For example, if the expression 0.5*-Blk1WD was applied, the hole would be repositioned in the scene as originally anticipated and a negative value displayed for the D8 parameter on the table. S position on the block’s surface, to the negative side of the plane, the expression must be revised to result in a negative value. Calculation of the expression assigned to the D8 parameter resulted in a positive value, which directed it to be repositioned to the positive side of the face, in its Face Normal direction. If you selected it in the Scene Browser, its yellow sizebox would be displayed relative to the end of the SmartDimension. In actuality, the hole still exists to the left of the block. However, if this expression is applied, the SmartDimension unexpectedly flips to the outside of the block, the hole shape appears to have disappeared, and the Parameter Table now displays a positive value for the D8 parameter. 5*BlkWD1 were entered for this parameter, the expected result of applying it would be to locate the center of the hole shape on the block’s top surface at a distance from the face equal to one-half of the block’s width. The negative parameter value displayed for this SmartDimension (D8) indicates that it is placed ~.756 inches to the negative side of the plane. SmartDimensions placed point-to-plane always orient to the Face Normal direction, or positive side, of the plane. If the parameter in this instance was accessed on the Parameter Table, its value would be expressed as a negative number. The Face Normal direction of a plane can sometimes become an issue in the calculation of expressions in situations where a locked SmartDimension is added between a point and a plane for example, between the center of a hole shape and the side of a block to which it has been added. Parameters not self-contained may be lost in these operations. Parameters that are considered self-contained (parameters that are below the selected shape level) will maintain in operations like copy, catalog, and save as external. The effects of saving to a catalog or file, selected components of a scene that have parameters related to parameters on components that are not included in the save. The effect that the Face Normal direction of planes has on the application of expressions for SmartDimensions between planes and points. Refer to Value Display Considerations in Expressions. Unexpected values may be displayed for applied expressions when current user units are not the same as system units (meters, radians, kilograms). There are a few issues to keep in mind when implementing parameters in part design, such as:
