 +====== Documentation options ======
 +===== Reduce documentation =====
 +DATAflor CAD can reduce objects automatically in graphic documentation ([[Strecken]] and [[Flächen]]). This helps to make the end calculation look clearer. Reducing means also that deviations from the exact mass of the drawing objects can occur. The higher the reduction, the greater the possible deviation.
  
 +=== Procedure ===
 +The application of the reduction is usedful when working with outline derivations,​ because the decompostion of arcs can lead to a great deal of pick points.
 +
 +**Example:​** In the example a planting area was detected with the outline derivation. The difference between the exact mass and the reduction is obvious. The tolerance can be reviewed anytime in the tab **Documentation**.

 +
 +=== Method ===
 +The higher the entry for the percentage in the [[Optionen]],​ the more reduced the graphic outcome. A high value can also lead to a greater difference between exact and documented mass. 
 +
 +The reduction operates as follows:
 +
 +When documenting,​ a very simple verification should be aimed at. Therefore, it is determined, which consecutive points may lie on a straight line or an arc. For this, the length of the distance between two points is determined. The entry of the percentage in the Options controls, if point is interpreted as //on a distance// or //on an arc//. The percentage refers to the length of the distance, though.
 +
 +**Example:​** Explanations on the basis of the example (specified value in the Options is 5%): The program determines the distance between point 1 and 2. There are no other points, therefore the calculation is continued. Now, the program determines the direct connection between point 1 and 3. The perpendicular distance from point 2 to the connection line of point 1 and 3 is smaller than 5% of the length. Thus, this point will definitely be suppressed. Then, the program moves on to point 4 and creates a direct connection between point 1 and 4. The perpendicular distance from point 2 and 3 to the connection line of point 1 and 4 is smaller than 5% of the length - etc. The calculation will be continued until a point is further away thatn 5%.
 +
 +In this specific example the points 2 and 3 are suppressed and an arc is calculated.\\ {{:​produkte:​cad:​planung:​doku013.png?​nolink|}}

 +If a documentation is not to be reduced, the value for the maximum deviation for the reduction can be used (see **[[Optionen]]**). ​

 +
 +===== Arc reduction =====
 +For the graphic documentation drawing objects like arcs, rounded polylines, and splines, are reduced with a fixed factor. ​
 +
 +The reduction is used to make the billing clearer. Reduction means also that there can be deviations from the exact mass of the drawing object. The greater the reduction, the greater the possible deviation.
 +
 +----
 +
 +===== Increase point numbers =====
 +DATAflor CAD can increase the point numbers for the graphic documentation of areas automatically. The calculation of 2D and 3D areas can result in very acute triangles. This function is used to make the billing clearer.  ​
 +
 +=== Procedure ===
 +The application of this option is useful when working with elongated areas (eg. streets).
 +
 +**Example:​** In the example a street was detected with the Object-Manager. Due  to the generation of additional pick points the clarity of this documentation can be increased.
 +
 +{{:​produkte:​cad:​planung:​dok0062.gif?​nolink|}}
 +
 +=== Method ===
 +The generation of additional pick points functions as follows: In order to present simple and clear verification very acute triangles should be avoided. For this, the shortest individual distance of the total distance of the area is determined. Then, and other individual distances is compared to the shortest and their ratio is calculated. Accordingly,​ up to 10 points are added to the longer distance.
 +
 +On the basis of these points, usually isoscelese triangles are generated. Trapezoids are only used, when an aspect ratio of 1:2 or smaller is reached.
