i need help objects not matching in model space

[Anonymous]

Hello,

 I have a very odd problem. I have a file that for some reason just some of the parts will not match in dimension. I will measure a specific set of lines and it will show 4". Then I will draw an object that is 4" long and try to snap the object to the first 4" object. There is a very noticeable difference in size of the two objects and if I try to measure the distance it tells me that the distance is 0". I will include photos to show you exactly what I mean. Oddly enough it is only parts of the drawing that does this. Two gussets in particular and the orthographic side view of the gussets. Any help on how to fix this issue would be great. I have no idea how this even happens. Also I have many drawings using the same template and have never had this problem.

It looks like the dimension precision is rounding your distances to the nearest inch.

Check your DIMRND and DIMDEC variables settings.

DIMRND determines whether the dimension performs any rounding.

DIMDEC controls the units of linear precision.

Attach the *.dwg file here instead of pretty pictures and end all doubt.

Ok, here is the file. I made green circles around the problem areas. As odd as it may seem only certin parts of the drawing have this issue. Thanks a lot for all the help. Hopefully I can get this figured out.

the only item of interest I found are your parts are of different sizes in the views.  see xlines in the dwg I added.

btw the frame in real life is a 3d object; why is your work 2d?

The dimension showing as 0" is 1/32" long, but your DIMDEC is set to 1/15".

To get AutoCAD to display this correctly, change the Precision in your Primary Units tab to 1/32", as shown in the attached graphic.

thank you so much that worked great! and as you can see im no pro with AUTOCAD that is why i did the drawing in 2d ortho.
