3D World

4 Edit 3D World manually

Steps: 12 Time: 45 minutes Institution: Tygron Language: English

When you have created a new project, a 3D world is generated automatically based on the available data from the connected open data sources. This is the so called baseline project. The baseline project represents the project case as it is from the start of your scenario planning. You can edit the default 3D world manually and by importing your own data sets. In this part, we explain how to edit the 3D world in the Platform itself. In the 3D world models that are available in the Platform are being used to build the 3D world. Based on the purpose of the building and, for example, the year of construction, a model is picked and placed in the right contour of a building. Sometimes there is not enough information in the data to determine the purpose of the building so a placeholder is used in the 3D world. Or, in real life, the building looks more like one of the other models that are available in the Platform than the one that is generated automatically. Very important to take into account, THERE IS NO UNDO BUTTON IN THE EDITOR. All actions performed in this tutorial will be permanent if you save your project. If you don’t want the preformed actions to be permanent either don’t save your project or immediately change the settings back to the way they were before the actions you will perform. This are some examples of why you want to edit the baseline project manually. Take note that when you edit the baseline project you are working in the CURRENT SITUATION tab.

Preparation: Make sure you have opened your project that is already created.

Step 1

Select the CURRENT SITUATION tab.

Step 2

Hoover over Buildings in the header and select the Show Buildings option in the drop-down menu. Now you see the neighborhoods that are available in the project in the left editor panel.

Step 3

Select on the left panel of the neighborhoods. Now the neighborhood will unfold and show you the different building that is present in that specific neighborhood specified by category by which the models in the Platform are categorized by.

Step 4

Select one of the categories, for example, Market Housing, so all Market Houses that are present in that specific neighborhood in the project will be presented in a list in the left panel. The Market Houses are shown in a list based on the addresses.

Step 5

Select one of the addresses and the 3D world will display the selected Market House.  

Question 1

How many bridges are there on the TU-campus?

Notice that on the right panel the information specifically for the selected building is shown. Here you can edit the information linked to this specific building. In the information tabs, you can find different kinds of information. For example the attributes and details for this single building or the function of this building.

Just select the Details tab and the Category tab to see what kind of information is linked to this building. These are all the specifics that are used in the calculations you will run. For example, how much water can be stored on the roof of this building or does this building have a negative or positive influence on the livability in this neighboorhood. If you change these numbers, which you can, it will only have an effect on this specific building. If you want to change the numbers related to all houses in this category, you need to change them in the Function Values. This is not something we get into now. This will be explained later on in this tutorial. In this part of the tutorial, we go change the function of this specific building.

Question 2

When are the houses of the Theresiastraat ( [16-20] ) constructed? 1998

Step 6

Select Change Function in the right panel. A new screen will pop up in the middle of the editor. Here you can select the new function you want the contour of this building to be filled with.

When you change this function the model will be changed immediately into the new selected function type.

If you open the Details and Category tab now, you will notice the numbers are changed as well because with this other building type also other values are selected that are linked to this other building type.

Now you have changed the function of a building based on the address. It is also possible to select a building form the 3D world so the corresponding credentials will be displayed in the left and rights panel.

Step 7

Select a random building from the 3D world. Notice that the corresponding information Is displayed in the left and right panel. In this example picture, you can see that this building is located in a different neighbourhood than the previous building and it is a different building type.

In this case, we are going to change the number of floors and create a slanting roof of this specific building.

Step 8

A building is build up in one or more section. For more complex buildings that have more than one roof height more sections will be present. In the left panel select Section 1. Notice the information displayed in the right panel has changed and now shows the name of this section, the number of floors and the slanting roof height.

Change the number of floors to double the amount of what it is now. And change the slanting roof height to a different number. In this example, the slanting roof height is 0, which means the roof is flat. If you change that number to for example 4, you will get a slanted roof. If the roof in your project is already slanted, just change it to 0 so you will get a flat roof instead.

Step 9

You can also change the contour of this specific building. When you select Draw Area in the right bottom corner you will get a new menu in the bottom middle panel. Here you can select either add or remove. This will give you the option to add a new part of this specific building somewhere else in the 3D world. Or remove a part of this specific building that is already present. In the 3D world, a grid drawing tool will appear to start your selection. By holding the left mouse button pressed you can drag your mouse over the desired part of the building and area to make a selection. All parts that are green will be changed when you choose to apply your selection. All red parts wont be changed. In the legend, an explanation is given why this cannot be performed and therefore is shown in red. There is no need to deselect the red parts, when you apply your selection, this part will simply not be affected by the created selection.

If you want to start over because your selection didn’t work out as desired, just select Clear selection in the bottom right in the middle panel to start a completely new selection.

Step 10

If you want to change the details or category credentials for an entire category of buildings, so not for one building, in particular, you can change the credentials in the Function Values. Hoover over the buildings option in the header and select the Function Values option in the drop-down menu.

Question 3

When you change the floor height of Poortlandplein 5 to 10m, how tall will the house become?

10m

A new panel will open in the middle of the editor screen. When you maximize the new panel you will get a better overview of all the information present in this panel. Here you see per category all related credentials that are being used for the calculations that are made for the indicators and overlays. By sliding to the right you get even more credentials available.

When you change one of the credentials in this panel, the number for this specific topic for this specific category is changed. That means you can change the credentials for all buildings of this specific building type at once. To make the overview of this table more clear, you can work with the filters.

Step 11

Select the category Normal and the Group filter Water. Now you will get all types of Market Houses that are present in the project and all water related values for this specific category. Now you can change one of the values, for example the water storage for a specific type of Market House, and this number will be used in all calculations related to this specific type of market House.

Step 12

Add a completely new building to the 3D world. Close the Function Values panel and make sure you have selected the Buildings option in the header. Now select Add, in the bottom left corner in the left panel, a new building type will appear in the list in the left panel.

Now, in the right panel, this new building can be changed into the desired function and the name can be changed to keep the list on the left as clear as possible. Again withdraw area the new building can be placed in the 3D world.

If the desired selection is made, just apply the selection and the new building is placed directly.

Now you know all the basics about changing the baseline project manually.

Keep in mind that this is all to make sure the current situation is represented in the best way possible so this can be used for scenario planning and all effects can be calculated properly. For more information about buildings and function values please visit the Tygron Support wiki

Question 4

Create a new old vila on the grass triangle near the dillenburgstraat, what will be the terrainmix of the house?
