Large edrawing assemblies really slow and laggy

We have eDrawing viewer on some PC's in the Shop and they can see our Vault (read only)  but there viewer is very choppy and slow.  I'd love to see if you find an answer to this.

I have been disappointed with performance of eDrawing also, so much that I avoid it entirely. I don't even deploy it to new PCs in our business. It is a flawed product. It is unsuitable for professional use. People who do use it likely do not know that alternatives exist. Improving or fixing this product is not a priority for its creators, even though it is sometimes the very first impression of the flawed 3D design software package upon new users, salesmen, business leaders (i.e. decision makers), and other non-designers. I could defecate on it more, but I think you may get the point by now.

Adobe Reader replaces this application entirely.

For viewing 2D drawings, this is very simple and straightforward, and shouldn't need further explanation.

For viewing interactive 3D models, including taking measurements and creating section views on the fly, I use 3D PDFs. Although I know it has been covered before, I cannot find the discussion to link. I'll summarize the issues.

Creating a 3D PDF

     * Save As. Save as type: Adobe Portable Document Format (*.pdf). Then check the box below [√] Save as 3D PDF.

Opening a 3D PDF

     * This must be enabled through Preferences -> 3D & Multimedia -> [√] Enable playing of 3D content.

     * This must be set on every users' installation separately (at least those that will be opening it). It persists.

Interacting with 3D PDF

     * Find a demo on YouTube. I won't elaborate. There are many options and controls for views.

     * A 3D mouse is helpful but not necessary. To use it in Adobe Reader, I had to upgrade the mouse driver.

     * Click one edge or face, then tape measure icon to measure it. Click two entities to measure between them.

Known issues:

     * It doesn't always work. This is always the case when assembly contains a horribly broken and error-filled imported component. If this hinders your use, then do not use horribly broken and error-filled imported components, but rather fix it completely, suppress that item, and/or replace it with an appropriate placeholder component.

     * Very large assemblies are accordingly slow to create, load in viewer, and interact in views. Still, it's way better than eDrawings.

EITHER: Provide your shop users expensive design workstations to merely view eDrawings, or adapt to 3D PDFs on moderately capable PC's, tablets, phones, hololens, cerebral implant, or whatever hand-me-down hardware they use normally.

3D PDFs most notably do not require impressive hardware specs to perform well!

Get used to it.

Solidworks has dropped the ball, the program and the whole idea of making Edrawings useful.

Makes me look silly after recommending it to managers for viewing what projects are looking like.
