Here is the Dorchester 3D general purpose STP to PNG file conversion tool. You will find below the blue Upload a STP button which you can click and select the STP file that you wish to convert. Once you have chosen a file to convert it will be uploaded to our server for processing and conversion into the PNG format.
Once your STP file has been converted we will aim to produce a preview of your final file for you to check prior to the final download of your PNG file.
Please note that our tool will try to convert your file where possible however there may be times where some details of the STP format cannot be converted and may result in an incomplete conversion.
