Most often users want to add a PDF or Microsoft Word document in the SOLIDWORKS Electrical project and collect it within the project archive. This can be done only by adding the document in the document tree.
If there are a limited number of files you would like to add, you can do so by following the steps below:
Right-Click on the Book > New > Click on Data files/Datasheet > Now browse to the PDF or the document you would like to add to the project > select the file.
You will now see this attached file in the document tree on the document manager.
This file will be included in the project archive when the project is archived through File > Project manager > Select the project > Click Archive on the management Tab.
However, if multiple users are using electrical at your company, then you could store all the datasheets in a network location accessible by all users and reference the network location in the part properties.
