Here is the Dorchester 3D general purpose 3DM to PNG file conversion tool. You will find below the blue Upload a 3DM button which you can click and select the 3DM 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 3DM 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 3DM format cannot be converted and may result in an incomplete conversion.
