## Isolate Strut

### Creating Isolate Struts Sets

1. Select a Primal, Dual or Spaceframe Isolate tab on the Toolbar.
2. Set the Isolate Mode by clicking the Strut button.
3. Click on a strut in the manifold. The Strut Dimension Options window appears:
4. Select an option for calculating the strut length and click “Okay”.
5. Unique struts are printed in the Log along with their respective properties.
6. The Isolate Strut pop-up menu activates with a list of isolate sets. When you select an item from the Isolate menu, only the selected set appears in the view with its respective labels, whilst other sets are hidden.

### Example

The following example uses Isolate Struts on a 6V Icosahedron, Class I, Method 1 breakdown, truncated at the equator. The log gives the required strut dimensions and the quantity in each set:

UNIQUE STRUTS
Scale Factor = 10.000000000
Units = Feet and Inches
TsQEIcosahedron 6V, Class I, Method 1
Primal Lattice
Total struts = 555
Unique Struts = 9
Strut   Quantity     Length
S1 =   [30]          1.625672289 Feet or 19.508067468 Inches.
S2 =   [60]          1.819082546 Feet or 21.828990552 Inches.
S3 =   [30]          1.873834006 Feet or 22.486008072 Inches.
S4 =   [30]          1.904768612 Feet or 22.857223344 Inches.
S5 =   [60]          1.980125742 Feet or 23.761508904 Inches.
S6 =   [90]          2.028196959 Feet or 24.338363508 Inches.
S7 =   [130]         2.059077349 Feet or 24.708928188 Inches.
S8 =   [65]          2.153537301 Feet or 25.842447612 Inches.
S9 =   [60]          2.166282144 Feet or 25.995385728 Inches.

Total struts = 555

When a set is selected in the Isolate Struts popup, only that set is shown in the OpenGL view. Thus it is a trivial matter to determine the overall symmetry of the system and view set locations within the dome:
