Values for “Zoomfactor” can be set between 3 and 100. This behavior is independent of the Single Page Mode setting. Figure 3 shows the drawing display if the “Zoomfactor” is set to 70, zoomed out from the initial display as shown in Figure 1, rotating 1 click of the scroll wheel. Continuous Mode: Sets the mouse wheel behavior in continuous mode. The drawing zoomed out by 1 click of the scroll wheel.īy setting the “Zoomfactor” to a higher value, this will have the effect of zooming in and out quicker, therefore taking less movement of the scroll wheel. Under the Scrolling Direction section, click on ‘’Down Motion Scrolls Down.’’ Select the inverted scrolling option from the dropdown. Figure 2 shows the drawing display if the “Zoomfactor” is set to 10. Scroll down to the ‘’Scroll and Zoom’’ section. From time to time I will roll the wheel and it will become a 'scrolling' function and won't return to the zooming function unless I get out of the file and get back in.

I like the middle wheel on my mouse to zoom when I roll it and pan when I push it. Setting the “Zoomfactor” to a lower value would result in a smaller zoom increment and will have the effect of slower zooms, therefore taking more movement of scroll wheel to “Zoom” in and out. I have a mouse problem that keeps happening. The drawing in Figure 1 is displayed using “Zoom Extents”, so the boundary is just visible. The scroll wheel zoom rate is controlled by the system variable “Zoomfactor” (all one word), the default value is set to 60. “How can I change the rate of zooming in and out when using the scroll wheel?”

This is another question that cropped up during a recent training course.

Mouse wheel zooms instead of scrolls
