Zoom Using The Mouse Wheel

[Mk1_Oz]

I am sat here a frustrated man indeed!!!!!!!!!

 

I have draw up a 3D solid model of some framework and for a number of days have had the model line up beautifully (as it was originally drawn) such that a side view is exactly from the side.

 

Without me having a clue how, the model has now rotated itself slightly such that the same side view is actually slightly on a corner meaning I see more than just those side faces. I honestly do not know how this happened and I have not been able to get it back right using the various UCS commands. It should be noted that I have been changing the UCS regularly to date (without issue) to assist in my drawing.

 

Has anybody got any pointers as to what may have happened???? I have spent hours trying to recover from this to no avail.

 

 

Further, at the same time another annoying thing occurred. I normally zoom using my Microsoft wheel mouse with the focus of the zoom being where the mouse is. All of a sudden the same zoom using the mouse results in the zoom incrememnt per wheel click being higher but more importantly the zoom occurs from a set focus point regardless of where the mouse is at!!! This I am finding unuseable.

 

Yes I am new but I have tried and tried and tried. I have attached a screenshot and the file in case somebody wants to take a look PLEEEEASE

Make sure you haven't set to Perspective view.

You might post the file here so that someone can see what you have done.

Thanks JD. The file was attached in the OP underneath the screen shot. Will investigate perspective view (whatever that is)

JD. Used the PERSPECTIVE command and changed its variable to 0. Everything restored fine!!! Still baffles me how it got turned on........... THanks a massive amount.

It can be turned on with a right-click within the 3dview command (at least on older versions of AutoCAD, not sure about the current version).. the same method can turn it off.
