Once you have chosen your preferred online tool, navigate to their website and locate the SLDPRT to your desired format converter. Click on the “Choose Files” button or drag and drop your SLDPRT file into the designated area.

Step 3: Select Output Format

After uploading your file, select the desired output format from the available options. Commonly supported formats include STL (for 3D printing), STEP, IGES, SAT, and more.

Step 4: Convert Your File

Once you have selected the output format, click on the “Convert” or similar button to initiate the conversion process. The time required for conversion may vary depending on factors such as file size and internet speed.
