What you need to do is create a sample drawing and have the preview updated.

Once the template has been saved with a preview, open drawing again and lock
the preview, delete the sample drawing and save.

There is more details at

The question is number six. Unfortunately, the cleanup portion is missing,
so once the preview is locked, delete the drawing page.

Hi,
I want to create my own .vst template that can reused by others.
It's fine for create one however, when open new drawing .
the template's preview diagram is empty... Square and empty.

I know if I chose to save the .vst file with a default page (for preview
used), contains some diagram.
then the preview can see just like the default page.

but tihs is not what I need, since when use the template, the preview used
default page will also show out. I really dont need this.

any ideals ?

help me again. thanks
