CUSTOM COMPONENT EDITING 12 End plate connection

2. Explode the connection

3. Define a custom component connection

Parameters to be used In this example we will input the following parameters:

Once all parameters have been defined the finished result sbelow:

Additional information: Plate Length Plate width Plate thickness Plate Material Bolt Size Bolt Grade

1 = Clearance From Flange Face 2 = Notch Depth 3 = Distance to 1st Bolt 4 = Bolt Pitch 5 = Bolt C/Ctrs

hould look something like in


The connection should also have the intelligence to adjust to suit a change in the profile of either the main or secondary beam.

2.2 Top notch

We are going to define the notch first. The values we would like to input are:

The clearance from the flange and the depth from the secondary beam top. We are going to use Magnetic user planes to control these variables

Open the custom component editor

Select the connection symbol, right click and select: Edit custom component.

Create User defined planes

1. From the Custom component editor toolbar select Create user-defined plane


2. Hide the main beam to make it easier to pick the plane

3. Pick three corner points of the cut to define the location of the plane and click middle button

Only the objects directly on the magnetic plane move with the plane.

Note that the objects must be inside the plane frames to move with the plane

Use the handles in the plane corners to enlarge the planes to cover all the polygon cut sizes possible needed.

4. Move the user plane handles one by one 200 mm to the directions shown.

The plane is now resized but not placed symmetrically according the cut


5. Move the plane to be symmetrically according the cut

6. Copy this plane to the underside of the notch

7. Repeat the procedure to create 2 vertical user planes on both sides of the notch


Make the planes

magnetic 1. Select all 4 planes and double click on one to open the properties dialog

3. Select the Magnetic check box, click OK

4. Create six user defined planes to the edges of the plates as shown to control the size of

stiffeners (Pick three points to define the location of the plane and click middle button)


You can also use user defined planes (Magnetic or not) to bind distances to

To make it easier to pick the stiffeners corners hide the main part

5. Create one magnetic to the middle of the plates plane to control the plate's position in depth


The objects must be inside the magnetic plane frames to move with the plane. To make this detail to work for significantly larger profiles we should enlarge the planes

3.3 Bind magnetic planes to the beam Tie magnetic

planes to beam 1. Tie the magnetic planes to the appropriate faces of the beam

Six new parameters appear to the Variables dialog box


2. Set the visibility of variables as false

The distance variable visibility in the variables list is by default False if the distance equals to zero. Otherwise it is True

3. Tie the magnetic plane in the middle of the stiffener to the connection plane shown

4. Name the variable as Position at depth and set it true

5. Close the editor and save the custom component

Test the custom detail

1. Change the beam profile from HEA300 to HEA200

The height and width of the stiffeners are now adjusted to the new beam profile whereas the thickness of the stiffeners is always the same.

2. Change the beam profile back to HEA300


3.4 Use equations to make the plate thickness intelligent

We will now adjust the stiffeners thickness to suit the web thickness of the beam so that it will be 1.5*beam web thickness rounded up to the next available plate thickness. The available plate thicknesses are 10, 12 and 16 mm.

We will first add a new variable that returns the beam web thickness multiplied by 1.5.

1.5 * Web thickness

1. Open the custom component editor

2. Add a new parameter and change its Value type to length

3. Add the equation =1.5* to the variable

4. Select the beam in the model

5. Right click the Primary part > Profile properties > Web thickness in the model browser and select Copy reference

6. Paste the reference to the Formula after 1.5*


A reference function refers to the property of object, such as the web thickness of a part. If the object property changes, so does the reference function value.

We will now use if-then-else statement to test whether the Variable P1 is bigger than the condition and set the value according to the result

Define the condition for the plate thickness 1. Add a new variable and change its value type to Number

2. Edit the Formula of the variable P2 to be =if (P1 < 12 && P1 > 10) then 12 else if (P1 > 12) then 16 else 10 endif endif

A custom part which has not been edited appears in its predefined size despite the points picked for creating it.

