gargoyle27 Posted September 30, 2010 Share Posted September 30, 2010 i need to use a 3d dwg for use in a cnc program, the bottom line is when trying to draw anything, it automatically draws it on the xy regardless of what plane the lines i'm snapping to are on, i'm sure theres just a check box somewhere to change it so it draws on any plane or orientation, but i can't find it anyones help would be awesome Quote Link to comment Share on other sites More sharing options...
Cad64 Posted September 30, 2010 Share Posted September 30, 2010 Check the setting of your OSNAPZ variable. Controls whether object snaps are automatically projected onto a plane parallel to the XY plane of the current UCS at the current elevation. 0 Osnap uses the Z-value of the specified point 1 Osnap substitutes the Z-value of the specified point with the elevation (ELEV) set for the current UCS Quote Link to comment Share on other sites More sharing options...
gargoyle27 Posted September 30, 2010 Author Share Posted September 30, 2010 the value of osnapz is 1, is that what it should be? Quote Link to comment Share on other sites More sharing options...
Cad64 Posted September 30, 2010 Share Posted September 30, 2010 The answer to your question is in my previous post. You want it to use the Z-value of the specified point, right? So it needs to be set to 0. Quote Link to comment Share on other sites More sharing options...
gargoyle27 Posted September 30, 2010 Author Share Posted September 30, 2010 it's still not working Quote Link to comment Share on other sites More sharing options...
Oppie Posted September 30, 2010 Share Posted September 30, 2010 Can you post the dwg ? Quote Link to comment Share on other sites More sharing options...
gargoyle27 Posted September 30, 2010 Author Share Posted September 30, 2010 i use inventor for 3d stuff, and since the program needs dwg (or at least it doesn't accept ipts so we were trying a few different things to see what would work) i exported the ipt to a dwg, in the part there is a negative rotation of a circle thru a non perpendicular face and it ends up translating that as a spline instead of an arc (and the cam program didn't like that it seems), so i attempted to erase the spline and insert a 3 point arc, and it wasn't working because it would keep in trying to draw it on the xy plane this might be a silly situation and it might have an easier answer, but i am really unfamilar with 3d autocad as well as the limitations of this new program Quote Link to comment Share on other sites More sharing options...
Cad64 Posted September 30, 2010 Share Posted September 30, 2010 OSNAPZ didn't work? Ok, well, maybe you should just move your UCS to the elevation where you want to draw your lines then. Quote Link to comment Share on other sites More sharing options...
gargoyle27 Posted September 30, 2010 Author Share Posted September 30, 2010 what is UCS? and how do i move it? Quote Link to comment Share on other sites More sharing options...
Cad64 Posted September 30, 2010 Share Posted September 30, 2010 UCS = User Coordinate System What version of Autocad are you using? Quote Link to comment Share on other sites More sharing options...
gargoyle27 Posted September 30, 2010 Author Share Posted September 30, 2010 2009, i looked up ucs and i think i got it figured out, i was just totally baffled and frustrated that the cursor was snapping to a point, then the line or whatever i tried to draw, wouldn't snap to it when it was drawn Quote Link to comment Share on other sites More sharing options...
ReMark Posted September 30, 2010 Share Posted September 30, 2010 The UCS can be manipulated either via the command line or Dynamically. Quote Link to comment Share on other sites More sharing options...
JD Mather Posted September 30, 2010 Share Posted September 30, 2010 and since the program needs dwg... Uhmmm, why not simply save out as dwg from Inventor? Environment>AEC Exchange>Save as DWG Solid Quote Link to comment Share on other sites More sharing options...
