oldsoftboss Posted March 1, 2009 Posted March 1, 2009 Title says it all really. I have created a 3D mechanical drawing showing air conditioning duct work missing steel beams and ties etc and am trying to add dimensions from the floor to the underside of the duct (Or at least check to see whether I have placed the duct at the correct height). Horizontal and angled dimensions are no problem, but when I try to add a dimension to the vertical it just don't wanna work. Dave Quote
papagyi Posted March 2, 2009 Posted March 2, 2009 May be you need to change to "UCS" align XY plane to vertical! Quote
oldsoftboss Posted March 2, 2009 Author Posted March 2, 2009 Thanks papagyi, may need a little help with that. I posted this in the beginners forum, but it got moved to here. If I change the USC will the other dimensions hold, or will they go haywire. If you could talk me through changing UCS, that would be really greatly appreciated. Quote
papagyi Posted March 2, 2009 Posted March 2, 2009 Here is sample screen shot for you fri! I play with "UCS" & UCS origin! Quote
Hedgehog Posted March 2, 2009 Posted March 2, 2009 For a start switch your UCSICON on & to ORigin... that'll give you a better idea of what is going on. In the UCS command use 3 point & select a relevant corner of the item you wish to dimension as your origin & try selecting a point along the plane which you wish to dimension along as your x axis, picking a point at 90deg to that on the plane you wish the dimension to appear in for your y... have a play & see how you get on.

oldsoftboss Posted March 6, 2009 Author Posted March 6, 2009 Thank guys. I will give it a go. Edit... 3 point - cant find that option, but rotated the object around using rotate3d and seemed to work. This seems the long way to go about things. Dave Quote
Came Posted March 7, 2009 Posted March 7, 2009 something like this type UCS Specify origin of UCS or [Face/NAmed/OBject/Previous/View/World/X/Y/Z/ZAxis] : 3 Specify new origin point : Specify point on positive portion of X-axis : Specify point on positive-Y portion of the UCS XY plane : simple see ucs tutorial on this page it's one of the most important things am learning basic Quote
oldsoftboss Posted March 11, 2009 Author Posted March 11, 2009 simple see ucs tutorial on this page Simple.... well, once you've done it. As you can see from your example there is no mention of the option "3" As for the tutorial, it didn't really explain dimensioning verticals in much detail. But hey, thanks. I will give it a go.
