Can one use material from more than one SU model in a LO document?

I created one SU model of a pavilion and another for structural members of the pavilion. Now I’d like to draw from both models to create construction documents in Layout. All I’ve managed so far is to create two separate Layout documents. My goal is to export from Layout a single PDF containing the entire set of construction documents.

My experience. I have been able to insert two models into one layout document so that I can draw from both. One was my design model and the other was the structural model. Each model has its own set of scenes. Next, there are free programs online that let you merge pdfs so you could create a single set of pdfs for the construction drawings. I am sure someone on here may have an easier way.

How did you insert two?

In LayOut … File > Insert

You can Insert as many different SKP [and other insert-able content] Files into your Layout document as you wish.
Of course, you will need to reload them whenever there are changes in the SKPs.
Once you have a LO file to your liking you can export it to PDF as a single multi-page document - the page range etc is adjustable…
Alternatively get a PDF-printer [e.g. PDF995] and print to that.
If you have several separate PDF files for pages you can merge them using various free-ware, or on-line sites - e.g. https://www.sejda.com/ or http://www.pdfpi.com/ - some have better file-size limits…

Thanks Geo, TIG.

Insert > file is working like a charm.

I really must re-study LO basics.
