advanced rendering for AutoCAD
Hmmm.... There's definitely a units problem going on here-- not sure how it's happening though.
Try this:
Load the original image (1234.nXtImage) or the one you've just produced into the image editor. Run the cursor over the image and look at the numbers on the status bar. One of the numbers is distance from the eye-- it should be measured in meters but your image shows values like 6000 instead of 6. Also note that the Value fields read 0 (this is the problem-- the values are too low for the file format to handle.) As you cursor over the spotlights you'll see the values say something like 0.015-- they should actually read about 12000.
Something is messed up with the AutoCAD units. I would try settings INSUNITS to 1 then back to 4 to see if it corrects the problem.
Changing the units back to 1 and then to 4 via insunits before Nxt is loaded produces no change but doing it again after loading nxt corrected the problem. Only I now have to reset all materials again. Could this be automatic in the furture in Nxt?
Thanks again.
It is automatic-- normally this isn't something you have to worry about. Something happened to this model that messed up the units. We don't see this very often which is why you're not having this problem with other models. I'm guessing it had something to do with legacy versions having an incorrect scale. The material scales should have clued you in immediately. For some reason a scale of 1 meter was being used by nXt instead of 1 mm. In the future, check the Values in the status bar. Very low values or very high values will be one indication that the scale is wrong.
