Project Setup

Within Tobe Builder, return to the main menu containing your projects and select the Create tab.

Create a new project with the name "YourState-Tutorial6-YourName" e.g. QLD-Tutorial6-Ken

In the Address bar, type "177 Pacific Hwy, North Sydney" and hit enter. This does an address search from arcgis.com and the latitude & longitude of your entered address.

Some models, when created have been created on specific coordinates. ToBe Builder allows these models to generate on these coordinates.

The model used for this example, the model was created in the GDA2020 Zone 56 CRS. We use the web application EPSG.org to convert our Address's lat and long into the Local CRS grid offsets.

Tobe Builders default map is in WGS84 (EPSG 4326), in Australia the Local CRS for Sydney is GDA2020 MGA Zone 56.

​

Finish setting up the scene by experimenting with adding the GIS Services above.

Next Zoom in on 177 Pacific Highway, until your view window looks like this. The last GIS Image layer in the table above includes the NSW cadastre, and the block numbers when zoomed in to a low level. This is a free service provided by NSW.data.gov. All States and Territories typically also make this information available for free as well.

Once you have zoomed into the 177 Pacific Hwy block, next we are going to manually place a BIM into the scene. In this case it is an un-coordinated IFC model of the structure.

This file can be found in the Setup toolbox at

ACC>Tobe Builder Tutorials>Project Files>177 Pacific Highway - Sydney

"2023-P177-DM-ST-00002 (EDITED) (1).IFC"

Before dragging this model into the scene, you must first click the "Override Geolocation" tickbox in the inspector, as this model is not correctly coordinated, and therefore must be placed manually.

Once the model appears in the scene you can use the move and rotate tool to line up the corner of the building with the block. You can swap between move and rotate via the move, rotate and pan icons in the top middle, or via the '1', and '2', hotkeys.

Next we can place the rest of the BIM models from that same folder. All the rest are navisworks cache files (nwc), and these are all georeferenced correctly into the GDA2020 Zone 56 Coordinate Reference System (CRS)

Hence you can multiselct to place, you can select any combination by holding down CTRL, or select all the files between each click by holding down SHIFT, just like window explorer.

Once you have selected a number of the files, you can drag and drop into the scene, and they will begin to be downloaded and loaded into the scene 1 by 1.

The BIM Hierarchy can be used to navigate, hide, and make transparent the BIM models within a scene. Experiment with hiding and showing various parts of the model, you can for example hide the envelope completely, or set it to transparent so that you can more easily see within the structure.

Lastly, hide all except the structural model and ARCH 01, and once again use the move and rotate tools to line up the non-georeferenced model with the georeferenced structure within the ARCH 01 model.

Next we can use the custom hierarchy tool within Tobe Builder to resort the BIM hierarcy via any model properties. For the structural IFC, this model has been conditioned with Project Data Structure (PDS) information, so select the "PDS.Zone Name", and "PDS.SubZone Name" as the two levels.

You can then use the hierarchy to select, hide or later BIM link geometry to tasks.

Lastly we can use the hierarchy to hide the top few floors of the building down to level 22, and then hide the floor slab of that level by selecting, and then clicking the hide selected in the top icons.

Once you have hidden down to level 22, you can select one of the floor beams to create a "Precast Beam" from the model. Once you have 'shift selected' all the parts you need, click the "Create Prefab" button in the bottom action menu, and center the pivot, grab a screen shot, and select 'resource' prefab type.
