Parameters – Codeblocks

00:03

Setting and getting parameter values is a

00:06

cornerstone of the code block's workflow.

00:10

Here we use an if do block to get the value of the exterior panel material parameter

00:16

and evaluate if it is set to steel cladding,

00:21

the due portion of the block will set the value of the wall height parameter to 12.

00:27

If the material is found to be steel cladding

00:30

to ensure that the user cannot set the wall height to some other height.

00:35

When the cladding is in use,

00:37

we add a block to set the parameter to be read only.

00:42

Finally,

00:42

we duplicate the cladding text block and add it

00:45

to the block that sets the materials list values.

00:49

Testing the logic with the form shows that it works as expected

00:53

by setting the height parameter to be read only

00:57

and the value set to 12 but only when steel cladding is set as the material.

01:04

In the following example,

01:06

we use an if do else block to get the value of the

01:09

wall height parameter to evaluate if that value is less than eight.

01:16

The existing create list block is moved into the due portion of

01:20

the block and then duplicated and added to the L portion.

01:24

Two additional blocks are added to the list to include steel and aluminum cladding.

01:30

The logical intent of the code blocks is to offer the user

01:34

one list of values when the wall height is less than eight

01:38

and a list with more options. Otherwise

01:42

just as parameters can be set to be read only in the form,

01:46

they can also be set to be visible or not visible

01:50

here. An if do block is replaced with an if do else block,

01:54

then the interior material parameter is set to be

01:57

visible only when the exterior material is steel cladding.

02:04

Using the exterior material control in the form to test the logic

02:09

shows that it hides the interior material parameter as expected.

02:15

Another way to accomplish the same thing is

02:18

to set the visibility of the interior material parameter

02:22

to always be equal to the equation. Exterior panel material equals steel cladding

02:29

once again using the exterior material control in the form to test

02:34

the logic shows that it hides the interior material parameter as expected

02:41

in summary setting and getting parameter values is

02:45

one of the most common code block tasks

02:49

similar to parameter values. Lists of values can be set or get as well

02:57

setting parameters in the form to be visible or not visible as

03:01

well as read only or not read only is an option also.
