|
Two diagonal braces and one horizontal brace bolted to a tower leg. |
Before you start
Create the following parts:
-
Tower leg
-
One diagonal brace to the outside of the tower leg
-
One diagonal brace to the inside of the tower leg
-
One horizontal brace (optional)
Selection order
-
Select the tower leg.
-
Select the diagonal brace on the inside of the tower leg.
-
Select the diagonal brace on the outside of the tower leg.
-
Select the horizontal brace (optional).
-
Click the middle mouse button to create the component.
Picture tab
Use the Picture tab to define the edge distances, and the dimensions that define the cut in the diagonal brace on the inside of the tower leg and the horizontal brace.
Dimensions
| Description | |
|---|---|
|
1 |
Horizontal cut dimension |
|
2 |
Vertical cut dimension |
Parameters tab
Use the Parameters tab to define the edge distances that define the location of bolt groups.
Bolt group locations and edge distances
Create your own defaults
You can define the default values of all the properties on the Parameters tab, except for bolt clearance and edge distance values of the diagonal braces, using text files named as tower_joint_clearance_N.txt, where N is the bolt diameter. For example, the files could be named as tower_joint_clearance_16.txt, tower_joint_clearance_24.txt, and so on.
The file can be located in the current model folder or system folder. If the text file for a particular bolt diameter is not found, the connection will calculate its own default values.
In the text file,
-
<L profile> = L profile name, for example, L200*200*20, L200/15
-
<C> = Distance from the edge of the part to the nearest bolt
-
<D1> = Distance from the heel of the part
-
<D2> = Distance from the outside edge of the part
-
<D3> = Distance from the heel of the part, away from the part
-
<D4> = Distance from the cut end of the part, if any
-
<E> = Distance between bolts
-
<H> = see the explanations for format 3 and 4
-
<B> = see the explanations for format 3 and 4
The format of the text file is as follows:
-
Format 1: <L profile>
<C> <D1> <D2> <D3> <D4> <E> | <C> <D1> <D2> <D3> <D4> <E>In format 1, the first set of values is for the first flange (h) of the part, and the second set for the second flange (b).
-
Format 2: <L profile>
<C> <D1> <D2> <D3> <D4> <E>In format 2, H and B have the same values.
-
Format 3: <L-profile>
<H> | <B>In format 3, the first set of <C> <D1> ... <D4> <E> values are assigned the value of <H>, and the second assigned the value of <B>.
-
Format 4: <L profile>
<H>In format 4, both sets of values are assigned the value of <H>.
Note that
-
Lines starting with a ';' or ' ' are skipped.
-
The L profile must start on the first position of the line.
-
There must be at least one blank space between the L profile and the first value.
-
The component only finds the first occurrence of the specified L profile.

Bolts tab
Use the Bolts tab to define the bolt properties, dimensions that define the location of bolts, and bolt pattern of bolt groups.
Dimensions
| Description | |
|---|---|
|
1 |
Distance between the bolts |
|
2 |
Select whether the defined bolt spacing is a minimum or an exact value. |
|
3 |
Bolt edge distance |
Bolt basic properties
|
Option |
Description |
Default |
|---|---|---|
|
Bolt size |
Bolt diameter. |
Available sizes are defined in the bolt assembly catalog. |
|
Bolt standard |
Bolt standard to be used inside the component. |
Available standards are defined in the bolt assembly catalog. |
|
Tolerance |
Gap between the bolt and the hole. |
|
|
Thread in mat |
Defines whether the thread may be within the bolted parts when bolts are used with a shaft. This has no effect when full-threaded bolts are used. |
Yes |
|
Site/Workshop |
Location where the bolts should be attached. |

Slotted holes
You can define slotted, oversized, or tapped holes.
|
Option |
Description |
Default |
|---|---|---|
|
1 |
Vertical dimension of slotted hole. |
0, which results in a round hole. |
|
2 |
Horizontal dimension of slotted hole, or allowance for oversized holes. |
0, which results in a round hole. |
|
Hole type |
Slotted creates slotted holes. Oversized creates oversized holes. No hole does not create holes. Tapped creates tapped holes. |
|
|
Rotate Slots |
When the hole type is Slotted, this option rotates the slotted holes. |
|
|
Slots in |
Part(s) in which slotted holes are created. The options depend on the component in question. |
Bolt assembly
The selected check boxes define which component objects (bolt, washers, and nuts) are used in the bolt assembly.
If you want to create a hole only, clear all the check boxes.
To modify the bolt assembly in an existing component, select the Effect in modify check box and click Modify.
Bolt length increase
Define how much the bolt length is increased. Use this option when, for example, painting requires the bolt length to be increased.
Number of bolts
| Option | Description |
|---|---|
|
|
Select the number of bolts created. |
Plates tab
Use the Plates tab to define whether shim plates are created between the braces.
