Relative search path to isometric templates lost in Plant 3D 2027

hean117 — Mon, 22 Jun 2026 09:43:16 GMT

Since switching to P3D 2027 the search path to our templates for isometrics are not relative anymore when creating a new project from an existing reference project. The search path in the new project is still set to the reference project. This is only a problem in 2027, not older versions.

Is there a new setting somewhere that I can't find?

Hello @hean117

As far as I know it shouldn't happen this way. This can be a bug caused because now collaboration projects also allow iso templates in a folder outside of the project folder. So you should contact Autodesk support, but I haven't been able to reproduce the error on my side, but that might be since it was set up differently. How is the link setup in your template project and how does it look in your v2027 project?

No, I have not yet found a solution for this.

It looks different depending on which version I open our reference project in. When opening in Plant 2026 it looks like this:

The full search path to the iso template is showing. This changes to the correct relative path within the project when creating a new one.

When opening in Plant 2027 it looks like this:

The full path is NOT showing. When creating a new project the path is still pointing to the template in the reference project. This can of course be changed afterwards but the risk of someone messing with the original template unknowingly is quite high.

Ok, I think I've figured out the issue. It has only been since version 2027 that you can keep an iso template in an external location (for collaboration projects). Before version 2027 all iso.dwt's are hosted in the respective isostyle folder - so you should see the 2026 link pop up to the collaboration cache folder (see my screenshot)
https://help.autodesk.com/view/PLNT3D/2027/ENU/?guid=GUID-26681974-1D65-415B-B10A-B9EBB68C3117

In 2026 when uploading a project there is a check that will force you to keep the iso template inside the project folder.

In 2027, if your iso.dwt is coming from inside the project folder / iso style folder - you will only see a truncated version. If your iso.dwt is coming from an external location you will see the .url
There is functionally no change. When you create a new project you either choose an iso.dwt that is local inside your SQLite project before loading it up to ACC, or you later modify it to an external location.

There is no change in existing functionality and no added risk. If you only see iso.dwt it means it is the iso file inside the isostyle folder in your collaboration cache. If you see an url: it means the iso.dwt is held in an external location. the only thing changed is that you don't see the full url, but the relative url based on the location of your isostyle folder.

Your .dwt reference is NOT set to the original location. You can check this by entering 'setup title block' then right click on the 'iso.dwt' tab that is opened and choose 'Open File Location' you will see that the file location opened is the correct one, just like in 2026.