To adjust custom part length to the points picked you can bind the part end (by using handles or magnetic plane) to the corresponding component plane (as we


just did)

Number and spacing of rungs We created manually the bottom rung and multiplied it by using the array of objects macro. To parameterize the number and spacing of rungs we first define parameters for them and then tie these parameters to the array component in the model browser.

Number and spacing of rungs

1. Add a new variable (P2) to the variables dialog box and name it as Number of rungs and edit the Formula to be 13 (This will be the number of all the rungs)

2. Add another variable (P3) and tie it to variable P2 with the formula shown

Variable P3 returns now the number of rungs created by the array macro.

3. Add another variable (P4) and name it to Spacing of rungs

4. Edit the visibility of variablesD3 and D4 to hide


5. Edit the formulas of the variables D3 and D4 to be equal with P5

Ladder width We will now create two magnetic planes in the middle of the stringers to control the ladder width. We will adjust the magnetic planes to cover also longer stringers by binding the magnetic planes top handles to upper component plane (This way the magnetic plane is automatically resized according the picked positions for the custom part)

Since the handles of the rungs are positioned in the middle of the stringers they will move with the planes as well and adjust with the ladder width.

Create magnetic planes

1. Create a magnetic planes by picking 3 points in the middle of the stringer as shown and click middle button

2. Copy the magnetic plane to the other stringer

Adjust the magnetic planes for longer stringers

1. Bind one upper handle of both magnetic planes to the upper component plane

We can make our Custom components easier to use by customizing their dialog boxes. By modifying the input file of the custom component we can:

• Add pictures,

• Change the order and location of fields

• Add / rename tab pages.

We will next add a picture to the ladder simple custom part. We will then position the parameters and group them to two different tab pages: Picture and Parts

CUSTOM COMPONENT EDITING 50 Add user interface to ladders custom part

5.1 Create and save the picture We will first create the image and save it as a bitmap file. We will then add the image to the custom component dialog box by editing the custom component's input file.

To create the picture you can open an existing bmp from the teklastructures\”version”\nt\bitmaps directory or take a snapshot from an existing component dialog box and edit it by using any picture editing program. You can also create the bmp from the scratch

Remember to use the standard Tekla colors in the bitmaps

Create the bmp

1. Take a snapshot of the shown region of Ladder macro (S35) dialog box


2. Edit the picture to be as shown below using any picture editing program. (The size of the example picture is 62*250 pixels)

Place the bmp file to the system older Save the completed picture to the teklastructures\”version”\nt\bitmaps with a name

ladder.bmp

5.2 Add the bmp to the dialog box Tekla Structures uses input files to control dialog boxes

A custom component dialog box is controlled by an INP file automatically generated in the model directory. We will now edit the Ladder simple.inp file to customize the dialog box of our custom part

Edit the inp file

1. Open the Ladder simple.inp file in the model folder using a normal text editor (Notepad, WordPad...)

2. Add the text: picture ("ladder", 62, 250, 100, 50) to the inp file as shown below


3. Save the inp file (In txt format)

4. Close and restart the model to see the modified dialog box

5. Study the dialog box to understand the positioning of the picture

The number of fields and the coordinates added will effect to the size of the dialog box. Each tab page can contain 25 fields. If there are more than 25 visible fields, Tekla Structures creates another tab page


5.3 Position the picture and the parameters We can now plan the picture page and position the parameters P1-P6 according the ladder picture as shown. We will position parameters P7 and P8 at this stage at the bottom of the dialog box

Position the picture and the parameters

1. Remove the parameter names from parameters P1-P6

We have now defined parameters for all profiles. Next we will map these parameters into the custom component parts. 1. In the Custom component browser open the outer panel's Part > General properties

and right-click > Add equation over the Profile field. 2. Type the parameter's name into the field.

