How to Export CADWorx Element to Solid? The Ultimate Guide

Learn ​how to export CADWorx element to solid with this ultimate guide, step-by-step methods, troubleshooting tips, and expert insights.

If you’ve ever wrestled with CADWorx trying to export elements into solid models, you’re not alone. I’ve been there too, spending hours searching for the perfect solution, only to find fragmented advice scattered across the internet. So, after extensive research and hands-on experimentation, I’ve put together the ultimate guide to help you export CADWorx elements to solids with ease.

This isn’t just another generic tutorial. It’s a deep dive into the most effective strategies, including practical tips, troubleshooting solutions, and insights that go beyond the basics. Whether you’re working on a major industrial project or just trying to refine your CAD workflow, you’ll find everything you need right here.

Why Exporting CADWorx Elements to Solids Can Be a Headache

Before we dive into the solutions, let’s address the elephant in the room, why is this even a challenge?

CADWorx is fantastic for designing process plant models, but when it comes to interoperability, things can get tricky. Unlike generic AutoCAD objects, CADWorx elements are intelligent, they contain metadata, specifications, and constraints that can make direct conversion to solids difficult. Exporting these elements incorrectly can lead to missing parts, distorted geometry, or a loss of key attributes.

For me, the struggle started when I needed to transfer CADWorx models into another platform without losing their integrity. That’s when I realized that choosing the right method wasn’t just a convenience, it was a necessity. Let’s explore your best options.

Method 1: Using the EXPORTTOAUTOCAD Command (Quick & Easy)

If you need a fast and straightforward way to convert CADWorx elements into solid models, this is it. The EXPORTTOAUTOCAD command strips the intelligence from CADWorx objects and turns them into standard AutoCAD solids.

Steps:

1. Open your CADWorx model in AutoCAD.
2. Type EXPORTTOAUTOCAD into the command line and press Enter.
3. Choose your desired location and file format.
4. Save the file and reopen it in AutoCAD to verify the conversion.

When to Use This Method:

• When you need a quick export without extra customization.
• When you want to retain as much geometry as possible without CADWorx intelligence.
• If you’re sharing the model with someone who doesn’t use CADWorx.

Limitations:

• Some detailed metadata may not transfer.
• If the model is complex, minor distortions can occur.

I’ve personally used this method in cases where I needed to share files with colleagues using software that didn’t support CADWorx natively. While it’s not always perfect, it’s an excellent starting point.

Method 2: Converting CADWorx Models to 3D Solids Using CONVERTSOLID

This method is slightly more advanced but offers better control over the conversion process.

Steps:

1. Open your CADWorx drawing.
2. Type CONVERTSOLID in the command line and press Enter.
3. Select the CADWorx elements you wish to convert.
4. Press Enter again to finalize the conversion.

Best Use Cases:

• When you need better solid accuracy compared to EXPORTTOAUTOCAD.
• If your model consists of complex piping and fittings.
• If you’re planning to modify the solid model post-export.

Challenges & Fixes:

• Some objects may not convert properly. Try exploding the elements first.
• Converted solids may appear in wireframe mode. Change the visual style to “Shaded” for better visualization.

One time, I had to export an intricate piping system, and EXPORTTOAUTOCAD left me with incomplete geometry. CONVERTSOLID saved the day by ensuring everything transferred correctly.

Method 3: Exporting CADWorx Models to STEP/STP Format

For maximum compatibility, exporting your model as a STEP (.stp) file is an excellent approach. Many CAD platforms accept STEP files, making them ideal for collaboration.

Steps:

1. Open your drawing in AutoCAD.
2. Type EXPORT and press Enter.
3. In the file type dropdown, select STEP.
4. Choose your desired location and save the file.

Why Choose STEP?

• Maintains high geometric accuracy.
• Supports cross-platform compatibility (SolidWorks, Inventor, etc.).
• Retains assembly structures better than DWG exports.

This method has been a lifesaver when working with engineering teams using different CAD software. It ensures the least amount of translation errors.

Method 4: Converting CADWorx Specifications for AutoCAD Plant 3D

If your workflow involves AutoCAD Plant 3D, you might need to convert CADWorx specifications into a usable format.

Steps to Convert CADWorx Specs:

1. Open AutoCAD Plant 3D Spec Editor.
2. Go to File > Convert > CADWorx Specs.
3. Select the .spc file and follow the prompts.
4. Save and integrate the converted spec into your Plant 3D project.

This is a crucial step for maintaining spec integrity when shifting between platforms.

Method 5: Using Third-Party Conversion Tools

Sometimes, built-in tools aren’t enough. That’s where third-party solutions come in.

Best Third-Party Tools:

• CAD Exchanger – Great for converting CADWorx to multiple formats including STEP.
• TransMagic – A powerful tool for high-fidelity model translation.
• Autodesk Forge – If you need cloud-based conversion and API integration.

I’ve used CAD Exchanger in cases where direct exports failed, and it did a stellar job preserving details.

Common Issues & Troubleshooting

Even with the best methods, things don’t always go smoothly. Here are common problems and how to fix them:

1. Objects Disappear After Export

• Check if they are on a frozen or hidden layer.
• Ensure the visual style is set to “Shaded”.

2. Exported Solids Have Missing Features

• Use EXPLODE before exporting.
• Try a different export format like STEP.

3. File Size is Too Large

• Remove unnecessary constraints and annotations.
• Use the PURGE command to clean up the drawing.

Key Takeaways

The best method depends on your specific needs:

• Need a quick fix? Use EXPORTTOAUTOCAD.
• Want better accuracy? Try CONVERTSOLID.
• Collaborating with other CAD software? Export as STEP.
• Working with AutoCAD Plant 3D? Convert CADWorx specs.

Whichever method you choose, understanding the why behind the process will help you navigate challenges more effectively. If you’ve faced any unique roadblocks while exporting CADWorx elements, I’d love to hear about them in the comments. Let’s refine these processes together.
