It's true that both formats are saved in simple text format...what appears to be a list of vertex coordinates; but it's how those vertices are referenced that appears to be different. I think a translation from rof to obj would require at the very least some kind of batch Find and Replace script.

Um .. .that goes without saying. But constantly hitting cntrl+Z would tend to screw up everyone's day.

Oh sorry, I thought you were asking for advice.

Thanks to all. Yes I think that may be the issue Tig. Will do some trials when I can.

Your screenshot of the orginal tells me that the component axes is set at the bottom left corner, which is the default position. If you move the camera around and that corner stays attached to the origin then my guess is correct. As I demonstrated above you need to move the axes to the bottom ceter of your horse so that it spins on its midpoint.

When I say frustrated its just that everything goes so slow. I have always wondered what it is like to control a mars rover with control delay. I could not believe selecting a texture, and hitting the delete button does not work at all any more. I have to right click and "erase" and wait about 7 seconds for it to go. Moving a texture or even something small is almost impossible. So frustration was expected and experienced. Loading the model into the renderer (8.2 million faces)takes about 6 minutes so about 12 minutes from hitting the render button to getting the first frame render. Strangely though the renders only take about 5 minutes to cycle to a good standard. I followed as much of the advice I was kindly given from this forum, and the computer I use is of a high spec so I think this is about the limit of shetchup. So basically it is just a very big model. It did test my patients though.

Thanks guys.

I've seen a similar report. It emanates from the way it was installed initially. Try uninstalling, then freshly reinstalling v2015. This time do NOT double-click the icon for the installer's exe file - even if you have 'admin-powers' - instead you should select its icon > context-menu > 'Run as Admin...' That way it's installed proeprly. Another thing to do is after it's installed find the SketchUp.exe file in the Program Files, SketchUp folder and context-menu > Compatibility > 'Always run this program as an administrator' should always be ticked [you'll need 'admin-powers' to do that] PS: Please update your User Info to suit the version you end up using...
