Layer can be shortly defined as a set of objects. The basis of layer logic is to group objects. Each layer contains certain objects. These objects are part of the project. The project is created when the layers are overlapped. With layer logic, it is easier to manage, control the project and take measures against possible errors.

Each object is located in a separate layer bearing its own name. For example; columns are in column layer, hatches are in scanning layer. These are default layers and are automatically included in all objects as they are drawn. However, objects do not necessarily have to be in default layers. If you want, you can move it to different layers later or to new layers you add. With the layer settings dialog, you can make adjustments such as opening, closing, locking on layers.

Some layers have sub layers within themselves. Sublayers are available on the Drawing Details tab in the layer settings dialog. Layers with lower layers that are not wanted to be seen in the drawing can be turned off here.
