possible sublayers? I don't know...

[llgt633]

Win10, QCAD 3.24.0.0. I am VERY new to QCAD!

I inherited this file and have been keeping it up. The project started about 7 years ago using AutoCAD (various versions & several people), and for the last 3-4 years, I've been updating using Draftsight 2D (free version). I've moved the .dwg to QCAD dxf to continue updating.

My example: layer TREES_ORIGINAL do not show when ONLY that layer is displayed. When Layer '0' is 'hidden', the TREES do not display.
When I toggle view off Layer "0", many things are hidden that I assumed would be on different layers. When I select an entity that I thought was on a different layer ie. TREES, Property Manager SAYS tha entity is on layer TREES, but TREES layer doesn't display when all others but TREES are turned off.

Is this a possible sublayer? How can I tell what is a sublayer?
FYI - I didn't buy the E-Book.

QCAD Pro is able to read and write dwg.

No, there are no sublayer in your drawing.

- My example: layer TREES_ORIGINAL do not show when ONLY that layer is displayed.
- When Layer '0' is 'hidden', the TREES do not display.

Incorrect. The content of that layer are only trees. Those trees are inserted from a block (A$C257D5B13). This block is using layer 0 (what is good) for the content. Is layer TREES_ORIGINAL visible and everything else invisible you can see the trees.

The "things" are hidden because there are drawn directly on layer 0.

To see both layer switch layer 0 and layer TREES_ORIGINAL visible ...

This drawing started pretty good regarding the layer structure. But it looks like somebody lost over the time interest in that structure and placed a lot of "things" without any further organization on layer 0. Maybe you are now the right man/woman to fix that .....
