I recently told you about CivilCAD, an application that runs on AutoCAD and also on Bricscad; this time I want to show you how to generate the coordinate table, just As we saw it with Microstation Geographics (Now Bentley Map). Usually these things GIS programs have it With a lot of practicality, but at CAD level it is still a can, because although they are generated they must be done vectorially, losing the dynamic and requiring some editing touches.
There are two options in CivilCAD: UTM and Geographic coordinates.
1. Georeferencing the CAD file.
As we have Explained before
, The fact that the measurement is in UTM coordinates Does not mean that it is georeferenced, since the same coordinates are repeated in other zones, so for that you have to define in which zone you are working.
This is done with: CivilCAD> Change variables.
Likewise, in order to generate geographic coordinates, we will define the properties of the ellipsoid, in case they are different from the one already configured GRS80 / WGS84:
- UTM Zone
- Upper half-axle length
- Area Width (degrees), usually 6
- This false, usually 500,000
- Reverse Crush Coefficient
- Central scale factor
- Longitude of the central meridian, this is the meridian that is to the center of the zone
- North false.
2. UTM Coordinate Grid
For this, it is selected from the menu CivilCAD, reticle and then UTM; or the command manually -RETUTM, then enter.
In the command line the message of selecting the box of our interest appears, then two corners of the zone to label are selected. It is advisable to have the snap activated, so that the lines exactly match the border, the snap is activated or deactivated with the F3 keypad function.
Then the message appears of how far we are interested in the reticle; in this case I'm going to choose 200. And there we have it, simple, without so much complication although with less options as Microstation does.
To change the color of text or crossbars, it is done by changing it in the layers generated in this process; CVL_RETUTM and CVL_RET_TX. In order not to soil the model, this should be done on the layout.
3. Geographical coordinates grid
For this, we choose the second option, or the command -RETGPS and we respond to what it asks (Distance between dimensions in seconds)
To resize text, it is done with: CivilCAD> Text> Define text height.
Single beds, which Civil3D Should do without much return.
