Well, I have had a chance to play around with it for about 5-6 hours. Performance is only slightly better, I can't complete my last part as the performance is all over the place. Trimming sketches seems to hang nearly every time. Extruding parts as simple as squares is causing artifacts and extruding as if it is hollow at times.
To be sure it wasn't my sketch I deleted it and tried a second time and got the same results.
Either my iPad is junk, or my sketching is horribly wrong somewhere that I can't seem to see it or I have hit the limit with this workspace performance wise (same one I sent you).
In either case it has me frustrated so I need to step back from it for a couple hours or potentially the rest of the day. I haven't made any progress during this time frame. I have nothing to show as to why it happens it is completely random.
I will import the SHAPR file into a new workspace and delete all parts except the one I am working on, this should tell me if it is possible I hit the level the iPad can handle or maybe the app. I wouldn't think this would be the issue since all parts are hidden with the exception of the one I am working on, the screen doesn't have to render/draw them.
Its completely weird, odd and has me lost as to the cause.
