Gather project resources:

When setting up a project in cmBuilder, there are three main external inputs to consider:

1. Schedule: You can manually create simulation milestones or import a schedule file from MS Project or Primavera P6 for automatic milestone creation. Supported file types include:

• • Microsoft Project: .mpx, .mpp, .mpd, .xml
  • Primavera P6: .xer, .xml
  • Asta / Powerproject: .pp, .xml
  • Excel and others: .csv, .prx, .stx, .pep, .pod, .fts, .gan, .ppx, .plf, .cdpx, .sp, .gan, .sdef, .schedule_grid, .pc

2. 3D Building Models: You can either use the built-in massing tool for building representation or import a 3D model in IFC, FBX, or STP file format. It's possible to import multiple 3D model files in a single project, where each file can be up to 1.5 GB. The recommended file type and size is IFC 2*3 (<500 MB).

3. Drawings: You can upload site layout or plan drawings to overlay or project onto the map tile using PDF, JPEG, JPG, or PNG formats. Additionally, you can import external satellite or orthomosaic images using the drawing overlay tool.

Bonus: You can also import a single mesh file in GLB format. This feature allows you to import drone scans, your own resource models, and terrain meshes. The map terrain in cmBuilder will drape to the imported mesh that you upload.
