content: I am making an instructional document that will contain screen shots of sub-circuits from a schematic in Altium. The initial zoom level of a schematic in Altium is seemingly random, so it's difficult to get the same zoom over time such that the background "graphpaper" is the same size.Searching around does not find any methods to reset or fix the zoom level. All I can do is zoom in and out.A non-optimal solution is to screen capture the background and adjust from there. However, zoom+ and zoom- seem to work in increments of 3, so it's possible to skip over a value that was otherwise somehow previously achieved.Does anyone have a technique to set a specific zoom or pixels per inch?

content: Could you use a template (perhaps a sheet outline and title box) and then just hit 'fit' to have it zoomed to whatever the window size is? Of course, that would require the window to be a certain size, but that might be easier to arrange than a specific PPI zoom

content: Not sure how to solve the specific problem, but perhaps turning off the grid entirely, or exporting the whole schematic to an image or PDF and then cropping as needed in a graphics package would be an acceptable alternative?

content: CTRL + PagedownOr setup a pagesize that equals to your intended image size, and print to pdf from that.

content: I think I agree with dunkemhigh - type "vd" to fit the document to the page, then scroll in a discrete number of "clicks" on your scroll wheel. Should get you consistency.

content: Just tried it and they do indeed!Now if only graphics from outside imported (and scaled) in the PCB editor the same way, pain in the arse it is to get a PNG or something of the sort onto a layer at a size that works for you.Please tell me there is a way that I am just missing completely.Regards, Dan.

content: QuoteDon't think you can do vector graphics (except, perhaps, by dicking around with fonts) but for scaled graphics I usually have a high-res PNG which I paste as a union and then reduce to the required size. The current version of Designer has an explicit graphics paste function, but it's slower than the older workaround, even including the pasting into and out of Word to make the stuff compatible.
