1. Important – be sure to read this BEFORE you process your model

Make sure that all the required files are included in the upload:

 

Files	Format	Other specifications
OBJ and MTL Files	Wavefront OBJ
Textures	*.jpg or *.png	Resolution not more than 8192x8192 pixel, not more than 100 pieces
Kameraparameterdatei	ATExport XML
original images	*.jpg or *.png

 

• The camera file must be exported in Block Exchange XML format.
• The textures must always have a power of two as the number of pixels. Here, the highest resolution of a texture may be 8192x8192 pixels. The textures must be in *.jpg or *.png format. The number of textures must not exceed 100.
• Check your camera file (XML) again before uploading. Make sure that all images you want to see in TWINPSECT are present in this camera file. (During the upload your data will be validated again. Again, check the number of images in the validation overview).
• Please read the step by step instructions carefully. The red marked parts are very important and decide about the successful upload of your project.

2. Export your TWINSPECT® model

Export local

Export OBJ

Submit a new ContextCapture production for the 3D mesh in the OBJ wavefront format. See below for the format options. By this, an OBJ file of the model with the corresponding textures will be generated. 

The texture compression is freely selectable.

Make sure that the Spatial Reference System is set to local.

 

Export Camera file

After exporting the model into the OBJ format, export the block properties into a XML file. For this, please click on “Block” - ”Export” - “Export block…” (see screenshot below).

Then, the following dialog will show up. Please select the “ATExport XML format” and click on “Export block”. By this, a new XML file for the block properties will be generated. 

 

Export georeferenced (EPSG)

Export OBJ

Submit a new ContextCapture production for the 3D mesh in the OBJ wavefront format. See below for the format options. By this, an OBJ file of the model with the corresponding textures will be generated. 

The texture compression is freely selectable.

Please enter the correct EPSG code for your project in the "Spatial Reference System" tab.

If you are unsure which EPSG code your project has, please upload an image to https://srs.twinsity.com, copy the EPSG code and paste it into the “Coordinate System” field (unfold and press more).

 

 

Export Camera file

After exporting the model into the OBJ format, export the block properties into a XML file. For this, please click on “Block” - ”Export” - “Export block…” (see screenshot below).

Then, the following dialog will show up. Please select the “ATExport XML format” and click on “Export block”. By this, a new XML file for the block properties will be generated. 

Make sure that the "Spatial reference system" option contains the correct ESPG code for your project.

 

Important:

Make sure that all the required files are included in the upload:

- OBJ files

- MTL files

- textures (must not be larger than 16k. However, 8k is optimal for our program)

- camera file

- original images (*.jpg or *.png format)

4. Upload your TWINSPECT® model

To upload the project to TWINSPECT®, press the "Create" button in our dashboard.

Now there are 5 steps to upload your project:

1. Enter the name of your project, the asset type and choose “Bentley Context Capture” reconsturction software.
2. Under "Select Source Folder", select the folder containing all project data files. Depending on the browser, select "View files" to display the images.                                                                   
   Important: Our upload only works with Google Chrome or Microsoft Edge internet browsers.
3. We validate your data before you can upload the data to avoid any problems. If there are any errors in your data, they will be displayed here.
4. Your project will be uploaded.
5. Your project is uploaded.

When your project is uploaded, you will see it under the "Project Draft" item in our dashboard.

Once the project is finished by us and accessible to you, the model will be displayed under the "Projects" item.
