When it comes to design projects, the more information about a job site a designer has, the better decisions will be made to provide an accurate understanding of the situation.
One of the most efficient things to do is to georeference a drawing in order to assign real-world coordinates to it. This may allow a designer to notice potential issues before they arise and avoid costly rework.
Georeferencing is a prerequisite for exploring any other features of Plex-Earth. This process ensures that the drawing is accurately overlaid with existing spatial data without skewing its geometry.
Don't know the coordinate system for your project? Try our custom georeference tool, Quick Georeference.
NOTE: If a drawing is already georeferenced through the GEO command of AutoCAD, there will be no need to do so via Plex-Earth as it automatically recognizes the applied coordinate system. This can be checked by clicking on the Set Georeference button. The built-in coordinates will be displayed as shown. If there is a need to change the current coordinate system, click on Change Georeference Method, to apply a georeferencing system with Plex-Earth.
Select Coordinate System
Go to the Plex-Earth ribbon and on the Project panel, click on "Set Georeference". Alternatively, type PXV_GEO in the command line.
Plex-Earth will ask where the project is located and choose "Use a Coordinate System".
Click on the grid button to proceed on specifying the coordinate system.
Select the country or region, coordinate system and units, then click on the SELECT button at the bottom.
|NOTE: Plex-Earth supports over 3,000 coordinate systems worldwide. In a rare case where a system is not included in the list, please send us an email at firstname.lastname@example.org, with its definition or EPSG code and we will add it for you.|
Afterwards, the selected coordinate system will be displayed as shown below.
If no changes are required, click on OK, and the drawing is now georeferenced.
If you are already working on an existing drawing, there are cases where there will be slight misalignments between the drawing and the coordinates. Plex-Earth has a feature to correct these discrepancies by setting an automatic displacement.
Click on the button below as shown, to proceed.
After clicking on it, specify a source point and a destination point in the drawing. After that, the correction in dx & dy terms will be displayed, as shown below. If there is no need to make any further changes, simply click OK.
You can also clear the displacement by clicking on the dx, dy values, then click on "Clear" in the command line of CAD.
After finishing the georeferencing process, you are now ready to explore all the new features Plex-Earth offers.
We hope that you have found this tutorial on how to georeference your drawing by applying a coordinate system, helpful. Feel free to contact us at email@example.com for any questions you may still have.
