Geometric Construction Ribbon - Intergraph Smart 3D - Reference Data - Hexagon PPM

For a new geometric construction, you can identify the status of input items by the background color of the step:

- No background color when there is no input.

- Yellow background when an input is selected.

- Blue background when an input was selected for the previous geometric construction. The input can also be used for the current geometric construction.

Selected inputs display highlighted in pink in the Workspace Explorer and as pink dotted lines in the graphic view:

When changing an existing geometric construction to a different definition, colors represent the different value changes:

and - No background color when you keep the value of the original geometric construction.

and - Yellow background when you change a value.

and - Blue background when the software changes a value to a new suggested value.

Projection Method

Specifies how a curve or point is projected on a surface.

Construction

Specifies creation of a construction surface. When defining a seam, a construction surface allows splitting of the surface with ACIS tolerances specified in the software. A construction surface is not needed for a profile.

Extension

Specifies the extension of the curve beyond the selected surface or construction.

Extension at Start

Specifies the extension of the beginning of a curve beyond the selected surface or construction.

Extension at End

Specifies the extension of the end of a curve beyond the selected surface or construction.

Distance

Specifies the distance of a point along a curve relative to the selected coordinate system.

Distance Method

Specifies how a point is measured along a curve.

Distance Direction

Constrains a point to the reference plane or surface in the specified direction.

Side Ambiguity

Specifies the direction to use when point projection has more than one solution. The closest point projection in that direction is used.

Numbered steps have the following usage for Point at Minimum Distance:

• 1 - Selects the coordinate system used for the specified directions and axes.

• 2 - Selects the first plate system or surface.

• 3 - Selects the second plate system or surface.

• 4 - Selects the sketching plane that intersects the selected plate systems or surfaces.

If the same plate systems are also used as boundaries or for sketching in a parent command, you must also specify them as boundaries or add them to Sketch 2D using Add Intersecting Item or Add Projection Item .

Method

Specifies the measurement method. Select one of the following options:

• At girth then along normal - Positions a point at the girth distance from the starting point along the curve of the first plate system (such as the hull), and then at a distance from the girth point along the normal to the curve. The starting point is at the intersection of the first plate system, the second plate system, and the sketching plane. The curve of the first plate system is at the intersection between the first plate system and the sketching plane.

• At intersection of offset curves - Positions a point linearly along the select coordinate system axes from the starting point of the offset curves from the first and second plate systems.

At girth then along normal options

Girth Distance

Defines the girth (see ) distance along the first plate system curve.

Normal Distance

Defines the linear distance normal to the first plate system curve.

Intersection

Defines the axis direction for the intersection point, when the first plate system, second plate system, and sketching plane intersect in more than one location. Select +x, -x, +y, -y, +z, or -z. For example, a hull, deck, and transverse sketching plane intersect on the port and starboard sides. Select +y to use the starboard side starting point or -y to use the port side starting point.

Girth

Defines the axis direction used to orient the girth distance measurement.

Normal

Defines the axis direction used to orient the normal distance measurement.

At intersection of offset curves options

Offset 1 Distance

Defines the linear distance along the first plate system curve offset.

Offset 2 Distance

Defines the linear distance along the second plate system curve offset.

Intersection

Defines the axis direction for the intersection point, when the first plate system, second plate system, and sketching plane intersect in more than one location. Select +x, -x, +y, -y, +z, or -z. For example, a hull, deck, and transverse sketching plane intersect on the port and starboard sides. Select +y to use the starboard side starting point or -y to use the port side starting point.

Offset 1

Defines the axis direction used to orient the first offset measurement.

Offset 2

Defines the axis direction used to orient the second offset measurement.

KeyPoint

Specifies a key point by index number. Every cross-section has 27 key points, although some are combined for cross-sections with simple geometry. For more information, see Key Points.

Select Value in the 3D Graphic View

Allows key point selection in the graphic view. Key points display as preview geometry, key point numbers, and the local u-v coordinate system. For more information, see Key Points.

U Offset

Specifies the offset of the geometric construction point from the key point along the local u-axis of the cross-section.

V Offset

Specifies the offset of the geometric construction point from the key point along the local v-axis of the cross-section.

Auto Preview

Displays a preview of the polyline in the graphic view.

Segments Count

Specifies the number of segments to use to create the polyline.

Category

Specifies the method of segment creation.

Auto Preview

Displays a preview of the corrugated surface in the graphic view.

Category

Specifies a category of corrugation parameters.

Corrugated surfaces have the following parameters:

1

Select the planar cross-section curves that form the boundaries of the surface. These planar curves can be open or closed. They must be oriented in the same direction to avoid the bow-tie effect.

(2)

Optionally, select path curves. These curves do not have to be planar. They do not have to touch the planar curves selected in 1.

1

Select the base curve or base point for the surface.

2

Select the offset curves for the surface. These curves can be open or closed. The curves must be oriented in the same direction to avoid the bow-tie effect.
