Here is the Dorchester 3D 3DM to File 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 the next step is to choose what format you would like your file to be converted to. Once you have selected the target file format for the conversion your file will be uploaded to our servers for porcessing.
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 File 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.
