Internal shape specifiers

In the Dimension Table Edit dialog, after selecting the geometric type to use, in the Geometric Shape section you can select the geometric shape to use.

Geometric shape

Each item in the Geometric Shape drop-down menu maps to an internal shape code, as shown in the table below. The table also shows the dimensions that each geometric shape type requires; in the Dimension Table Edit Tool dialog, first you define the dimensions that the geometry type requires (see Geometry types), and then you define the additional dimensions that the geometric shape requires.

Symbolic name	Shape code	Additional dimensions
Shape from GDL	0	parameters to GDL
Cylinder	1	diameter
Toroid	2	diameter
Cone	3	diameter, diameter
Flange	4	diameter, thickness
Neck flange	5	flange diameter, neck diameter, thickness
Beam	6n	cross section id number
Plate	7	thickness of plate
(no shape)	8
Eccentric cone	9	diameter, diameter
Oval airduct	10n	wall thickness, width, height

For all geometric shapes, the quantity type of both width and height is always Length.

For geometric shapes other than oval airduct, the quantity type of thickness is always Length.

For beams, the quantity type of cross-section ID is Pieces. The ID values are defined in the "Beam cross-sections" configuration object, as described in Beam cross-sections.

Beam profile

If Geometric Shape is set to the beam shape type, you must also select the beam profile and whether to allow designers to override Dimension Table values with instance parameters.

Each item in the Beam profile drop-down menu maps to an internal profile code, as shown in the table below. The profile code numbers are needed, for example, when defining beam classes, as described in Beam classes.

Profile code	Shape code	Description	Required dimensions
0	60	user defined, nonstandard
1	61	L with equal sides	l – Length t – Thickness
2	62	L with different sides	h – Height w – Width t – Thickness
3	63	L, general	h – Height w – Width th – Thickness in height direction tw –Thickness in width direction
4	64	U	h – Height w – Width th – Thickness in height direction tw –Thickness in width direction
5	65	T	h – Height w – Width th – Thickness in height direction tw –Thickness in width direction
6	66	I	h – Height w – Width th – Thickness in height direction tw –Thickness in width direction
7	67	Square cross-section	l – Length t – Thickness
8	68	Rectangular cross-section	h – Height w – Width t – Thickness
9	69	n-polygon	N – Number of sides d – Diameter
10	610	Double-web I-profile	H – Height of profile Wh – Outside distance between the webs Wu – Width of upper flange Wl – Width of lower flange Th – Web thickness Tu – Thickness of upper flange Tl – Thickness of lower flange
11	611	Non-equal I-profile	H – Height of profile Wu – Width of upper flange Wl – Width of lower flange Th – Web thickness Tu – Thickness of upper flange Tl – Thickness of lower flange

For profiles 67 and 68, the quantity type of t can be Length or Wallt.

For other profiles, the quantity type of t, th and tw must be Length.

The dimensions of the beam profile types are shown below.

Airduct profile

If Geometric Shape is set to the airduct shape type, you must also select the airduct profile.

Each item in the Airduct profile drop-down menu maps to an internal profile code, as shown in the table below.

Symbol	Profile code	Shape code	Description	Required dimensions
	1	101	Oval	Wall thickness, width, height

Measures in Dimension Table

First wall thickness measure = wall thickness.
First length measure = width.
Second length = height.

Note: Round and rounded rectangular ducts are not yet supported.
