This article explains how to merge 3MX files into iTwin Capture Modeler.

Background

The user has models in several areas and wants to merge the files into a single file for more convenient viewing.

Steps to follow

For example:

For 2 P1 and P2 productions:
... / Production1 / Scene / P1.3mx and... / Production1 / Scene / Data
... / Production2 / Scene / P2.3mx and... / Production2 / Scene / Data

Combine folders

• Create a directory... / Combined Production / Scene
• In this directory (... / Merge Production / Scene) copy P1.3MX and rename it Merged_Production.3MX
• Copy the two Data folders and rename them Data_1, Data_2

Edit Merged_Production

• Open Merged_Production.3MX in Notepad ++
• Identify the Layers field and copy the P2.3MX description after P1.3MX. Both descriptions are contained in the layer field and separated by a comma.
• Change the root of each layer (from... / Production1 / Scene / Data to... / Fusion Production / Scene / Data_1, Idem for P2)
• Change the name and description of the scene (not mandatory)

Note: this proposed method is a bypass solution and not the preferred solution to display multiple models. Ideally, we recommend that the blocks be merged at the aerotriangulation stage and that a new reconstruction and production be created. This method can be used when this option is not possible.
