4.1 Geometry Characteristics

4.1.1 Surfaces and Tolerance

4.1.11 Defining a Theoretical SuppLemental Surface. If required, a theoretical supplemental surface shall be indicated with the

words THEORETICAL SIJPPLEM ENTAL SU RF7 as shown in Figures 4-1.4-2.4-3. and 4-4. Any point, line, or surface element within the

model that coincides with a theoretical supplemental surface shall be allowed to vary within the applicable geometric tolerance

applied to the theoretical supplemental surface.

The purpose of specifying a theoretical supplemental surface Is to identify the elements that define the theoretical supplemental

surface within a tolerance zone.

4.1.1.2 Defining Surface Texture. Surface texture, where specified, shall be defined using the requirements from ASME B46.i and

ASME V 14.36.

4.1.2 Bounded Regions and ToLerances. aounded regions may be used to indicate a subset of requirements such as materials,

application ofgeometric tolerances, support structure volumes, allowable attachment areas, and other properties. A bounded region

may be represented as a bounded volume region or a bounded surface region.

The bounded region shall be represented as a separate volume or surface region in the specification for the part. See Figure 4-5

for an example of hounded regions representing volume and surface regions in a single part.

41.2.1 Bounded VoLume Region Identification. If a bounded volume region is required, it shall be indicated by VOLF where Xis a

unique label. The bounded volume region indicator may also be coupled with a feature control frame to specify a geometric tolerance as shown in Figures 4-6, 4-7, and 4-B.

4.1.2.2 Bounded Surface Region Identification. If a bounded surface region is required, it shall be indicated by ‘SURFX” where

Xis a unique label. The bounded surface region indicator may also be coupled with a feature control frame to specif’ a geometric

tolerance as shown in Figure 4.9.
