Scroll zoom

[jheinze]

I have a drawing which I opened in AutoCAD 2007. When I use the scroll to zoom as I zoom the drawing moves toward the location of the mouse location.

I started a new drawing and when I zoom with the scroll wheel the drawing dosn't move toward the mouse location but seems to zoom to the center of the view.

What is "set" differently?

I'm just having a stab in the dark here. The scroll wheel is a mouse driver problem, within windows. You could also try to set MBUTTONPAN to 1.

[jheinze]

I have the same mouse. Both drawings open in the same instance of AutoCAD. Can't be a mouse driver. It must be some setting in the drawings that is different. MBUTTONPAN is the same on both drawings.

sorry , didn't read your last statement.

I'm out of ideas on this one

[Alan Cullen]

The only thing I could suggest is to go to acad help and try to find a variable for zoom. It may be a variable setting.

Can you try the variable 'ZOOMFACTOR' ?

[Cad64]

Zoomfactor is a system variable, so it cannot be different from one drawing to another.

jheinze, can you post the two drawings?

[Alan Cullen]

Now that's a good idea, Cad64. :D

[jheinze]

where can I post them?

[Alan Cullen]

How big are they?

111K at most

Here they are. The 66 block works as expected: zooms and pans toward cross hairs. The emergency transfer only zooms.

I had to purge the file it was to big. Here it is.

[Cad64]

Hmmmmm . . . . . no problem here. Both files work fine for me.

[Alan Cullen]

Yeah, the 110_EMER_TRAN_T.dwg doesn't seem to zoom quite as expected using the zoom wheel. But you can pan the drawing to a point you want and then scroll zoom.

Funny! I noticed the problem at first. Then in the second drawings (110_EMER_TRAN_T.dwg) I switched to 2Dwireframe visual style and zoom and Pan works perfectly. Switched again to others visual styles and the problem is disapeared.
Autocad.... sometimes it let me speechless

Works fine in 2d Wireframe.
