I was busy modelling when my complete model disappeared into the distance. I can see some sizes as the sizes becomes bigger when you zoom out. Eventually after Rolling the mouse wheel “maybe 3oo times” the sizes became bigger but there is a big cross in the centre of the sizes. The pixels are very bad. Please help me urgently, I have spent a lot of time on this project and its big!!
Attached is a picture of what I am seeing…
This usually means the view camera has moved very far from the model. It can happen if model content is far from the origin, especially in parallel projection. For starters, try switching to perspective and then doing zoom extents. That will often reset the camera. If that fails, try selecting a box around the origin, inverting the selection, deleting, and then doing zoom extents. If those don’t work, please share the model here (drag it into a reply window if it is not more than 16MB else post to a file sharing site and provide a link here). We can usually repair a model and tell you what was errant.
