Creating punctual and linear objects
This is probably one of the most frequently used commands, since it allows the user to create both points (symbols) and linear objects at the same time using some smart coordinate stacking technique. This means that coordinates of observed objects can be reused at all times, thus making sure that points that should connect, really connect since the coordinate information is copied.
The upper part of the dialog is used to create the entities, whereas the lower part is used to populate the coordinate stack, or calculate some helper coordinates.
The upper part has different combo boxes:
- Lijn : this list is populated with the contents from the linear objects as specified in the configuration
- Block : this list is populated with the contents from the punctual objects as specified in the configuration
- Info : this list is populated with the contents from the infos as specified in the configuration. If you want to add a new info to this list, press the button with the 3 dots. It will open a keyboard where you can type your new textstring, and it will remain avaible during your drawing session.
The list box 'Coord' displays the current available coordinates. When you set a value for the Block or the Info (different from '_GEEN'), you will notice that the buttons BL and INF are made accesible. If you click the button BL, the selected block will be inserted at the last entry in the 'Coord' list box. If you click the 'INF' button, the selected block will be inserted at the last entry in the 'Coord' list box. You can use the buttons 'U' (up) and 'D' (down) to move up or down in the coordinate list. When changing from one coordinate to another, you'll get some visual feedback in the drawing, so you know where you are. If you click the 'LINE' button, and the 'Lijn' listbox is populated with some linear object different from '_GEEN' a polyline will be created using all points in the 'Coord' listbox. When the line has been created, this 'Coord' listbox will be cleared.
Modifying contents of 'Coord' list box
There are some buttons available to change the contents of the 'Coord' listbox:
- RA : Remove All entries from the list box
- RL : Remove Last entry from the list box
- RS : Remove Selected entry from the list box
Navigating around
There are some buttons available that can be used to zoom or pan the current drawing:
- FOL : Follom me toggle that can be activated from this dialog box as well, so you don't need to set this beforehand on the main toolbar
- PAN = pan in the current drawing
- ZW : Zoom Window
- ZP : Zoom Previous
- RZ : Reset Zoom, this functions resets the zoom so you can continuously zoom in/out comparable to Google Earth/Map using the up or down triangle
Historiek: Coordinate Stack
The lower part of this dialog box is used to populate the coordinate stack (“Historiek”) that can be used at all times. All observed GPS coordinates and all manually specified coordinates can be found/retrieved here.
Any coordinate from this list can be reused and copied to the upper 'Coord' list. This means that you can reuse these coordinates at a later stage. the following operations are available on the coordinate stack:
- RA : Removes All entries from the coordinate stack
- RL : Remove Last entry from the coordinate stack
- RS : Remove Selected entry from the coordinate stack
- CA : Copies All entries from the coordinate stack to the 'Coord' listbox
- CL : Copies Last entry from the coordinate stack to the 'Coord' listbox
- CS : Copies Selected entry from the coordinate stack to the 'Coord' listbox
Use the U (up) and D (down) button to navigate in the coordinate stack and get some visual feedback in the drawing, so you know where you are working.
There are several constructions available that can be used to add (calculate) new coordinates, based on other measured or picked coordinates. To add a coordinate to the coordinate stack, you can use the buttons:
- GPS : coordinate from GPS will be added to 'Historiek' and to 'Coord' list (unless the toggle TMP has been activated. In that case, the coordinate will only be added to the 'Historiek' list).
- MAN : user can specify coordinate manually in the drawing by clicking a point. This coordinate will be added to both 'Historiek' and to 'Coord' list (unless the toggle TMP has been activated. In that case, the coordinate will only be added to the 'Historiek' list).
You can also use existing objects in the drawing, select them and use their coordinates. Therefore, you can use the button 'BST'. It will temporary hide the dialogbox and lets you select objects in the drawing by using window, crossing selection method or by clicking on the entity. All coordinates will be added to the 'Historiek' list box.
Historiek: Constructions and distances
There are also several buttons available to help create new vertices (coordinates) based on previously entered coordinates. Some constructions require a distance, for example to create an orthogonal vertex, or to create a circle… Therefore you can use the button DI or DI2. A new dialog box will open where you can set the distance. Distance is specified in centimeters. The following constructions are available :
- LLL : LoodLijn Links. This will create a new vertex to the left, based on the last 2 points in the coordinate stack and the distance specified in DI
- LLR : LoodLijn Rechts. This will create a new vertex to the right, based on the last 2 points in the coordinate stack and the distance specified in DI
- LLV : LoodLijn Vooruit (of Achteruit). This will extend the line created by the last 2 points in the coordinate stack and the distance specified in DI. If the distance is negative it will make the segment shorter, if the distance is positive, it will make the segment longer.
- GEM : Gemiddele. Adds a new coordiate to the coordinate stack at the mid between the last 2 coordinates in the coordinate stack
- INT : Intersectie. Adds a new coordinate (N) to the coordinate stack. The coordinate is the intersection between 2 lines. Line1 is composed of N-4,N-3, wheras Line2 us composed of N-2 and N-1
- CIR : Intersectie tss 2 cirkesl. Adds a new coordinate (N) to the coordinate stack. The new coordinate is the intersection between 2 circles. The first circle is created using N-2 and distance from DI. The second circle is created using N-1 and distance from DI2. In general there will be 2 possible intersections, but we always use the intersection on the right side of the line created by connecting centerpoint from circle1 with centerpoint from circle2
