I am using 2017 at a clients office, I normally use 2013 at home. The hide all types icon was missing from the heads up toolbar which I have now fixed, but when i select to show sketches they remain invisible. If I click on the sketch in the feature tree I can see it, but when I try to use the sketch as a reference for a linear pattern there is no way I can show it.
I have set the sketch to show in the feature tree but still no luck. Does this work differently now? Never had an issue with this ever but I cant get any sketches to show up no matter whether they are shown or not.
