Regel 1: Regel 1:
 +====== Special modelings ======
 +===== Description =====
 +Many tasks of Terrain editing can often only be done through several steps with modeling and multiple edge definitions. The special modelings within the [[Quick-DGM]] summarize these various steps into a single command, and automatically create the modeling. ​
 +\\ \\ 
  
 +===== Landfill / Pit =====
 +==== Description ====
 +With this function a landfill/​pit can be defined with only a height or a reference Surface, which then will be merged into the Terrain with forced edges. This can be used for an, for example, excavation (Base grade below Terrain surface) or a landfill (Base grade above the ground). Requirements are an existing boundary (Embankments for landfill) and at least one Triangulation.
 +==== Procedure ====
 +  - Choose a desired Triangulation (base Surface) in the DTM-Tree, and with the right mouse click select the command **Other tools > Special modelings > Landfill/​Pit**.  ​
 +  - You will be asked to select the outer boundary. The polyline must not be lifted to the Surface beforehand. This will be done automatically with this function. ​
 +  - The following window will appear:\\ {{:​produkte:​cad:​dgm:​dgm0131.png?​nolink|}}\\ \\ In the middle section you can choose if you want to use a **fixed height** or if the reference to a different Terrain surface should be used.\\ If you use a fixed height, the base grade will be even and at one level.\\ If you use a **reference Surface**, the Surface of the grade will be the exact Surface of the reference Surface.\\ In the **slope** section you can set the additional attributes for the embankment.
 +  - After confirming with **[OK]**, the modeling will be created and inserted in the Surface.
 +=== Example ===
 +Surface with a boundary (blue line)\\ {{:​produkte:​cad:​dgm:​dgm0132.gif?​nolink|}}
 +
 +**Pit** with toe of slope 28 m – even grade\\ {{:​produkte:​cad:​dgm:​dgm0133.gif?​nolink|}}
 +
 +**Landfill** with top of slope 40 m – even grade\\ {{:​produkte:​cad:​dgm:​dgm0134.gif?​nolink|}}
 +
 +**Pit** with reference Surface – grade from reference Surface\\ {{:​produkte:​cad:​dgm:​dgm0135.gif?​nolink|}}

 +===== Platform =====
 +==== Description ====
 +With the double edge you can create single or multiple plateaus in a Terrain (for example a square with surrounding stairs or ramps). Requirement is that there are one or more closed polylines, which are raised to the correct fitting heights.
 +==== Procedure ====
 +  - Choose a desired Triangulation in the DTM-Tree, and with the right mouse click select the command **Other tools > Special modelings > Platform**. ​
 +  - The following window will appear:\\ {{:​produkte:​cad:​dgm:​dgm0136.png?​nolink|}}\\ \\ The **end height of offset edges** specifies the height of the new edges, for example with stairs this would be the level difference per step.\\ The **spacing** specifies the offset of the new edges. Default is 0.001 (1mm). This is necessary because edges cannot overlap.\\ With **alignment** you can adjust, whether for each edge a manual value of the direction should be inserted (queried).\\ Alternatively this can be adjusted continuously,​ but a vector direction must be specified, which is then used as a default for all edges. Example 0,-1 means down (X0; Y-1).
 +  - After confirming with **[OK]**, the window will be closed and the desired polylines needs to be selected. If all edges are selected you can confirm the command with either the right mouse click or with  <wrap caps>​**Enter**</​wrap>​ and the modeling will be created.

 +=== Example ===
 +Terrain with boundaries (blue lines)\\ {{:​produkte:​cad:​dgm:​dgm0137.gif?​nolink|}}

 +Square with stairs\\ {{:​produkte:​cad:​dgm:​dgm0138.gif?​nolink|}}

 +===== Congruent break edges (walls) =====
 +==== Description ====
 +With this modeling type the following task can be solved: Within a Terrain there are multiple adjacent Surfaces with different heights, which should be generated as breaking edges.
 +==== Procedure ====
 +  - Sort the border edges into the correct height in the Terrain.
 +  - Choose a desired Triangulation in the DTM-Tree, and with the right mouse click select the command **Other tools > Special modelings > Congruent break edges**.
 +  - Select the desired break edges in the drawing. ​
 +  - If all edges are selected you can confirm the command with either the right mouse click or with <wrap caps>​**Enter**</​wrap>​. A window for the edge definition appears. Confirm with **[OK]**.
 +  - The new modeling will be created and automatically inserted into the Triangulation.
 + 
 +=== Example ===
 +Terrain with adjacent Surfaces (blue lines)\\ {{:​produkte:​cad:​dgm:​dgm0139.gif?​nolink|}}
 +
 +Terrain with related break lines (for example house basement)\\ {{:​produkte:​cad:​dgm:​dgm0140.gif?​nolink|}}
 +
 +Terrain with related break lines (for example wall)\\ {{:​produkte:​cad:​dgm:​dgm0141.gif?​nolink|}}

 +===== Even cut or fill =====
 +==== Description ====
 +This function creates a uniform cut and fill, with specifying a parallel shift, which then merges with the forced edges or break edges in the Terrain. This can be used for example for a layered structure (road construction). Requirement is an existing boundary (closed polyline) and at least one Triangulation. ​
 +==== Procedure ====
 +  - Choose a desired Triangulation (reference Surface) in the DTM-Tree, and with the right mouse click select the command **Other tools > Special modelings > Even cut and fill**.
 +  - You will be asked to select the outer boundary. The polyline must not be lifted to the Surface beforehand. This will be done automatically with this function. ​
 +  - The following window will appear:\\ {{:​produkte:​cad:​dgm:​dgm0145.png?​nolink|}}\\ \\ Above the **name** for the modeling will be entered. In the middle section you can select the edge type **forced edge** or **break edge**.\\ Insert a value for **spacing for parallel moves**.\\ The spacing can be negative as well as positive. The edge type forced edge allows in the Terrain connection the use of the option slope. In the slope section you can set the additional attributes for the embankment.
 +  - After confirming with **[OK]**, the modeling will be created and inserted in the Surface.
 +=== Example ===
 +Terrain with boundaries (blue lines)\\ {{:​produkte:​cad:​dgm:​dgm0146.gif?​nolink|}}
 +
 +Terrain with even cut and fill\\ {{:​produkte:​cad:​dgm:​dgm0147.gif?​nolink|}}
