Direct navigation to objective in-depth evaluation and anti-audit.

Why Do You Need Professional Evaluation?

will contain 3D solids DWG Drawings are imported into mechanical 3D CAD (e.g. SolidWorks, Creo) or for CNC manufacturing (such as Mastercam), It needs to be translated into common STEP (AP203/AP214) or IGES Geometric expression. Ordinary polygon transformations often turn surfaces into rough triangular meshes (Mesh) , Making industrial processing accuracy obsolete.

Enterprise Security & Anti-Piracy Compliance Warning

Mechanical 3D model (such as core mold, machined parts) is the company’s top-secret intellectual property. Perform 3D B-Rep (Boundary Representation) before uploading to the cloud) When converting data, special precautions must be taken to prevent data leakage and loss of trade secrets. For high-precision parts, be sure to use local CAD Conversion plug-in.

Enterprise Data Conversion Best Practices Guide

01

Eliminate two-dimensional projection lines

Before exporting 3D DWG, Delete all 2D outline layouts, Dimension lines and text comments, only pure three-dimensional entities are retained (Solid) To reduce geometric redundancy.

02

Prefer STEP format

STEP The format has more perfect solid assembly structure information than IGES., And it can accurately lock the color of the part and the topological sewing (Sewing) of the surface.

03

Check for tolerance drift

For mating surfaces, please import SolidWorks 'Geometry check'', Prevent tolerance drift (Tolerance Drift) during conversion.

Technical FAQ

Q: What should I do if the converted 3D entity becomes a hollow shell??

This is usually due to the surface mesh used in the original 3D DWG (Mesh/Surface) Instead of solid modeling. If it is a slice import, you need to run'Sew Surface 'command reconstructs hollow surfaces into closed solids.

Q: STEP AP203 What is the difference between AP214 and AP214??

AP203 Only three-dimensional spatial geometric coordinates and structures are retained; AP214 additionally supports color on this basis, Layer definition and complex dimensioning (GD&T). Recommended AP214 Format.
