2.2.2 The “Modify” button of the Tekla Structures “Grid properties”
The “Modify” button performs settings modifications in a model.
If no modifications are done, the “Modify” button does not
perform any action. Changing the grid settings in the model requires modification
of the values of the parameters and their confirmation by pressing the
“Modify” button.
The “Modify” button runs the updates only in case at least
one of the values of the parameters is changed. Let’s examine the
first parameter, by writing into the respective field a new value and confirming
it by pressing the “Modify” button.
The first “Grid Properties” menu field stands for
Coordinates,
which specifies
the distances between the grid lines.
Note that coordinate 0.000 in all the fields is a constant value and should
Make up the grid coordinates values for the axes X, Y, and Z equal to
Proceed as follows:
1. Make sure all operations are canceled or press the ESC key
2. Make sure the required grid is selected (enabled), if not, make a left-click
3. Press the “
Modify
” button.
4. In the ‘ Replace confirmation’ dialog window, confirm the
updates by clicking the “Yes” button (valid for the older TS
versions).
The selected grid gets shaped as follows:
Tekla Structures v21.1
Note that the “Modify” button acts only in case there was
selected at least one object. If no objects are selected, pressing
the “Modify” button performs no modifications in the 3D model.
Tekla Structures v2021
Note that prior to any parameter value modification, the “Modify”
button is not active. Introducing any modifications activates the button.
Thus we created the grid in the coordinate 0.0.0, defined by axes X, Y,
Z. The current alignment of the axes is displayed at the right
bottom
corner of the view.

Add a grid line at the axis OX at the distance of 6 meters from the origin
point. Go to the "Grid Properties" menu, and insert into the
X-axis field the required distance value of 6 meters expressed in mm right
after the coordinate 0.00. Spacing is the mandatory separator between
the field values.
Tekla Structures v21.1
Tekla Structures v2021
Let's create one more grid line on the axis X at a 1000 mm distance
from the previous line, thus inserting into the X-axis field the following
values: “0 6000 1000”. The TS automatically sets up the decimal
places after the comma. Keep in mind that all the dimensions shall be expressed
in millimeters, and the spacing between values is the mandatory separator.
Confirm the updates by pressing the “Modify” button and compare

Thus adding up a new grid line requires introducing into the axis field
a new distance value. As a case study, let’s insert two more grid
lines with the distances between them of 6000 mm.
Thus the “0.000 6000.000 1000.000 6000 6000” values
Note that the consecutively repeating values are automatically simplified
where:
N stands for the number of occurrences of a value
L stands for the distance value between the grid lines
Tekla Structures v21.1
Tekla Structures v2021
Let’s modify the X-axis coordinates values from “2*6000.000”
Tekla Structures v21.1
Tekla Structures v2021
Note that the newly created grid lines are not tagged by any symbol, since
Add to the Y-axis 4 new grid lines with the distance between them of 6000
Proceed similarly to the algorithm for completing the X-axis coordinates
field and refer to the
below
picture:

It is important to understand that the coordinate field values for the
axes X and Y represent distances between the grid lines, but in the case
of the Z-axis field, the values define the elevation point from +0,000.
Insert the following values into the Z-axis coordinate field: “0
3000”
Tekla Structures v21.1
Tekla Structures v2021
The elevation grid line was created, but it is labeled not as +3,000,
according to the coordinates field value, but -1,500 which is incorrect,
though the real distance to the grid line is +3,000 meters. It is
always a very confusing case for those who just started to work in the
TS.
That is why we would like to highlight that a label is just a text, editable
at the “Labels” section fields. The “Label” field
is a specific field, where the grid lines’ titles are specified.
We will get back to this topic, meanwhile, let’s familiarize ourselves
with all the features of the “Label” section.
Tekla Structures v21.1
Tekla Structures v2020
The grid lines titles may not have an orderly sequence and can be expressed
in letters of the alphabet, as well as by various symbols. Thus the
grid lines titles labeling is not automatically set up by TS and is due
to the manual typing in. The already existing labels are the default values
of TS and their number is limited.
Let’s write in the missing gridlines titles and adjust the elevation
Let’s write in the missing labels for the X-axis grid lines by inserting
their titles by space and pressing the "Modify" button.
Tekla Structures v21.1
Tekla Structures v2021
Thus all the X-axis labels are displayed on the view. If required,
proceed the same way for the Y-axis. In the current case study, it is not
required. All the Y-axis labels are tagged.
Tekla Structures v21.1
Tekla Structures v2021
Let's fix up the appropriate titles for the Z-axis grid lines.
To get a clear understanding that the values introduced into the “Labels''
field are just textual data, let’s express the grid line titles in
words: ”Alex”, “John”. Compare your results
to the below:
Tekla Structures v21.1
Tekla Structures v2021
As soon as the spacing is the mandatory separator, we can not employ this
symbol into the grid lines titles, unless we enclose the title body into
the double quotes. Exercise setting up the following titles for the Z-axis
grid lines: "Ground level", "1st floor". Compare your
results to those presented below:
Tekla Structures v21.1
Tekla Structures v2021
Along with the elevation values expressed in mm, the symbols "+/-"
shall be specified. Let’s write in a couple of elevation labels in
the ascending order.
Do not deviate from the ascending order:
”-250 0 3000 6000 9000 12000”,
this being a very strict TS requirement.
Example of the labels with the distances expressed in meters:
“-0.250 0.000 +3.000 +6.000 +9.000 +12.000”.
Do not miss the
0.000
elevation label!!
If there is a large number of labels to be inserted, follow the shortcut
by copying the Z-axis coordinates field values, pasting them to the labels
field, and editing the values’ line by adding the symbols ”+/-"
and converting the values from mm to meters.
Also, you can use a special plug-in to perform automatic labeling in a

This section defines the required grid lines extension from the intersection

If we specify the field values equal to zero, then the grid lines endpoints
coincide with the grid lines intersection points, which makes it quite
difficult to examine a drawing, due to the collisions between grid lines
and grid lines labels.
Examine the case by setting to zero all the “ Line extensions”
Tekla Structures v21.1
Tekla Structures v2021
Substitute in succession the values of the parameters to 5000 mm and examine
Each axis ( X, Y, Z) has its origin and the endpoint, thus the extensions
of the grid lines shall be applied to the beginning of the axis and its
end accordingly.

After completing the exercise, set out the values of the “Line
extensions” parameters to 2000, thus preventing the interference
of the grid lines extensions.
