How to merge 3MX files
User has models of several areas and wishes to merge the files into a single file for more convenient viewing
Requirements and recommendations
Adjacent 3mx file production
To be merged into a 3mx file, the adjacent 3mx must each have:
SRS: You can select any coordinate system, but this must be the same for all the productions
After launching the first production, go to its Properties tab and look for the Coordinates origin values. The other productions must share the same origin.
To do this, when selecting the same SRS in the following productions, open the advanced options…Then select Custom Origin and enter the same coordinates as used for the first production.
To be able to merge 3MX productions, we also recommend the following:
Once all the productions of the ‘sub’-3mx are completed, carry on to the next section.
2.1 Production folders combination
The first step is to merge the production Windows folders.
For the 2 productions P1 and P2 we have the production folders:
…/Production1/Scene/P1.3mx and …/Production1/Scene/Data
…/Production2/Scene/P2.3mx and …/Production2/Scene/Data
Modify the production data as follows:
2.2 Final 3mx file edition : Merged_Production.3mx
After the fusion, the resulting 3MX file should be as shown below:
Once the 3mx edition is complete, you can Save and close the text editor and open the merged 3mx in ContextCapture Viewer.
This proposed method is a workaround and not the preferred solution for viewing multiple models. Ideally we would recommend that the blocks are merged at the Aerotriangulation stage and a new Reconstruction and Production created.. This method can be used when that option is not possible
