With the command PIMPORT (from file) point files that are in ASCII-format, can be imported into the drawing. In this process the Point set is generated automatically.
Please note that landscape gardeners usually maintain the order X, Y, Z, but surveyors on the other side use the order Y, X, Z.
Before importing the points it will be checked whether double points are included in the file. These are points, with identical X- and Y-coordinates. Those entries are not permitted, because at one point of a terrain, there cannot be different heights. If there are doubled points, they will be filtered out automatically. This information is displayed in the tab Import > tab General.
If a lot of double points are listed, this also can be a hint, that a incorrect point format was chosen for this import.
If the point set provides a Point number and imported with the Free format option (see chapter Using the Free Format), these point numbers will be used in the point set.
Point label (Tab Layout): The points can also be labelled with the coordinates of the current coordinate system (UCS-Coordinates). The label is also exported when Data transfer to Excel, to an ASCII- or CSV-file. This function is required, for example, when pegging out with a Leica total station.
In the event that the present point set file is not the specifications of the prefabricated point formats a free import format can also be defined. For this, select in the tab Import > tab General > Point format Free Format and the tab Free Format is opend.
At the first start the file will be analysed and the entries are sorted on the basis of separators (space, tabulator, comma, or semicolon) in the Mode > Columns into the respective columns depending on the selected format.
Provided the point set contains a point number and the column is allocated to the point number (e.g. Format_Standard_IXYZ) these point numbers are applied to the point set.
Another alternative can be found in the option Mode: If Symbol is selected a column can be defined through the field length. This gives the ability to import files in which separators were not used.
For this, mark the column and specify in Range to be imported in the field From Symbol the start value and To Symbol the end value within the row.
Once created format settings can be secured for the following imports.
In the point rows of the ASCII-file the point specifications have to be separated from each other (space, tabulator, comma, or semicolon). Each point is described in a text row. Each point column must contain no more than 255 characters.
The order of coordinates and additional information (e.g. a comment on the point) within the point row is free, but is has to be identical for all point rows to be imported in one process.
At the end of a coordinate row any comment text may follow.
If the comment sits not at the end of a point row, but somewhere within, it has to form a word. The separators mentioned above must not be used in the comment. Apart from that, all other characters can be used in any order.
Example: Point23, Point_23.
