I have not been able to FORCE it or intentionally make it happen..... It just happened again.
I am using product version O.49.0.0 autocad 2018. I did turn off the hardware acceleration, after one of the reply's.
I have reviewed the recommended minimum specs , this is a corporate owned pc, It is and DELL and it meets and exceeds the minimum requirements.
I have noticed this issue mentioned on numerous message boards while searching for a fix or how to correct the issue after it happens, other than closing the file, not exiting AutoCAD , I tried the 4 options that were in the link sent on Thursday,
This generally happens when a viewport is active and the display is locked. The layout happens to be zoomed in or out and a mouse based Pan or a Mouse wheel zoom is done. And the crosshair decides to just go away. Only the arrow is usable while over a ribbon of tool bar.
To bring the crosshair back
Try any of the following:
* Click anywhere on the ribbon. This is the first thing I do and it has never worked for me, in the past..
* Move the mouse cursor over the Viewport Controls in the upper-left corner of the drawing window. Getting the cursor over this area when it is not visible is a challenge, even with using the control tap to flag where the cursor should be, challenge. But it actually worked this time.
* Change the visual style. In the past it has also happened while in the model tab and changing the visual style has not worked then.
* Switch between model and layout tabs This is an other I have tried in the past and today my Manages was looking over my shoulder as it happened so I dug out reply. This has not corrected it for me in the past, and did not today.
I have tried most of the other items
* Switch between model and layout tabs. This has not worked so far.
* Minimize and then restore AutoCAD. This I do not recall trying this
* Close and reopen the drawing. This is the 100% go to fix for me.
* Exit and relaunch AutoCAD. It has not gone this far unless it repeatedly happens in a single acad session.
* Change the color of the crosshairs. This has not worked for me
* Open a blank AutoCAD template, copy the model using COPYBASE from a point within the model and then paste the model to 0,0. This might be problematic if the original file has multiple layouts , having to transfer them to the NEW file and having to double check and adjust the viewport freezes, once they are transferred, or copy an pasted. Or there might be issues of having to reconnecting external references.

* Double-click the mouse wheel to zoom to extents.
