precision problems to measure distances

[crispo]

I have a problem in using the "righello" tool to measure very small distances. I explain: in the architectural drawings imposed the units so that 1 corresponds to 1 meter. If I have to measure distances that are less than a centimeter, then let's talk about millimeters, when I activate the command to measure I see that the ruler moves to shots with irregular intervals, as if the snap mode was activated, but without a regular grid. The problem arises when, for example, I go to select the second point to measure, sometimes the cursor is as if it stops at a point other than the one chosen. to be sure of the distance I have to pull a line from point to point and check in the property window how long it is.
precise that I have a software that uses an oem of autocad 2010 and that in fact is autocad with some restrictions. with the autocad demo 2008 I don't have this problem and I don't want any system variables or options that I don't know.

attach a file that gives you problems, even emptied leaving just some object to check

for example this: I created a long line 0,0025. I also put a quota that correctly shows the length of the line. If then I go to measure it with the ruler gives me value 0. for convenience, having to draw metal carpenters, use as a unit factor 1 = 1 mm while in the architectural ones, always for convenience I use factor 1 = 1 m, only that to get the carpentry pieces I need to know the correct measurements up to 0.001 and that is up to mm. I hope it was a little lighter.

but what precision did you set in drawing units? you have to put at least 0.0000

 

[crispo]

Yes, it is set just like that....

Hi.
Excuse me if I interfere.
in the file "proof measure.dwg" the luprec variable which specifies the number of digits after the comma, is set to 2.
setting it to 4 the dist command shows the correct value.

Unfortunately I have already made this modification, as already written, but I have not solved.... maybe a bug? !

Yes, it is set just like that....

as specified by pielle60 is not set so in the precision of the design units.
have you used the luprec variable as suggested by pielle60 or instead the united command ? test with the latter, while being the same thing maybe that oem version for some strange reason does not record the luprec command

.... maybe a bug? !

If you have done all the operations correctly, it might be, even if it seems strange.

 

[crispo]

I confirm the above.... the variable is set correctly and remains recorded whenever I change it. I thought it was some other approach I don't know, but at this point I don't think so. for now I am working with 1 unit = 1 mm and therefore does not pose the problem.
Thank you
