Frequently Asked Questions

Q: What file formats can I import into Vectorworks when using Ordnance Survey CAD data?
A: The OS-CAD data provided by the UK Map Centre is available in formats like DXF and DWG, which can be imported into Vectorworks. The help guide covers how to bring in these formats properly.

Q: What are the key units and coordinate considerations when importing OS data into Vectorworks?
A: Because OS vector data uses real-world coordinates (e.g., metres) and a defined projection (e.g., National Grid), it’s important to ensure your Vectorworks drawing units match (for example set to metres rather than millimetres) and that the correct coordinate system is used. Otherwise scale or alignment may be off.

Q: Why might the imported map not align correctly or appear distorted?
A: Common reasons include: the drawing units being wrong, an incorrect projection or coordinate system being assumed, the import having been scaled incorrectly, layer order issues, or the OS data extent not matching your site-plan extent. The guide walks through how to check and correct these.

Q: I’ve imported the DWG/DXF file, but the layers are all mixed up or overwhelming. What should I do?
A: OS CAD data often comes layered (e.g., buildings, boundaries, roads) for clarity. In Vectorworks, you can turn layers on/off, hide or freeze those you don’t need, or reorganise them to suit your workflow. The guide may provide suggestions for cleaning up the file for planning or design purposes.

Q: Can I use the imported OS data in Vectorworks for planning submissions or official drawings?
A: Yes - provided you honour the licensing terms (via UK Map Centre as an authorised OS Partner) and ensure the data is correctly referenced, scaled and aligned. Using the correct OS base mapping improves the accuracy and credibility of your drawings.

Q: I’m working at scale (for example 1:500) - how do I ensure that my Vectorworks sheet setup uses the OS data correctly?
A: After importing the OS CAD file, set your Vectorworks sheet layer/viewport scale to match your intended output (e.g., 1:500). Check that the site-plan element aligns with the OS base map, and verify key dimensions (e.g., building edges, site boundaries) to confirm correct scale.

Q: What if the OS data is not in the projection I’m used to - can I still use it in Vectorworks?
A: Yes, but you must ensure that the import process either transforms the data correctly into your drawing’s coordinate system or that your drawing is set up to accept the OS coordinate system. Mismatched projections are a common cause of misalignment.

Q: What’s the difference between using OS raster mapping and OS CAD vector data in Vectorworks?
A: Raster mapping (images) serves as a backdrop and cannot be edited easily; vector CAD data (DXF/DWG) from OS allows you to manipulate, layer, style, and integrate features (roads, boundaries, buildings) in your Vectorworks drawing. The guide focuses on how to import and use the editable vector format.

Q: Who should I contact if I run into trouble importing the OS data into Vectorworks?
A: If you’ve followed the guide and still face issues, you should contact UK Map Centre support. Provide details such as your Vectorworks version, OS data format, drawing units, coordinate system, what you tried and what outcome you obtained - this helps the support team diagnose and advise.
