Burner Posted June 10, 2015 Share Posted June 10, 2015 I am working on a basic 2D interior stone flooring layout shop drawing for a home. It's a 2'-0" x 2'-0" pattern, and maintains this pattern throughout various hallways and rooms. I need to shift the pattern a few inches vertically and horizontally. In order to do this, I want to snap to an intersection within this layout, and move it to a starting point that has been specified by the architect. I have set the Z geometry to 0", and used the Flatten command (selecting all objects). Even after both of these tasks, I still cannot snap to an intersection of lines within this pattern! The Apparent Intersection snap works just fine, but I want to find a solution to this problem. Is there something I am missing? Or, perhaps there is a command active that is not allowing me to snap? PS - I apologize if this is a repost. I already checked various threads prior to this post, but obviously have had no success. Quote Link to comment Share on other sites More sharing options...
RobDraw Posted June 10, 2015 Share Posted June 10, 2015 Are you referring to a hatch pattern? You can enable snap for hatch patterns in options. I'm afraid that moving the hatch is not going to give you the result that you expect. If I'm right, you are going to have to move the origin of the hatch.

Burner Posted June 10, 2015 Author Share Posted June 10, 2015 It is not a hatch pattern. I actually have 1/4" joints within the pattern separating each piece. Quote Link to comment Share on other sites More sharing options...
RobDraw Posted June 10, 2015 Share Posted June 10, 2015 I'm going to need a file so I can stop guessing. Is the intersection in question a gap or do the lines actually intersect? Quote Link to comment Share on other sites More sharing options...
RobDraw Posted June 10, 2015 Share Posted June 10, 2015 (edited) You can post the file here using the "Go Advanced" button at the bottom right of the quick reply box. I would advise stripping out any company related content like the title block. Edited June 11, 2015 by RobDraw Quote Link to comment Share on other sites More sharing options...

RobDraw Posted June 11, 2015 Share Posted June 11, 2015 Increasing the precision of your units reveals that the lines are not at Z=0. Quote Link to comment Share on other sites More sharing options...
rkent Posted June 11, 2015 Share Posted June 11, 2015 You can use Apparent Intersection but as Rob has pointed out the lines are not at a Z=0 elevation. You probably want to fix that instead. Quote Link to comment Share on other sites More sharing options...
Burner Posted June 11, 2015 Author Share Posted June 11, 2015 I guess I am still not getting the process you used to see that Z is 1/128. I my properties menu, I still see 0". How do I increase my precision? Or, how do I fix this? I want to avoid the Apparent Intersection snap. Quote Link to comment Share on other sites More sharing options...

rkent Posted June 11, 2015 Share Posted June 11, 2015 Burner, I would change the units to decimal when checking on things like this since many times the error amount will not register with the smallest Architectural setting. You will want to change it back to Architectural when you are done checking and modifying objects. I have some key combinations to toggle that for me, UA and UD so it is quick and easy to do.

eldon Posted June 11, 2015 Share Posted June 11, 2015 A quick way to change precision, without going through the units dialogue, is to change the system variable LUPREC (Length Unit PRECision) Quote Link to comment Share on other sites More sharing options...
rkmcswain Posted June 11, 2015 Share Posted June 11, 2015 AutoCAD Help is atrocious, no denying that. (Just goes to show, there is no demand for it to improve... but that is another topic...) FWIW, Help does say that the valid values are 0 to 8 Anyway, that is how I figured this out and a lot of other things many years ago. Trial and error a lot of the time. The tooltips that appear when you hover over a control used to (but do not now days???) show you the name of the system variable that controlled that settings. I really wish they would restore this across the board. Quote Link to comment Share on other sites More sharing options...
eldon Posted June 11, 2015 Share Posted June 11, 2015 (edited) Ok, for those who would like the details here is a list of the effect of LUPREC on Archtectural units in inches:- Precision LUPREC 0'-0" 0 0'-1/2" 1 0'-1/4" 2 0'-1/8" 3 0'-1/16" 4 0'-1/32" 5 0'-1/64" 6 0'-1/128" 7 0'-1/258" 8 I always work in metric units, and even I figured it out. But as already pointed out, using decimal units will give more precision than Architectural units. Edited June 12, 2015 by eldon Quote Link to comment Share on other sites More sharing options...
Cad64 Posted June 11, 2015 Share Posted June 11, 2015 This thread has been cleaned and some posts have been removed. I believe the information that remains should be sufficient enough to consider this topic resolved, yes? Quote Link to comment Share on other sites More sharing options...
