ArcGIS Pro Release:<\/strong> 3.4<\/p>\n

Building custom tools<\/a><\/span> in ArcGIS Pro gives you the opportunity to automate repetitive workflows or design tools that are tailored to your analysis. You can use ModelBuilder or Python to create tools inside custom toolboxes<\/a><\/span>. And by designing and sharing your toolboxes, you enable others to benefit from your expertise with a customized tool to help them work more efficiently.<\/p>\n

This blog explores some tips and new features in the latest releases for building custom tools, including:<\/p>\n

\u2022\u00a0 <\/strong>Build custom tools<\/strong><\/a><\/span>\u2013Learn how to build a custom script<\/a><\/span> tool.<\/p>\n

\u2022\u00a0 Document custom tools<\/a><\/span><\/strong>\u2013Use the Tool Properties<\/strong> dialog box to document custom tools.<\/p>\n

\u2022\u00a0 Attributes<\/a><\/span><\/strong>\u2013Add an Enable Undo<\/strong> toggle and banner messages to custom tools.<\/p>\n

\u2022\u00a0 Environments<\/a><\/span><\/strong>\u2013Select a subset of environment settings<\/a><\/span> your custom tool supports.<\/p>\n

\u2022\u00a0 Parameter Controls<\/a><\/span><\/strong>\u2013Use the controlCLSID<\/code> property to set a custom tool parameter control.<\/p>\n

Note<\/strong>: Much of this new functionality is only available for custom tools stored in the new ArcGIS toolbox (.atbx) format introduced in Pro 2.9. So, if you\u2019re still using legacy toolboxes (.tbx), copy and paste your tools into a new toolbox for an enhanced experience.<\/p>\n"},{"acf_fc_layout":"content","content":"

Similar to a new toolbox you\u2019d buy at a hardware store, you should fill your Pro toolbox with useful tools, like custom script and model tools.

You can create this script tool in a toolbox by following these steps:<\/p>\n

1)\u00a0<\/strong> Right-click a toolbox, then select New<\/strong> > Script<\/strong>
\nThis opens the Tool Properties<\/strong> dialog box, where you can set the tool\u2019s general properties, parameters, execution and validation code, and environments.<\/p>\n

2)<\/strong> On the General<\/a><\/strong><\/span> tab, provide the tool with a Name<\/strong> and Label<\/strong>.<\/p>\n

3)<\/strong> All tools have parameters, which are the input and output values or conditions that define how a tool runs. On the Parameters<\/a><\/strong><\/span> tab, you can set the tool\u2019s parameter properties in a grid. This custom tool has three parameters:<\/p>\n\n\n\n\n\n\n
Label<\/strong><\/td>\nName<\/strong><\/td>\nData Type<\/strong><\/td>\nType<\/strong><\/td>\nDirection<\/strong><\/td>\nDependency<\/strong><\/td>\n<\/tr>\n
Input Feature<\/td>\nInput_Feature<\/td>\nTable View<\/td>\nRequired<\/td>\nInput<\/td>\n<\/td>\n<\/tr>\n
Expression<\/td>\nExpression<\/td>\nSQL Expression<\/td>\nOptional<\/td>\nInput<\/td>\nInput_Feature<\/td>\n<\/tr>\n
Updated Feature<\/td>\nUpdated_Feature<\/td>\nTable View<\/td>\nDerived<\/td>\nOutput<\/td>\nInput_Feature<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Note<\/strong>: The tool needs a derived<\/a><\/span> parameter with a dependency on the input parameter. This indicates the dataset specified as the input is updated by the tool\u2019s code, and it allows the tool\u2019s updated output to be chained to other tools in ModelBuilder.
\n<\/a>
\n4) If you were to try to run the tool at this point, it would not work. When someone clicks Run<\/strong> on the tool dialog box, the tool runs a script to process the parameter values. Open the Execution<\/span><\/strong><\/a> tab to see the script editor. Below is the tool\u2019s execution code:<\/p>\n"},{"acf_fc_layout":"sidebar","content":"

Use Tool Properties to Document Custom Tools<\/h1>\n

If you want to share your tools with other people, you should provide information, illustrations, and details about how the tool works. You can document custom tools<\/a><\/span> in the Tool Properties<\/strong> dialog box or the tool metadata<\/strong>.<\/p>\n

Customize Parameter Controls using the controlCLSID property<\/h1>\n

Parameters are like the control panel for your tools, where you set the inputs, outputs, fields, distances, or make other modifications to guide how users work with your tool.

Note<\/strong>: Parameter controls cannot be customized in model<\/a><\/span> tools. Model parameters typically come from the geoprocessing tools inside the model, and the control is inherited from the original tool.<\/p>\n

To modify a parameter control, you must set the controlCLSID<\/code> property in the tool\u2019s validation<\/a><\/span> code with a value that is compatible with the parameters Data Type<\/strong> property.<\/p>\n

Alternative controls are supported only by specific parameter data types. For example, say you have a tool with a parameter that uses a Double<\/code> or Long<\/code> data type with a defined minimum and maximum value (Range Filter).<\/p>\n"},{"acf_fc_layout":"image","image":{"ID":2609902,"id":2609902,"title":"param_control_01","filename":"param_control_01.png","filesize":17539,"url":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/12\/param_control_01.png","link":"https:\/\/www.esri.com\/arcgis-blog\/products\/arcgis-pro\/analytics\/build-custom-tools-in-arcgispro\/param_control_01","alt":"Set a filter on a numeric parameter","author":"314022","description":"","caption":"Set a filter on a numeric parameter.","name":"param_control_01","status":"inherit","uploaded_to":2608682,"date":"2024-12-03 21:26:38","modified":"2024-12-03 21:27:00","menu_order":0,"mime_type":"image\/png","type":"image","subtype":"png","icon":"https:\/\/www.esri.com\/arcgis-blog\/wp-includes\/images\/media\/default.png","width":872,"height":210,"sizes":{"thumbnail":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/12\/param_control_01-213x200.png","thumbnail-width":213,"thumbnail-height":200,"medium":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/12\/param_control_01.png","medium-width":464,"medium-height":112,"medium_large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/12\/param_control_01.png","medium_large-width":768,"medium_large-height":185,"large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/12\/param_control_01.png","large-width":872,"large-height":210,"1536x1536":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/12\/param_control_01.png","1536x1536-width":872,"1536x1536-height":210,"2048x2048":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/12\/param_control_01.png","2048x2048-width":872,"2048x2048-height":210,"card_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/12\/param_control_01-826x199.png","card_image-width":826,"card_image-height":199,"wide_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/12\/param_control_01.png","wide_image-width":872,"wide_image-height":210}},"image_position":"center","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"

Summary<\/h1>\n

In ArcGIS Pro, you can create custom tools using Python or ModelBuilder, and you can use the Tool Properties<\/strong> dialog box to configure your tool\u2019s properties. Over the past few releases, we\u2019ve added more options to make it easier to document and design your custom tools. You can use Tool Properties<\/strong> to document<\/a><\/span> your tools, set tool attributes<\/a><\/span>, tool environments<\/a><\/span>, and modify the parameter controls<\/a><\/span>.<\/p>\n

To see what else is new in ArcGIS Pro 3.4<\/strong>, please visit the What\u2019s New documentation<\/a><\/span> and post your questions in the ArcGIS Pro board<\/a><\/span> in the Esri