3. Repeat for insulation and the inner panel. Next separate the thickness and height into two individual parameters for each panel. 1. In the Variables dialog press the Add… button 6 times. 2. Write the labels as shown below:

3. Copy the corresponding values from the profile parameters into the "Formula" field

4. In the profile parameters write new formulas using the parameters:

5. Hide the profile parameters and leave the individual dimensions visible. 6. Set =P5 into the D9 and D10 formula fields to make the dimension react to thickness. 7. Set =P6 into the D7 and D8 formula fields to make the dimension react to thickness. 8. Close the editor and save the component.


In the model, double click the sandwich panel and modify the thickness and height values.


Appendix C: FAQ

Q1. Are there any reserved parameter names? A1.Yes for “bolt size” the parameter name needs to be “diameter”, & for “bolt standard” the name needs to be “screwdin”. Bolt size & bolt standard MUST have the same name. The names are automatically given when changing the “Value Type” so the bolt standard variable name will have to be changed to suit the bolt size variable name

If they do not have the same name the result will be as follows:

No value show in the “bolt size” dialog Q2. Is there any way to know what is bound to what? A2. Use inquire This will show all binding dimensions Q3. How to bind to a user defined plane?


A3. You can bind to user planes by simply selecting them. Note! They will not be highlighted. Q4. Are there any “best methods” to creating custom components? A4. Not really, although multiplication is faster than division. E.g. P1*0.5 is faster than P1/2. Also using magnetic planes is faster than binding all handles Q5. How to add pictures to “inp” file? A5. See the online help for detailed instructions Q6. If a picture is added to the inp file then changes are made in the editor is the inp file overwritten A6. Yes, you need to make a copy of the modified inp file Q7. When editing the “Inp” file I can’t use “Tab 4” A7. This tab is reserved for the General Tab Q8. I want to input 2 separate values for the plate width and thickness how can I use these values to make a “profile” name e.g. PLT200*10? And how to stop the values being input with decimal places A8. If as in the example below you use P2 for the plate width & P3 for the thickness use the formula “=”PLT”+int(P2)+”*”+int(P3)”. All text must be in inverted commas “”, int() will stop the values being input with extra decimal places.

Q9. Is it possible to change an existing binding? A9. No, you must delete it and re bind


Q10. Is it possible to rationalize a value to the nearest (for example) 10? A10. Yes, Use function round(), in this case round(P1, 10). Some other examples: round(17.5, 20) will round 17.5 to 20 and round(17.1, 5) will round 17.1 to 15. Q11. Can you use formulas in a distance list? A11. Yes, this is possible. Below is an example of using formula in distance list.

Distance list is treated as text in Tekla Structures, so formula should be written as e.g. P1 + " " + P2 or "2*"+P2. Q12. Is there any way of changing the variable name for parameters created by binding to a plane? (AB) A12. No, these are system defined names and will cause problems if the user is allowed to change the name (TIP: If you try to change the name it will allow you to change it but when you reopen the variable table is will have changed back) Q13. Is there a limit to the length of the variable label? A13. Yes 30 characters, but you can add more in the inp file Q14. What does the “create distance” command do on the “custom component editor toolbar?”


A14. With this command you select the plane first then the handle/chamfer to bind. It’s the opposite of “right click /bind to plane” Q15. What does “create distance for picked components handle points” command do on the “custom component editor toolbar?” A15. This is a command to automatically bind selected parts to their handles contact planes. (User planes 1st, then part planes of main & secondary member) Q16. Why isn’t the browser tree updated when I add or delete parts in the custom component editor A16. You need to refresh the tree by right clicking on the connection part of the browser

Q17. Can we change the standard properties of the custom component editor views? A17. You can change the properties but you cannot save them. Q18. Can we bind to the centre of profiles?


A18. Yes using boundary Planes, It may be necessary to rotate the view until you can select the center plane.

Boundary planes

Q19. Is there any difference between outline and boundary planes? A19. Yes “outline planes” follow the outline of the member and “boundary planes” form the outer shape of the member. TIP: Where possible it is better to use the boundary planes rather than outline planes as these are common between different shapes. Q20. Can we filter out the magnetic/user planes? A20. No not using filter or display but you can hide them using the new hide option, (user planes use the point section filter)
