svg export from on-line resources is at random scaling
From the app on my computer, I can choose how the units in the GeoGebra window will be represented in an svg export. That means I can get files at known scales out of GeoGebra. However, when I upload that applet as a GeoGebra resource, there is no dialog asking about scaling. Worse, the export doesn't make doesn't make a uniform decision about how to scale the drawing. It appears to scale the viewing window to about 10cm x 10cm regardless of the units in view. Because the viewing window is always a bit bigger than the object being exported, this means the actual drawings are even more randomly scaled than just the arbitrary window scaling. For instance, I'm trying to draw sets of gears to laser cut. They all have to be cut to the same scale obviously or they won't work together. Yes, I can afterwards measure the diameter of the central hole that is the same for all of them and then compute the rescaling value for each gear and then rescale them in Inkscape. But why do I have to do all this work? There is a numerical scale built into GeoGebra. Use it consistently.
