    IDK if this is helpful as I'm on 2012 and just importing not referencing but I've just had an issue with a site which is approx 7km across and objects in supplied dxf would not scale correctly to my existing space. I had to go to 11 figures after decimal to get a perfect fit. I've noticed a lot of this sort of thing in VW over the last ~10 years, It feels like underlying code still in inches too, as many errors come out suggesting an imperial base.

    With 2012 the georeferencing was more limited. With any geometry that spans more than a 5KM radius, you will find that any CAD system struggles with floating point maths. For this reason, we recommend that you keep the geometry close to the internal origin and set the user coordinates to match the real world coordinates of the site. With 2012 this is not a straightforward process. Later versions of Vectorworks include options in the Tools > Origin > User Origin command to set the precise coordinates of the site over the internal origin. There is also a command under the Tools > Origin menu to Center the Drawing on the Internal Origin (while preserving the real world coordinates). This would help you enormously, but with 7KM that will potentially cause problems. 

  2. Actually, I was a little hasty in that pronouncement. It seems that this IS an issue, and I will file a bug report immediately. I don't know that we can get this resolved in SP3 at this stage, but the good news is, there is workaround:


    Here's the workflow I would suggest:

    • Edit Vectorworks Preferences, and on the first tab, uncheck Offset Duplicates.
    • Create the copies using CMD+D/CTRL+D (shortcut for Edit > Duplicate)
    • The duplicates remain selected. 
    • Change their design layer on the Object Info palette.

    I hope that helps.

  3. Here's my high level overview.

    1. Open blank document.
    2. Edit document georeferencing settings and choose the appropriate geographic coordinate system. If you are in the UK, the standard UK templates are automatically set to 27700 which is the geographic coordinate system equivalent to the OS British National Grid. On this dialogue, the coordinates at the top relate to the position of the file's INTERNAL origin, within that coordinate system. In a UK file, we set this to the Greenwich Meridian as a default. This can be changed.
    3. Import the DWG file, but use the checkbox This file contains georeferenced geometry. Click the Advanced button and take a look at the GIS tab - this will confirm that the DWG will be brought into the georeferencing settings set at the document level. Click OK and again to complete the import. 
    4. The geometry will land in the correct place within the GIS system (as long as it was actually created in the correct place in the first place.)
    5. Use the Geoimage tool and draw a rectangle around the site. This will load the imagery associated with the site.
    6. Use the Geolocate tool and click on a location on the site to move the internal origin close to the geometry.
    7. From this point on, X and Y are no longer relevant, and you should use Easting and Northing instead. The GIS Stake tool can be used to report these.
    8. If you want the numbers on the User Coordinate system to match, use Tools > Origin > User Origin. Choose the option to Set the user origin to match the origin of the geographic coordinate system.

    Why might it not work?

    • Your DWG is not created in the same coordinate system as the GIS coordinate system.

  4. Yes, the GIS system uses a Geographic Coordinate System which is different to the X and Y values. You should use Easting and Northing instead. But you can also use Tools > Origin > User Origin and then use the new checkbox to align the User Coordinate System with the Geographic Coordinate System. And make sure you are using SP2 or you won't have the checkbox.


    Essentially, X and Y is a rectilinear system, which requires considerable distortion to represent a curved surface on a flat plane.  Once you introduce GIS, the X and Y is no longer relevant. Northing and Easting is used instead. However, the new checkbox described above aligns the X and Y numbers with this coordinate system.

  5. May seem a random suggestion but...

    Is your file's geometry close to the internal origin? Tools > Origin > Locate Internal Origin.

    If there is a huge distance between the geometry (5KM) and the internal origin, then this can cause strange problems like this.

    Try Tools > Origin > Center Drawing on Internal Origin (you may need to clean up scattered geometry, which can occur if you started with a DWG import).

    Nothing in the file, or any referenced files, should be more than 5KM from the internal origin.

    Same issue here...

    Crashes whenever I set a new viewport then try to render it...

    Re-open the file and the viewport renders fine..


    Same happens if I create a new file....

    I have set Verbose error reports so you should be getting a lot of reports from me the last week or so..''


    I'm a huge fan of RenderWorks... Especially as Artlantis is now so awful to work with..'

    But this is getting frustrating trying to hit deadlines when I have to to keep re-launching VW.


    Actually I found VW 2020 to be the buggiest version I have ever used...

    Hopefully this will be fixed soon... 


    Maybe back to 2019 for a while...



    Have you contacted Tech Support? If you send them the file and the crash logs, they may be able to help you... Crash logs are automatically uploaded yes, but if you have a specific file, with a specific issue, that can be reproduced, the Tech Support team will be able to help you.


  7. The Plant Tag settings are determined by the settings within the document - not saved with the plant itself.

    In your 2020 file, click the Plant tool and then click Plant Tool Preferences on the Tool bar. Here, you can set the defaults you want for the tag.

    Now insert the plants.


    Better still save a template which has the settings you want. Templates store resources, page setup, units, but also store your favourite tool preferences.
