VW has eaten my Layer ...

[zoomer]

Today I opened VW 2015 SP4 with my current File.

The whole Layer called "BA_1" that I worked on yesterday disappeared.

The Finder Preview image shows exactly all the geometry of that Layer.

Before I saved the file for the last time I exported DXF's per Layer and

there is a "BA_1.dxf"

What makes me really nervous is that this Layer doesn't appear in ANY

backup, as if it never existed !

I checked my 2 VW Backup files, also the Time Machine Backups.

All backup files show the Layers Geometry in a nice Open GL Finder Preview image.

That Layer contained some cubes/building parts added together, thought to be a

"Generic Solid". With some Cubes cut out to fake windows.

Maybe that it got a again "Solid Subtraction" because of subtractions or use of the

Push Pull Tool (which does no more convert to "Generic Solids" but "Solid Addition"

when pulled outwards since SP 4?)

Plus some 2D Rectangles in the window cuts for faking glass.

Beside that and some other (Generic) Solids and 3D/2D Polygon geometry it contains

a larger DTM Model and a backup copy of it.

Meanwhile I rebuild the geometry by importing the DXF.

But am still shocked what funny things VW is often presenting to me before deadlines.

It may not be VW

?

You mean that I could have deleted the Layer accidentally by myself ?

The last file save date and the creation date of the DXF export,

containing all data, are within the same minute/time.

How do you explain that all Backup Files until 4 hours before do

not contain that Layer ?

Everything was fine with that Layer until I closed VW last night and

reopened it today

I assure that Layer and Geometry is still somewhere in the file.

VW just thinks that it should no more be available for users.

The reason may be something that I can't know and would not accept anyway.

Things like the "_" in the file name or that the same name is already used by

a Class or that "BA_1" means something unpolite for VW and it censors it, ...
