Edit a model does not open Model Builder

[Nicole_Ueberschär]

It happened now a several times that I created a model in Model Builder (ArcMap 10.5.1) and when I try later to edit it, the model builder is not opening. I tried to open the affected models from ArcMap and also from ArcCatalog but without success. It might be that I had minimized the model builder window when closing the mxd file but I also closed all other windows hoping to find the small window for the model builder somewhere. No chance.

Does anybody have an idea if there is a way to recover these models somehow? I wasted already so much time on redoing models that suddenly didn't open again. 😞

Edit: I was able to open the model in ArcGIS Pro, saved it under a new name, exported the toolbox from ArcGIS Pro to 10.5 and was then able to open the model in ArcGIS again, only that I had to fix some of the processes again. I would still be interested if there is an easier way...

Another approach to this issue of the little window hiding under the taskbar is to set your taskbar to hide when you are not using it -- and reclaim that valuable strip of screen real estate!

Perfect, thank you!

That worked for me.

Thank you!

That was the solution!  I have 11 student exercises with models to grade for this exercise, and I have spent about two hours trying to find the first model.  You saved me.

I just had this same problem with a model window not coming up in ArcMap and it wasn't hiding behind the taskbar. I found that opening the model in ArcPro resolved the issue as the model opens in the application instead of a separate window.

This happened to me also.  The only way I could recover the off-screen window was to plug in to an external monitor with more pixels.  Then I could see the Model Builder window way to the bottom-left of the original extent of the laptop monitor.
