Dimensions have changed inconsistently?

rkettridge
Good afternoon.

I have been working on a drawing for a while now but the dimensions today have suddenly gone screwey. This is the original part of the drawing



But now i've been modifying the drawing (effectively cropping it down to a smaller section of the original drawing) the dimensions now look like this



All other posts i can find talk about the general scale setting which is set at 1. I could understand it if they were all the same, but some are 1/10th the length, some are 1/100th the length, others (not shown in this snippet) are correct.

I'm confused. Hope someone can shed some light

Thanks

CAD programs are accurate, when you cropped your entity, it's dimension changed too.

To solve your situtiation, you could edit dimension numbers, but that's not recommended,

Better to change the scale of drawing. For example select all, then from the left panel select modify (+) => Scale, set the right scale factor.

When i say i cropped, i literally just deleted the bottom half of the drawing. If i measure the lengths using distance point to point, the all measure fine so the drawing is right, it's just the dimensions that are wrong. As i said, i could understand if they were all wrong and in a consistent manor.

This post was updated on .
How did you crop? In LibreCad? Try deleting some dimension, and then do it again.

Selected the lines i no longer wanted and pressed delete.

Has this drawing initially been made with a different cad system, or edited with that and resaved?
Could be a matter of the settings in Options - Current Drawing Preferences - Dimensions. May we see that tab?
What are the units?
Aman's advice to redo a dimension is a good idea, what is the result?

**** found a solution(?) - see bottom of post ****

Drawing was drawn in Librecad and never taken outside of it. If i redo a dimension it still comes up as the wrong measurement.

I've just opened the original drawing that this file was cut down from and that also shows wrong dimensions, but if i open it in a dxf viewer (eDrawings in this case) it shows the dimensions fine. If i open this cut down drawing in the viewer it shows with the wrong dimensions (i'm assuming because i've saved it in librecad since they started showing wrong.

The dimensions options window looks like this...




Oh. Appear to have sorted it. If i change the 'linear precision' drop down to '0.0' (or anything else) rather than '0' they all come back??? Well that makes no sense!?

I can't reproduce the bug. I have drawn a line of 6200 mm length and dimensioned it with the same settings you had, with linear precision 0. It correctly read 6200. Maybe the file has been screwed up somehow, I have no explanation. Maybe you can repair it with saving with 0.0, reopen and set to and resave with 0 again?
Oh no, me stupid. I can reproduce it. You have set linear zeros to "remove right". Together with linear precision 0 this produces nonsense. So the user interface is not foolproof.

Another discovery: this bug seems to have been fixed in LibreCAD V 2.2.0 RC. It doesn't happen there.

Yes, indeed, this is a bug which is solved in latest code.
When precision was set to 0, all zeros on the right side were removed.

I just had the same problem. The zero's on the dimensions disappeared. Went into panic mode. I changed the precision to 0.0 as per the post above and the zeroes came back.

Glad I came here and was able to solve the problem so quickly. Tks.  

My version is 2.1.3, so I better update to get rid of this bug.
