A dimensioning apparatus for generating a dimensional drawing from a model includes an element database with predetermined element names. A plurality of model elements can be associated with corresponding element names. The apparatus also includes a model sectioning tool operable to section the model to thereby generate at least a portion of the model elements. The apparatus further includes a dimensioning tool with a plurality of predetermined dimension names and a plurality of dimensioning algorithms associated with corresponding dimension names. At least two of the model elements are utilized by each of the dimensioning algorithms to thereby automatically detect dimension values of the model. The dimensioning tool is further operable to associate the detected dimension values with corresponding ones of the dimension names. In addition, the dimensioning apparatus includes a plotting tool operable to output the dimensional drawing showing the dimension values of the model detected by the dimensioning tool.

A vehicle package design system includes a data store of vehicle packages defined in terms of spatial dimensions relating vehicle hard points. A design engine adaptively renders a vehicle space based on a vehicle package, and, in response to user input defining a required change in a target spatial dimension, alters the target spatial dimension according to the required change, and alters one or more potentially altered spatial dimensions based on alteration of the target spatial dimension. A user interface communicates potentially altered spatial dimensions to the user, including indicating them as potentially altered according to alteration of the target spatial dimension. In further aspects, the user interface is adapted to accept user input expressing a desire whether to allow a potentially altered spatial dimension to change, and the design engine preferentially maintains some potentially altered spatial dimensions while altering other potentially altered spatial dimensions based on the expressed preference.

An interference removal system is provided for determining the possible removal of a component from an assembly where the component to be removed is in an environment including other components that interfere with its removal. The system uses dimensional data to define the removal component and its environment including other components. A boundary space is established around the removal component where the boundary space includes another component interfering with removal of the removal component. The removal component then randomly moves within the boundary space until it is free from interference with its environment. The system is intended to assist in automated path planning by removing initial interference conditions.

A virtual reality vehicle simulator has a seat for supporting a person in a sitting position. The person wears goggles that present to the person an image of a virtual vehicle, as well as a virtual image of the person's hand and any objects, such as coffee cups, that the person may grasp in his hand. A position sensing system senses the position of a marker that is attached to a marked portion of the person's hand, e.g., the back of the hand. The person may be tasked to manipulate a virtual object, e.g., a virtual pushbutton, with a contact portion of his hand, e.g., the index finger. To calibrate the distance between the marked and contact portions so that a virtual image of the hand accurately may be displayed, a control surface is positioned adjacent the seat such that the person can manipulate the control surface. Based on the manipulation, the distance between the marked and contact portions is determined, thus calibrating the size of the virtual hand to accurately model the person's actual hand. A plurality of hand configurations can be calibrated by using respective control surfaces, and a virtual image selector element can be manipulated to select which configuration will be presented in the virtual space.
