A little curious; just spent 30min trying to turn on/off automatic solve in a sketch of imported lines from a dwg file. The option seemed to be grayed out and not available; the turn on was requested by SW in order to dynamically solve a block drag in a layout sketch.
I went through multiple of possible combinations but option box did not come unstuck. (even tried old windows fix) Saved part, got out of SolidWorks, got back in, reopened part, opened sketch... same problem. Then tried a different tack opened new part setup sketch and option was available to switch on. Following this I got back into old part that I was having difficulty with and all seems to now work??
I may be missing something obvious here - but not sure. Any feedback here would be appreciated.
Recently installed SW2010 current SP and using Windows7 64Bit.
There have been issues with toggling Automatic Solve on and off after importing DWG or DXF files. I have found SPR 475505 that is similar to your situation. After some testing, the workaround in S-034166 seems to work.
- edit the sketch and box select all
- cut all the entities of the sketch
- exit the sketch
- create a new sketch on the same plane
- paste the entities there
You now will have access to the Automatic Solve settings in the new sketch.
