Structures gone after migration

[Stormbr]

I am migrating from P3D 2016 to 2017 and all specs and catalogs indicated they didn't not require migration. I copied all projects onto another machine and opened a few projects in 2017 that were created in 2016. Most of the dwg so far looked ok but anything with a structure member in it has changed the structure to a path and a shape as follows

The I beams, channels and pipe should look like this:

Any idea why or how to migrate structures? Every project has a structure like these so it would be  pain to fix all of them manually.

Hi @Stormbr,

change your view in the Structure from Line Model (1) to Shape Model (2).

I hope it helps.

Unbelievably simple. Thanks again Hartmut, you saved me a lot of grief.

It seems odd that converting from one version to another would make the structures change models.
