 +====== Interactive modeling ======
  
 +<WRAP round info 60%>
 +Command: **IMODEL**
 +</​WRAP>​
 +===== Description =====
 +With this tool you can interactively change whole modelings or just single edges within modelings. Possible changes here refer to the Z value (height) of individual edges, as well as the slope ratio of the modeling.
 +===== Procedure =====
 +  - With the right mouse click select the command **Interactive modeling**. The following windows appears:​{{:​produkte:​cad:​dgm:​dgm0064.png?​nolink|}}
 +  - In the top, a list of all existing modelings, in the drawing, including the edges will be shown. If an object is selected, the determined properties are listed below. With the arrow buttons the height and the slope can be changed, where on the right the increment can be selected. The value can be entered directly as well, where the changes will apply by clicking in another field.
 +  - With the option covered the appearance on the screen can be controlled.{{:​produkte:​cad:​dgm:​dgm0063.png?​nolink|}}
 +<WRAP round tip 90%>
 +If an End area volume is located in the DTM object hierarchy, the result of the calculation of the new masses will be displayed in the command line.

 +===== Functions =====
 +|Changing the **height**|The change of heights can be done for individual edges as well as for the entire modeling. If an edge is marked, all settings in the bottom are available. Entering a height can be done directly or by steps. A marked modeling, in which all edges have identical heights the process will be carried out analog an edge. A marked modeling, in which all edges have different heights the field for the direct height input is not available, and the height can be changed with the arrow buttons.|
 +|Change the **slope**|A modeling can only have 1 embankment. For this reason a change in the gradient of the embankment can only happen if at the top of the window a model is marked. The input fields for the slope properties are explained within the command [[Modellierung]] (see Definition of slopes).\\ Changing the gradient of multiple slopes will be edited in modeling in the DTM-Manager.|

 +The interactive modeling is very clear, when previously an isometric view was selected.
 +</​WRAP>​
 +==== Automatic mass balance ====
 +The automatic mass balance is a special form of interactive modeling is the mass balance (on the window **Modeling Editor** > menu **Tools > Mass balance**). This way a modeling can be built into the Surface, that within the End area volume the ratio of cut and fill has a precisely defined rest volume.
 +
 +<WRAP round important 90%>
 +Requirement for the Mass Balance is a modeling and a calculated End area volume.
 +</​WRAP>​
 +=== Mass balance with an end area volume ===
 +On the request that on a site for a project as little earth material as possible should be driven off, it’s a great way to use the automatic Mass Balance. This way the optimal build in height for the modeling can be determined. ​
 +
 +  - After starting the command select the modeling in the left dialog window.{{:​produkte:​cad:​dgm:​dgm0067.png?​nolink|}}\\ \\ 
 +  - Click on the **Tool** tab **> Mass Balance**. Select the End area volume that should be used as a basis for the calculation.\\ {{:​produkte:​cad:​dgm:​dgm0065.png?​nolink|}}\\ \\ 
 +  - In the bottom area the rest volume will be shown. Insert the desired rest volume and the tolerance you want to use. Positive values will create a fill, negative values will create a cut.
 +  - After confirming with **[OK]** the optimal build in height will be calculated and the interactive modeling window will appear again.{{:​produkte:​cad:​dgm:​dgm0066.png?​nolink|}}\\ \\ 
 +  - As basis for the mass balance you also can use single edges from modelings. ​  
 +
 +<WRAP round tip 90%>
 +Due to the precise calculation of the height of the modeling the modeling will be inserted in the Surface with a very high accuracy (more than 16 positions after the decimal point). The result is that the End area volume in some areas can have only a few mm heights, for a later documentation with transverse profiles, this can cause unnecessary numbers of profiles. Therefore fix the height of the modeling to a rounded value. For example: 34.8076171 to 34.81.
 +</​WRAP>​
 +=== Mass balance with multiple modelings ===
 +On the request that on a Terrain the cut of an excavation can be used as fill in another area, the mass balance with multiple modelings should be used.
 +<WRAP round tip 90%>
 +This way only one modeling will be changed, while the other models will not be changed.
 +</​WRAP>​
 +The procedure is the same as creating a mass balance for a modeling. Crucial here is simply what modeling edge is marked, when the mass balance command is used. The selected object is modified and the differences with the other objects will be evened out.
 +
 +In this example the cut of an excavation in a part of the Terrain is deposited, where it was worked with 2 models. The cut of the model 1 excavation will be used as landfill in model 2.
 +

 +{{:​produkte:​cad:​dgm:​dgm0071.png?​nolink|}}
 +
 +Alternatively,​ the task can also be solved with a modeling that contains multiple edges. In this example the cut of the excavation will be deposited in one area, where it was worked with one modeling. The cut in the area forced edge 2 will be used as fill in the area forced edge 1.
