 +====== Edit line course ======
  
 +<WRAP round info 60%>
 +Command: **ZEDIT**
 +</​WRAP>​
 +
 +===== Description =====
 +The command **ZEDIT** changes lines, splines, polylines, circles, arcs, and ellipses in regards to their Z-values (heights) where in contrast to the command [[Objekte anheben ⁄ absenken]] not the entire drawing object, but individual areas are edited.
 +
 +In a vector oriented drawing program like AutoCAD a line is defined by a point, a direction, and a distance. In DATAflor CAD a simple line has a starting point, a direction, a length, a grade, as well as an end point. A polyline consists of multiple simple lines, where at the end point of the first line equals the starting point of the second and so forth. In a closed polyline the end point of the last line is also the starting point of the first one.
 +
 +===== Procedure =====
 +  - After entering the command the desired drawing element has to be selected in the drawing. Then the following dialogue opens:\\ {{:​produkte:​cad:​dgm:​dgm0037.png?​nolink|}}\\ \\ 
 +  - In the table all vertex points of the selected drawing elemet are displayed with the following information:​ Point number, height, grade in percent, distance to the projection to the previous point, and distance to the first point. If a point is marked in the table it is displayed automatically in the drawing.\\ \\ <WRAP round tip 85%>
 +The values displayed in the table can be copied to the clipboard with <wrap caps>​Strg</​wrap>​ + C and then inserted into an Editor for printing.</​WRAP>​
 +  - There are now several ways to adjust the height within the object: available options are single, all, and interval. Alternatively,​ the height change can be defined through the input of a slope. ​
 +  - With **[Undo]** the last change is deleted, the dialogue is closed with **[OK]** and the settings are applied instantly to the drawing. ​
 +
 +===== Functions =====
 +|**Point height > Individual**|To change the altitude of an individual point in a drawing element double-click with the left mouse-button on the desired point. A dialogue opens where a new height can be specified for this point.\\ {{:​produkte:​cad:​dgm:​dgm0039.png?​nolink|}}|
 +|**Point height > All**|To change the altitude of all vertex points of a drawing element click the button **[All]** and enter the desired height value.\\ {{:​produkte:​cad:​dgm:​dgm0038.png?​nolink|}}|
 +|**Point height > Intervall**|With **Intervall** in the field **Height** a start and end height can be entered for a contiguous point set, whereat the heights of included points are interpolated.\\ Firstly, mark the start point in the table by mouse-click and then click on the arrow up button to select up-wards or use the arrow down button to select down-wards. The selected range is marked with a green bar on the side.\\ {{:​produkte:​cad:​dgm:​dgm0042.png?​nolink|}}\\ \\ Then open the input dialogue in the field **Height** with **[Intervall]** and enter the new height for the start and end point. When the input is confirmed with OK the percental grade between both points is generated evenly.\\ {{:​produkte:​cad:​dgm:​dgm0040.png?​nolink|}}\\ \\ This option can be used if connection points for start and end point are known.\\ For a closed line course the last and the first point are identical. This requires an additional input for which direction the changes are to be applied, because the changes can be made in both directions.|
 +|**Grade>​ Intervall**|With **[Intervall]** in the field **Grade** a grade between start and end point can be entered for a contiguous point set, whereat the heights of included points are interpolated. The grade can also be negative if it is a fall.\\ Firstly, mark the start point in the table by mouse-click and then click on the arrow up button to select up-wards or use the arrow down button to select down-wards. The selected range is marked with a green bar on the side.\\ Then open the input dialogue in the field **Grade** with **[Intervall]** and enter the new slope for the start and end point. When the input is confirmed with **[OK]** the percental grade between both points is applied. On the basis of this input the points in between are moved to new levels.\\ {{:​produkte:​cad:​dgm:​dgm0041.png?​nolink|}}\\ \\ For a closed line course the last and the first point are identical. This requires an additional input for which direction the changes are to be applied, because the changes can be made in both directions.|
