Here is our free to use STP to PLY 3D model converter tool that will take your STP file and convert it to the PLY format ready for loading into your favourite 3D modeling package. Our 3D model converter supports batch processing of your files and can convert up to 20 STP files at one time.

Select File(s)

Drag and drop your files here to upload or click the button above.
A maximum of 20 files can be converted at once.

Please note: Your STP file file, when uploaded to our server, will be deleted 15 minutes after upload. Please download your converted STP file file before this time.

The STP to PLY model conversion tool will analyse your STP file and convert its 3D mesh data including vertices, surfaces and where applicable vector normals and texture coordinates to the PLY format whilst maintaining the structural accuracy of your original STP 3D model file.

File information for STP and PLY

Full Name	STEP-File
Extension	STP
Type	3D Model
Mime Type	application/octet-stream
Format	Binary

The STP file format, also known as ISO 10303-21, is a 3D file format used within the area of computer-aided design (CAD) as a way to exchange data between different applications. The STP format is essentially a plain text file containing commands used to describe the 3D object.

Due to the standardized nature of the format, there is support for importing STP files into many CAD applications. STP files can, however, become quite large, and some complex files can take a long time to import into a 3D project.

Mesh Geometry

The STP format is not a mesh-based format; converting a STP file to a mesh format is possible via most CAD applications via a tessellate function.

As materials containing color information is supported by the STP format, our tool will do its best to include this in the converted file.

Full Name	Stanford Triangle Format
Extension	PLY
Type	3D Model/Point Cloud
Mime Type	application/octet-stream
Format	Text

The PLY file format, commonly referred to as the Stanford Triangle Format, is a 3D file format that comes in either plain text or binary formats. The PLY format is a mature format and is supported by many popular 3D editing applications.

Due to its ability to handle full-color 3D point clouds, the format is commonly used as a medium of exchange when working with 3D scanners. There are also many 3D models available online in the PLY format.

Frequently Asked Questions

How do I convert my STP to PLY?

First, click the "Select File" button and choose your STP file. We will upload and convert your STP file. Once the conversion from STP to PLY completes, use the provided link to download your PLY file.

How long does it take to convert my STP file to PLY?

We aim to process all STP to PLY file conversions as soon as possible; this should take around 5 seconds; however, this may be longer for larger files.

Is the STP format suitable for 3D printing?

No. Most 3D printing slicer software will not support the STP format. It is recommended to convert your STP file to the STL format if you wish to 3D print it.
