To be able to edit an object in the drawing area, it has to be selected first. When an object is selected, its yellow snap points are visible and the object is surrounded by a yellow or purple selection frame. An object is automatically selected when it is placed in the drawing area.

Different colors when selecting objects

When you select an object or a group of objects, there will be different colors of the frame that surrounds the selected object/group of objects.

When one individual object is selected, even if it is in a group, a purple color frames the object.

When a group of objects that are automatically grouped are selected (e.g. walls, panels, components, etc.), a yellow/orange color frames the group.

When a group of objects that you have manually grouped (e.g. disconnected objects) are selected, a blue color frames the group.

When a locked object or group of objects are selected, a gray color frames the object.
