3.1.1.6.4.8.1. Topology search: Simple search with "Any parameter"

"Topology search" dialog box

The Topology search is a completely new way to search geometrically. This is not a "rough" search as with the geometric search. Special attributes and (optionally) specific values are searched for.

Such Attributes are:

Any parameter
Size	Volume
	Surface
	Largest dimension
	Middle dimension
	Shortest dimension
Symmetry	Axis symmetry (symmetric, nearly symmetric, not symmetric)
	Rotation symmetry
	Plane symmetry
Boreholes	Number of boreholes
	Number of boreholes with diameter in range
Inner cylinders	Number of inner cylinders
	Number of inner cylinders with diameter
Outer cylinders	Number of outer cylinders
	Number of outer cylinders with diameter
Shape	Basic shapes (Sphere, Cylinder, Cuboid, Cone)
Distances and angles	Frequency of distance, Frequency of angle

In the Topology search dialog box the following actions are possible:

New condition Add

Click on the New condition button.

-> The context menu opens. Select the desired Feature. Select the mathematical operator such as "equals" or "unequals" for example. Enter the value (textual or numerical).
Remove condition:

Select the desired row and click on .
Remove all conditions:

Click on the Remove all conditions button.

Commit

Takes over all changes and closes the dialog box.

Start the Topology search via Start search.

Commit and Search

Closes the dialog box starts the Topology search.

Cancel

Closes the dialog box without saving any changes.

Example 1 - Combination of Full-text search and Topology search

Enter "Hexagon bolt" as search term.
Enter <=30 as Largest dimension.

Example 2 - Combination of Topology search and Color search: See Section 3.1.1.6.4.6, “ Color search ”.

3.1.1.6.4.8.1. Topology search: Simple search with "Any parameter"

In the input field Any parameter there is no specification of variables. The entered values just have to match any parameters (e.g. diameter, length, etc.). So only a few numerical values of the desired part have to be known to find it. (Often variable names are not known and especially not consistently used in various parts.)

You can use boolean operators.

Rules:

Conditions are separated by empty spaces.
Ranges are given in the form 'x-y'.
At the other operators the numerical value is preceded by '=' (equal), '!=' (unequal), '<=' (less or equal), '>=' (greater or equal), '<' (smaller), '>' (greater). The '=' operator can be omitted, which means a solitary numerical value is an '=' search.

Some examples:

```
20 30 40
```
```
7 29 >100
```
Meaning: Find a part which contains the numerical values 7 and 29 and a value greater than 100.
```
3 >7 >=2
```
```
!=7
```
```
1e-2-3e-2
```
This is according to 0.01-0.03. After 'e' an exponent follows. In other words: 1 times 10 to the power of -2 until 3 times 10 to the power of -2
```
2.71-2.9 7.2-9.81 =3.4
```
```
4 >8 17-25
```

Example - Search with Any parameter

A Topology search via field Any parameter provides results if the searched value(s) is found in any parameter.

Call topology search and enter the desired parameters in the field Any parameter.
Click Commit.
Start the search.

In the search results, in the column Topology, you can recognize in each result line, on which parameter hits are traceable. The search values are colored.
