CAD Drawing Software Formats FAQ: Expert Answers for Aesthetic Clinics & Dermatologists

Overview

For medical aesthetic device integration and custom applicator design, understanding which CAD (Computer-Aided Design) file formats are accepted is critical for streamlining the production process. This FAQ addresses the most common technical queries from B2B clinic buyers and dermatologists regarding software compatibility, 3D modeling, and file transfer protocols.

Frequently Asked Questions

Q1: What are the primary CAD software formats accepted for manufacturing?

We primarily accept native file formats from industry-standard software including SolidWorks, AutoCAD, and Autodesk Inventor. Specifically, we work seamlessly with .SLDPRT (SolidWorks), .DWG (AutoCAD), and .STEP files.

Q2: Do you accept universal CAD exchange formats like STEP or IGES?

Yes, we strongly encourage the use of universal exchange formats. We accept .STEP (Standard for the Exchange of Product Data) and .IGES (Initial Graphics Exchange Specification) files, which are crucial for ensuring data integrity when sharing 3D models across different software platforms.

Q3: Is the DXF format acceptable for 2D drawings and laser cutting?

Absolutely. The .DXF (Drawing Exchange Format) is fully accepted and preferred for 2D vector data, specifically for skin-contact part geometry and metal fabrication. This format is universally compatible and ensures high precision for laser cutting and waterjet processes.

Q4: What is the maximum file size limit for CAD submissions?

To ensure efficient transfer and processing, the maximum file size limit is 500 MB for single part files and 1 GB for assemblies. For larger files, we recommend using a compressed folder (.ZIP) or utilizing our secure FTP portal.

Q5: How do I ensure my design is compatible with your manufacturing tolerances?

We recommend including a detailed technical drawing with Geometric Dimensioning and Tolerancing (GD&T) callouts alongside your CAD model. While we accept native tolerancing data, we prefer the inclusion of a supplementary .PDF for verification to prevent miscommunication.

Q6: Do you support the latest versions of SolidWorks and AutoCAD?

We currently support SolidWorks up to version 2025 SP1 and AutoCAD up to version 2026. If your software version is newer, please export the file to a neutral format like .STEP or .IGES to avoid compatibility issues.

Q7: What is the protocol for submitting design revisions?

For revision control, we require the filename to include the revision letter (e.g., Handpiece_v1, Handpiece_v2). Upload the new file to the existing project folder and include a revision table in the .PDF drawing to highlight changes for engineering review.

Q8: Do you accept point cloud data or mesh files (STL) for 3D printing?

While .STL (StereoLithography) files are accepted for rapid prototyping and internal visualization, they are not suitable for CNC machining. For production, we require a surface or solid model. We can assist in converting .STL files into a workable solid model for an additional engineering fee.
