A brand new look and a new modeller kernel empower the modelling capabilities. A measures layer enables the user to visualize and change measures, giving a new dimension in precise and accurate modelling. Adding new modalities like handwriting and speech, GIDes ++ present a natural and intelligent multimodal interface enabling quick models prototyping creation. Visually, much effort is being made to create a more appealing and elegant application, but keeping always in mind the usefulness of these visual effects.Interaction Techniques3D ModelingSketchingGesture InterfacesCalligraphic InterfacesHandwriting RecognitionVoice Recognition.10.2312/pt.20031441167-171
