing.
