Note:

•Treat the cad feature as multiple Points in calculating the geometric center

Move an object Point from its current position to the target feature (either sphere, or general surface, or a DCS circle).  It is optional to move the object point along a direction.

This routine is a move-deviate routine, which is deviating the object points instead of moving the components.

Use Cases:

•Project Point to the closest feature: Apply no direction.

•Project to a target feature along a direction: Set the direction to =1 and apply Type-In to project the point in that direction, or use the target direction.

Input:

•One Object Point is required.

•One Target Feature (surf with mesh) is required.

•Optionally, One Direction can be specified.

•Set String=1 to project point in the given direction for irregular surface (eg Cones)

Output:

•The Object Point will be moved to the target feature. When a direction is specified, Point moves along the direction.

Notes:

•Multi-Points are supported – Object Point moved to Target Point in each pair, or along the optionally specified direction.

•Offsets are supported – The Offset Value (if existing) is applied for each pair.

•Feature distance measure now used to find the closest target position and direction instead of the closest meshed point.

•The object point direction is updated based on the direction of the target point.

This routine adds a delta to the existing diameter. The delta value is taken from a measurement input. This routine is a move-deviate routine, which is deviating the diameter(s) associated with object point(s) instead of moving the component(s).

Input:

•One Center Object Point or Diametrical Feature. One is required.

•One Measurement is required. Make sure the measurement provides the delta value.

Output:

•The diameters associated with Center Object Points or Diametrical Features will be changed by a delta taken from the selected measurement. If an Object Point is a Feature Point and is associated with a Circle, the associated Circle Size will be updated. The feature size (mesh size) is NOT updated when a Feature Point is selected.

Notes:

At least one point is required but multiple points can be used. All points used in the object field will produce the same size. Even when different measurements are added, only the first measurement will be used. All other measurements will be ignored.

This move routine will take measurements at the time the move is executed. This routine does not change any model geometry location.

Input:

•Measurements are required.

•Value - If the user input a value= 1 then the simulation will only collect the data for the builds within the spec limit.

Output:

•The selected measurements will remember the calculated values at the time this move was executed. Please notice that if a measure is used as condition or interference checking in a move after this current move, the measured value will be re-calculated at the last move execution time.

Special rules:

If a TakeMeasValues move is used, the nominal value calculation happens at the move execution.

If multiple TakeMeasValues moves are used for the same measurement, the first TakeMeasValues move will calculate the nominal value for the measurement.

Notes:

The Take-Measure Routine can use most measure types within 3DCS; however, it's not recommended to use the Combination Measure within the Take-Measure routine.

This routine deviates the object features based on the deviation of the target features. The deviation includes both position and size with options. This routine is a move-deviating routine, which is deviating both positions and sizes associated with object features instead of moving the components (Move Parts.)

Input:

Object Features: At least one object feature is required.

Target Features: At lease one target feature is required. (Needs the same amount of points that is in the Object Features list to deviate the points in Object Features list).

Values:

oFirst Value: Position Scale - Can be positive, negative, or zero. When Position Scale is zero, no action is taken for the position deviation.

oSecond Value:  Size Scale - Can be positive, negative, or zero. When Size Scale is zero, no action is taken for the size deviation.

oThird Value: Target Calculation Flag - Can be 0 or 1. Indicates whether the target position and size should be combined or not. If Target Calculation Flag is zero (default), the target positions and sizes are averaged and applied on the object features. If Target Calculation Flag is 1, the target positions and sizes are applied by pairing each target and object feature with the same index.

Output:

•The object feature position will be deviated by the target feature deviation with the Position-Scale if Position-Scale is non-zero.

•The object size will be deviated by the target feature size deviation with the Size-Scale if Size-Scale is non-zero.

•The routine only functions properly after the nominal build to get the correct target nominal positions and sizes.

•If multiple target features are selected:

o(1) When the target-calculation-flag is zero, the average values (position or size) are used.

o(2) When the target-calculation-flag is 1, the deviation of target position and size will be applied on the paired object feature with the same index. If an object feature or a target feature is not a feature-of-size, the size deviation will be ignored.

This routine identifies the closest position on two features (surface or edge) using two points. (Relocated from dcu_constraint.dll) The routine is used for translating a slider in touch with a cam.

Input:

•Object Features: Require two coordinate points.

•Target Features require two features.

•Direction: One direction is optional. When a direction is added, this routine will use the direction to project the points to the closest surface.

•Value or Constant:

oThe user will need to specify how many features will correspond to the first feature in the Object list. For example, if the Value1 = 3, the first set of 3 surfaces in the Target list will correspond to the first feature in the Object part. The rest of features will correspond to the second feature.

oIf no Value is applied, or if the Value = 0, this will automatically correspond the first feature in the Target list with the first feature in Object list by default.

Output:

•The point Point1 is located to the closest position on Feature1; the point Point2 is located to the closest position on Feature2.  If the selected features interfere, the points will move to the estimated maximum amount of interference.  The estimate is the same as the one used by the Feature measure.

Output:

•The point Point1 is located to the closest position on Feature1; the point Point2 is located to the closest position on Feature2. The closest is calculated between Feature1 and Feature2 by rotating at the Rotating Center around the Rotating Axis.

This routine is designed as a Tolerance to scale the selected features relative to a center plane. It is closely related with Arc Tolerance with Mag as scaling. This routine can be used to simulate the thermal shrinkage and warping (e.g. heat is on a plane).  KEY: CNTSCALE, CENTERSCALE

User Input:

•Features are required (Support Mesh Nodes or Points)

•One Center feature is required as Reference Plane which provides the Reference Center Plane and Main Scaling Direction

•Optional One Direction; Default Main DIR = Center Associated DIR

oRange - the number shown in the Range field - in the analysis results this number is multiplied by the Distance from the point to the Center Plane or Center Point (if no Scale is applied).

oOffset - is a number representing the  distance from the point to the Center Plane or Center Point. Offset of 1 is the entire distance.

•One Random Value (entered under Constants) is required if Scaling is applied but Scale is optional.

oYou can add a Scale for each direction; once you add a scale there will be a deviation along the scaled direction. The Min and Max numbers in the Analysis window are calculated by multiplying the Range x Distance (from the Center Plane/Point) x Scale.
