Abstract: Document spaces are used for intermediate technical documents created for a model with a displayed 3D model view. A document space is a finite volume having a location in the global three-dimensional coordinate system of the model and a reference to a technical document. A displayed document space in the displayed model view illustrates where one or more model parts, or corresponding pieces of model parts, which are included in the technical document, locate.

Abstract: To enable to display one or more drawing content, which have been created during defining one or more engineering drawings from a model which comprises one or more parts to model one or more structures, digital twins of the one or more drawing content with associated information are created and published. The associated information of the digital twin comprises three-dimensional coordinates for the drawing content in question, determined based on one or more parts, to which the drawing content relates, and identifying information of said one or more parts.

Abstract: To facilitate reading out information relating to an object, a drawing is split according to one or more splitting rules to one or more split drawings before it is outputted, a split drawing showing at least one of the objects or one or more pieces of the related information in a way other than it will be shown in the drawing.

Abstract: The present invention relates to a control system for selectively supplying electrical power in a remote environment. The system comprises a plurality of electrical circuits, each designed to operate over a unique frequency passband. Power transmitted within the frequency passband of a circuit is filtered through that circuit to power a corresponding remote device. One or more remote devices can be simultaneously powered by transmitting power within the frequency passbands of the corresponding circuits. It is advantageous to design relatively narrow passbands to accommodate a relatively large number of circuits and corresponding devices for remote operation and a triac, rectifier or other suitable turn-on gate can be incorporated into each circuit to effectively control the width of the frequency passband of each circuit. Alternatively, an operational amplifier could be used.
