MICROSTATION CREATING A PROJECT ACS

Creating an ACS for a project will allow you to rotate the views to suit your project, and also to change the coordinate readout based on a local, site coordinate system should you need to.

In Drawing Aids > ACS > Define an ACS > Define by Points

The first point is the origin of your ACS.

Next, set the X-axis to match the orientation of your project.

An Unnamed ACS will be created. To save it permanently click on Copy ACS and enter a name.

Note: The project will now be physically located at the centre of the DGN file. Other files will still be in the old location, which means the information may not line up when referenced. You either need to reposition the information in every file (which may not be practical) or tell MicroStation to use the coordinates to align your references.

Attaching further references

When attaching additional reference files you will need to make sure that you use Coincident World method to align the global origins.

WARNINGS!

• Never attempt to reposition the Global Origin unless you are 100% sure what you are doing. If you are not sure, always seek expert advice.
• Never reposition the Global Origin without first discussing and testing the implications with the rest of your team and anyone who you wish to exchange CAD files with.
• Always Save Settings after relocating the Global Origin.
• If you agree to reposition the Global Origin, do this in ALL existing project files and the project seedfiles, if your project has them. Mixing Global Origins can cause reference attachment problems, errors when converting to DWG and site co-ordination issues.
