+# Modeling: Using design parameters
+
+You can read and update parameters that are part of the design.
+The simple design in this example has two associated parameters.
+
++++
+
+## Perform required imports
+
+```{code-cell} ipython3
+import os
+import requests
+from ansys.geometry.core import launch_modeler
+from ansys.geometry.core.modeler import *
+from ansys.geometry.core.parameters import *
+```
+
+The file for this example is in the integration tests folder and can be downloaded.
+
++++
+
+## Download the example file
+
++++
+
+Download the file for this example from the integration tests folder in the PyAnsys Geometry repository.
+
+```{code-cell} ipython3
+import requests
+
+def download_file(url, filename):
+    """Download a file from a URL and save it to a local file."""
+    response = requests.get(url)
+    response.raise_for_status()  # Check if the request was successful
+    with open(filename, 'wb') as file:
+        file.write(response.content)
+
+# URL of the file to download
+url = "https://github.com/ansys/pyansys-geometry/blob/main/tests/integration/files/blockswithparameters.dsco"
+
+# Local path to save the file to
+file_name = "blockswithparameters.dsco"
+current_path = os.getcwd()
+file_path = os.path.join(current_path, file_name)
+# Download the file
+download_file(url, file_path)
+print("File is downloaded to " + file_path)
+```
+
+## Import a design with parameters
+
++++
+
+Import the model using the ``open_file()`` method of the modeler.
+
+```{code-cell} ipython3
+# Create a modeler object
+modeler = launch_modeler()
+design = modeler.open_file(file_path)
+design.plot()
+```
+
+## Read existing parameters of the design
+
+You can get all the parameters of the design as a list of parameters. Because this example has two parameters, you see two items in the list.
+
+```{code-cell} ipython3
+my_parameters = design.get_all_parameters()
+print(len(my_parameters))
+```
+
+A parameter object has a name, value, and unit.
+
+```{code-cell} ipython3
+print(my_parameters[0].name)
+print(my_parameters[0].dimension_value)
+print(my_parameters[0].dimension_type)
+
+print(my_parameters[1].name)
+print(my_parameters[1].dimension_value)
+print(my_parameters[1].dimension_type)
+```
+
+Parameter values are returned in the default unit for each dimension type. Since default length unit is meter and default area unit is meter square, the value is returned in metersquare.
+
++++
+
+## Edit a parameter value
+
+You can edit the parameter's name or value by simply setting these fields.
+Set the second parameter (p2 value to 350 mm).
+
+```{code-cell} ipython3
+parameter1 = my_parameters[1]
+parameter1.dimension_value = 0.000440
+response = design.set_parameter(parameter1)
+print(response)
+print(my_parameters[0].dimension_value)
+print(my_parameters[1].dimension_value)
+```
+
+After a successful parameter update, the design in the backend might have been updated. Therefore, you must refresh the design on the client.
+
+```{code-cell} ipython3
+design = modeler.read_existing_design()
+design.plot()
+```
+
+The ``set_parameter()`` method returns a ``Success`` status message if the parameter is updated or a "FAILURE" status message if the update fails. If the ``p2`` parameter depends on the ``p1`` parameter, updating the ``p1`` parameter might also change the ``p2`` parameter. In such cases, the method returns ``CONSTRAINED_PARAMETERS``, which indicates other parameters were also updated.
+
+```{code-cell} ipython3
+parameter1 = my_parameters[0]
+parameter1.dimension_value = 0.000250
+response = design.set_parameter(parameter1)
+print(response)
+```
+
+To get the updated list, query the parameters once again.
+
+```{code-cell} ipython3
+my_parameters = design.get_all_parameters()
+print(my_parameters[0].dimension_value)
+print(my_parameters[1].dimension_value)
+```
+
+## Close the modeler
+
+Close the modeler to free up resources and release the connection.
+
+```{code-cell} ipython3
+modeler.close()
+```
