Disappearing symbols

[Andrew Davies 143]

Morning

 

Just went to make some simple changes to some 2D symbols in a drawing.

 

Opened the file - lots of instances of the same symbol missing.  Edit it in Resource browser and add some geometry to test.  Does not work.  Thumbnail in Resource browser disappears.

 

Restart Vectorworks -they re-appear (with the added test geometry)

Carry on working

 

Lo and behold - a different symbol then refuses to be selected (check layer, check class, check everything) - then also disappears

 

Restart again (10 mins after first re-start) and they re-appear

 

Have changed the settings to Good Performance and Compatibility ( was on good performance) to see if that helps - but I am on a brand new MacBook Pro - and this has happened before.

 

So so so frustrating - what a waste of time- just want to get what I need to get done - done,

 

Any ideas?

 

Andrew

Hmmm... I've had something similar, and thought it was down to a view caching issue. Where the vgm fails to redraw certain things. it thinks it's being efficient but it's skipping bits.

Bit odd that it's localised to one symbol only though, and a different one each time.

in 2019 I had a work-around of inverting the colours in the view, and toggling b&w on and off, which would force a redraw and bring things back

 

so in most cases a toggle on and off would fix that...

but your symbol missing it's thumbnail in the resource browser could be a different issue.

 

See if this toggling helps

Andrew, as you are a UK Service Select customer, please submit the file to our UK tech support team who will be happy to look into it for you. uktech@vectorworks.net.

Thanks Tamsin - I will when I get a mo, but it is very difficult to replicate and happens across files.

 

Thanks RussU - will give that a crack too

Interesting that it is happening across files. But we'd love to help. I'll open a support case and drop you an email.

[Andrew Davies 143]

Great - thanks Tamsin. I will respond.

I can confirm this happening - with both 2d and 2d/3d symbols.

 

The issue is very intermittent and undpredictable. The symbols disappear from the resource browser as well.

 

Although possible, I can't think of what I might have done wrong. Especially not so many times in a row.

 

Andrew/Tamsin, did you ever find out why?

 

I'm running 2020 SP3.1

 

Thanks

Hi

 

I am afraid not - it is one of those tricky problems as it is hard to replicate.

 

Make sure you are on the latest service pack though - that’s the first thing support will say

[JMR 221]

Thanks.

 

The issue is intermittent, but when it occurs it gives you a really weird feeling - "Did I just erase that symbol...I can't have....where did it go?". Until you finally realize it's a bug playing tricks on you.
