3D-Office: Creating a custom projection

In some instances, a user may want to create a custom projection for specific jobs. If a custom projection is needed, the user will have to first create the job within 3D-Office. Once the job is created in 3D-Office, the job can then be saved to a *.tp3 file which can then be transferred over to the data collector. That job will contain the custom projection needed to complete the specific project.

3D-Office: Creating a custom projection

Creating a custom projection in 3D-Office

In order to create a custom projection for Pocket 3D, a user must first create the projection in 3D-Office. Currently, XML files cannot be exported from 3D-Office and then imported in Pocket 3D. From 3D-Office, the user then can save the file to a *.tp3 that can be used in Pocket 3D with the custom projection.

  1. To start this process from 3D-Office's ribbon bar, go to Project > Utilities > Custom projection.
  1. Enter the information pertaining to the custom projection.
  2. Click OK when finished.
The custom projection will now be saved within the *.tp3 file. The user will now have to save the *.tp3 file to a thumb drive so that they can transfer it over to the data collector.
  1. From 3D-Office, go to File > Save As.
  1. Save the *.tp3 file to a thumb drive that can then be transferred over to the Topcon > 3DMC folder on the data collector.

Selecting a custom projection in Pocket 3D

Once the *.tp3 file has been transferred from the computer to the data collector, the user will then need to set that as their active project.

  1. From Pocket 3D, go to Data > Project, and then set the *.tp3 file that was created in 3D-Office as the active project.
  1. Once the active project is set, go to Data > Control > Options.
  1. From the Coords. menu, make sure Known projection/datum is selected.
  2. After that is confirmed, select the Proj. tab.
From the Proj. menu, there should be a list of regions that allows you to select the custom projection that was created in 3D-Office.
  1. Select the custom projection from this list.

Once selected, it will be set as the active projection in Pocket 3D. The current project will now run with the custom projection.
