When you freeze a layer, the visible effect is the same as turning a layer off. The difference, however, is that when you freeze a layer, AutoCAD releases it from memory. Solution: Make sure that the layer is not current before attempting to freeze it. It is similar to turning off layers or freezing layers through the Layer Properties Manager, but instead of turning them off by name, you select objects on the layer s you wish to freeze.
Test disabling or uninstalling antivirus software. Try restarting the computer in diagnostic mode to disable background processes and allow AutoCAD to run in a clean environment see Use Windows diagnostic mode to troubleshoot Autodesk software issues. Freezing a layer prevents its weights from being modified.
This technique is often used in transfer learning, where the base model trained on some other dataset is frozen. Invisible is invisible BUT selectable!?
You can freeze layers in all viewports, in the current layout viewport, or in new layout viewports as they are created.
Locks and unlocks the layers. You cannot edit objects on a locked layer. Locking a layer is useful if you want to view information on a layer for reference but do not want to edit objects on that layer.
Controls whether the selected layers are plotted. If you turn off plotting for a layer, the objects on that layer are still displayed. Turning off plotting for a layer affects only visible layers in the drawing layers that are on and thawed.
If a layer is set to plot but is currently frozen or off in the drawing, AutoCAD does not plot the layer. Turning off plotting for layers containing reference information such as construction lines can be useful. Freezes selected layers in the current layout viewport. You can freeze or thaw layers in the current viewport without affecting layer visibility in other viewports. In most cases, you may turn layers on and off frequently to control the visibility of objects. But if you do not need to see the objects on a particular layer for an extended period of time while working on a drawing, freeze the layer to improve the overall performance.
There is also one other difference between freezing a layer and simply turning it off. If you attempt to turn off the current layer, the program will ask if you really want to do this, and it is possible to turn off the current layer.
But you cannot freeze the current layer. If you attempt to freeze the current layer, the program will display a warning telling you that you cannot freeze the layer because it is the current layer. The program will not allow you to freeze the current layer. Understanding the Freeze and Thaw Layer States. Learn about using the freeze and thaw layer states in AutoCAD
