Model Builder Tools Not Responding After ArcGIS Pro 3.5.2 Update - Unable to modify the parameters of geoprocessing tools

MairaMatias — Tue, 05 Aug 2025 20:55:09 GMT

Recently, I updated ArcGIS Pro to version 3.5.2 and am now experiencing issues with using Model Builder.

Specifically, I’m unable to modify the parameters of geoprocessing tools within Model Builder for models that were created prior to the update. The parameter windows for tools such as Clip, Calculate Geometry, among others, do not appear.

I created a new project and a new model for testing, and in this case, the parameter windows are showing up correctly for editing. When I copy the old model into the new project, I’m able to edit the parameters. However, if I simply create a new model within a project that was originally created in an earlier version of ArcGIS Pro and copy the model contents, I’m again unable to edit the parameters.

I’d like to know if there is a way to enable parameter editing for models created in previous versions, so that it’s not necessary to create entirely new projects and models.

I am having the same problem. I just updated our ArcGIS Pro to the version 3.5.2 and the model builder tools I had created seem corrupt. If I try to open a tool it prompts me to look for a file instead of the normal menu.

Same here. Running Pro 3.5.2 and can't edit parameters of tools in existing Models, nor can I edit anything in brand new models.

Hi all, I just spent the Summer struggling with the same problem. First, the fix is simple.

Click on a tool and select open.
When it does not appear,
Click on Alt-Spacebar - x simultaneously. The tool will open on the screen, typically in full-screen mode.

Second, the reason why this happens - the tool parameter boxes in Modelbuilder do not dock like those in Map or layout. Instead, they float above the program. Thus, when you try to open a tool and do not see it, this is because the tool is opening off-screen and even behind the program. Using Alt-Space-x brings the tool to the front.
Hope that solves the problem.
