OK, so I have isolated one cause of the cursor disappearing. I'm just not quite sure what to do about it, and I suspect many people will be caught by this problem.
I have seen this across MAC and Windows 10 platforms, on Autocad 2024 Mechanical and Autocad 2024 3D.
When using an absolute coordinate system, such as would be the case for working on dimensions of mm and referencing a location in Queensland Australia, all objects are a substantial distance from the origin (you know, like 7000000000mm).
When I try to zoom in too close the who system fails, cursor disappears, relative locations of solids and other shapes fall apart.
The solution for me is to move the geometry that I'm working on back to the origin, then when I'm finished I move it back to the correct global position. NB. Changing to metres sort of works but not completely.
Question is, are others seeing this? and can Autodesk fix this please?
I have attached a typical file. I invite anyone to look at the building columns in the model and watch your cursor disappear as you zoom in on the base of the building columns.
Nothing to do with operating system, video card, damaged file... It seems that the distance involved just exceeds Autocads capability?
Surely many people want to work this way?
