I have small 1mm x 1mm round holes shapes that we cut, If I duplicate the design and reverse the image then resize slightly so the 1mm becomes 1.1mm.
In shape properties on the original I can change the 1.1mm back to 1mm and its all good. On the copy pasted and then reversed version, shape properties shows it as 1mm x 1mm but the width and height shows 1.1mm and 1mm so I cannot change all of the shapes back to 1mm x 1mm with the shape properties.
What do you mean by “reverse the image”?
Hi @RalphU what I mean is the Mirror function. so I mirror the drawing.
I was just busy again with a design and noticed again, I made the item smaller in the Height, then I selected all the o’s and shape properties I make it 1mm x 1mm but the normal width and height is not 1 x 1 mm.
Have a look at this Image visually you can see wit the eye that they are not 1 x 1mm
Check this also, if I manually change it back to 1mm x 1mm then the shape properties are out of wack also.
… for troubleshooting,
I’ve tried this on my Mac with the last LB version and can’t reproduce this error.
It really very weird, it happens with some file. others it doesn’t.
Have a look at this file, I manually made each of the small holes to 1x1mm but when I go to shape properties they are not 1x1mm

I see the same in this file I think it’s a little job for @lightburn people.
I am only speculating, but I wonder if it happens because the size is relatively small. It could be a tolerance issue within LB. If you look at the LBRN2 file with a text editor, there are some strings that need to be revised.
I can fix your test.lbrn2 file by replacing all occurrences of:
Rx=“0.51700002” Ry=“0.60699999”>
with:
Rx=“0.5” Ry=“0.5”>
and replace all occurrences of:
-4.3711388e-08 0.96675402 -0.82352942 -3.4800838e-08
with:
1 0 0 1
I agree with @bernd.dk - not sure how it happens, but @LightBurn should probably look into it.

The “XForm” is the problem. In LightBurn there are two things that can affect the size of a shape. One is the actual shape properties (Rx and Ry for a circle are the X and Y radius). The second is the “transform” of the object, which includes scale, shear, rotation, and position.
In your file, you have a transform applied that includes a scale factor. We don’t have a way to directly see or edit the transform in the UI, but most likely what happened is you grouped the circles, scaled or modified them in some way as a group, and then un-grouped.
When scaling a group, what LightBurn does is just apply the scale to the transform on the group object, which then affects the members of the group. When you un-group, the transform of the group is pushed into all the objects that used to belong to it, and that doesn’t push that change into the Rx/Ry values of the circles.
The “1 0 0 1” numbers that Ralph suggests means “no rotation, shear, or scale”. His suggestion is probably the easiest way to do this for the moment.
Thx for the update, yes I group everything reduce the size in the length or width depending on what is needed on the object. Then I normally need to keep the holes or circles at 1mm x 1mm so I ungroup select them all and then try to resize all at once.
For now what I do is I make one of them 1mm x 1mm at the length and width, then I copy the sizes it shows at shape properties, I select all and use the odd sizes found from shape properties and all are back to 1mm x 1mm.
As far as the laser see’s they are cut at 1mm x 1mm so I’m happy and laser is happy, it was just a bit of a struggle at first as I could not understand what is happening.
Hopefully someone else can see this and also find some benefit.
Just one thing, so if you say it is applied to the group, do you suggest I select the group Ungroup it, scale it down to the size I want, then change circles back to 1mm x 1mm while everything is still ungrouped.
Ok so I tested what you said and it definitely is the Issue.
I made everything a group scaled it down, then ungroup and check the circles would still show 1mm x 1mm in shape properties even though at the width and length it was smaller as well as visually smaller.
When I did the scale down while its not in a group I could normally manipulate the shape properties back to 1mm x 1mm and all was fine.
