Hi All, I am a new user utilizing Microstation with Terrasolid.
When I import my LIDAR files which are in a coordinate system which I have also added using ESPG reference code.
When I load the points I get an error message saying " Loading may have caused a loss of precision" Input file has a resolution of 1000, Define coordinate setup is set to 100"
The pointsload fine but I cannot see them as once I fit view they obviously become very small..
For the life of me I cannot seem to find a way to change the correct thing.
When we did our training on an older version there was an icon which allowed the trainer to set the approximate values for the X and Y. Can anyone help me with where this option might be in the latest Connect version of Microstation please?
Thanks
Andy
Try checking under the "utilities" tab on the top ribbon interface. once you click it you should see a "coordinate system button," which looks like a globe. once that opens try the icon that says" reprojection settings." Hope this helps!
Hi
You can find a solution in this link

Define Coordinate Setup
Define Coordinate Setup tool sets up coordinate system values that a Terra Application uses for laser points and images. It determines the coordinate range inside which all data must be located and the resolution to which coordinate values are rounded. The coordinate setup is stored into the active CAD file and is used by all Terra Applications.
Terra Applications use signed 32 bit integer values for storing coordinates of laser points and images. This has the advantage of using only 12 bytes of memory for the coordinate information of each point. You can control how accurately coordinate values are stored by defining how big each integer step is.
If, for example, one integer step is equal to one millimeter, all coordinate values are rounded to the closest millimeter. At the same time it would impose a limitation on how far apart points can be or how big the coordinate ranges are. Millimeter steps produce a coordinate cube which has a size of 232 millimeters or 4294967.296 meters. If the origin of the coordinate system is at [0.0, 0.0, 0.0], the coordinate ranges are limited to values between -2147483 and +2147483. If necessary, you can fit the coordinate ranges to your data by modifying the Easting and Northing coordinates of the coordinate system origin.
If one integer step is equal to one centimeter, the coordinate values can range from -21 million to +21 million which is large enough for most coordinate systems.
To define the coordinate setup:
1. Select the Define Coordinate Setup tool.
This opens the Define Coordinate Setup dialog:
2. Define settings and click OK.
This modifies the coordinate system values used by all Terra Applications in the active CAD file
