When we are modeling in AutoCAD, the ability to control object properties is essential. After some hours spent on a new 3D model, we can have hundreds of objects that overlap and obscure the model's visibility. Here are the most important properties.
Freeze/Thaw: In 3D, the density of screen information can be huge. So freezing and unfreezing layers is a permanent process. It's better to freeze the layers than to turn off because objects on frozen layers are not processed (for instance, regenerating or counting for
ZOOMExtents), thus accelerating the 3D process.
Lock/Unlock: It's quite annoying to notice that at an advanced phase of our project, our walls moved and caused several errors. If we need that information visible, the best way to avoid these errors is to lock layers.
Last but not least, the best and the easiest process to assign rendering materials to objects is by layer, so another good point is to apply a correct and detailed layer scheme.
Transparency, as a property for layers or for objects, has been available since Version 2011. Besides its utility for layers, it can also be applied directly to objects. For instance, we may have a layer called 3D-SLAB and just want to see through the upper slab. We can change the objects' transparency with
PROPERTIES (Ctrl + 1).
To see transparencies in the drawing area, the TPY button (on the status bar) must be on.
We select the objects to hide or to isolate (all objects not selected are hidden) and right-click on them. On the cursor menu, we choose Isolate and then:
There is a small lamp icon on the status bar, the second icon from the right. If the lamp is red, it means that there are hidden objects; if it is yellow, all objects are visible:
Shown on the following image is the application of transparency and hide objects to the left wall and the upper slab:
