-andrew- Posted March 28, 2015 Share Posted March 28, 2015 I may have accidentally changed something...Trying to extrude a wall, I notice the measurement has changed to negative when trying to extrude upward in the Z plane: Not sure what to do here. thanks, Andrew Link to comment Share on other sites More sharing options...
rob Posted March 28, 2015 Share Posted March 28, 2015 Are you sure you are not looking up from the bottom? (Your axes are not showing in the pic.) Link to comment Share on other sites More sharing options...
-andrew- Posted March 28, 2015 Author Share Posted March 28, 2015 Yes - absolutely... All other dimensions were working properly. Link to comment Share on other sites More sharing options...
rob Posted March 28, 2015 Share Posted March 28, 2015 If absolutely means it is not upside down, perhaps you should post a file... Link to comment Share on other sites More sharing options...
DMclean Posted March 29, 2015 Share Posted March 29, 2015 Perhaps a flipped normal for the face you were trying to extrude? I know I,ve run into this occasionally before but unfortunately can't remember exactly what I did to fix it. I may have just wound up remaking the object and the problem went away. Was the original object directly generated or was it derived or booleaned from something else. I vaguely recall that I ran across it from trying to extrude from something derived, and if I recreated the face from scratch it was okay.

Des Posted March 30, 2015 Share Posted March 30, 2015 Doug is right. It has to do with the direction of the face normal before reshape. Try this, draw a 2d wall, show face normal in attributes, reverse the normal so it's facing down, use reshape to extrude. The measurement is minus in the up direction. But using the extrusion tool, it's correct no-matter what direction the normal is facing. It won't make a difference with the solid though, so it really doesn't matter unless you want to keep the wall as parametric for changing the height, in which case just stick a minus in.

-andrew- Posted March 30, 2015 Author Share Posted March 30, 2015 Hi all- I didn't intentionally change the normal, but maybe struck a key command or something... I'll take a look tonight! thanks, Andrew Link to comment Share on other sites More sharing options...
