This has been bothering me for a while, and I wonder if anyone else feels the same...
When you publish to pdf, you set a zoom factor for the hyperlinks to zoom to. This zoom factor is a percentage of the size of the symbol that you are zooming to. This seems to be a totaly useless number, because sometimes the symbol is a plc module, that streches from the top of the page to the bottom, and the zoom is way out, then sometimes the symbol is a little bitty arrow line reference, and you end up zoomed in so close, you have no idea where you are. The hyperlinks in the pdf file end up feeling random, and do not work well. I think the zoom factor should be based on the page size, maybe limits or extents, so if you set the zoom factor to 25, you would get zoomed in so a quarter of the sheet (25%) is visible with the symbol's origin in the center of the display. Seems much more intuitive that way.
