Rotate and Schale objects

Hello team

I have two questions.

I would like to rotate several objects e.g. individual letters of a text individually. So that the name is written below each other. The text should not rotate as a whole but within the text each letter. Of course, this should also work with multiple selection of different objects.

Secondly, I would like to scale a multiple selection of objects evenly. For example: 10 selected circles should be changed from 20 cm diameter to 25. (Yes there is a function with width, but then they do not stay in proportion).

The third question
How can I make the percentage display ‘fixed’?
If I scale an object from 100% to 110%, it will say 100% again instead of 110% in the other direction. This is of no use to me.

Thanks in advance!

I’m not aware of a way to do this. Curious if others have a method.

If you click the lock symbol in Numeric Edits toolbar objects will scale proportionally.

No way to change this behavior currently. The numbers represent the change from current size, not change from a base size.

Is there something specific you’re trying to do where you would need this to behave differently?

Yes, but actually no.

Each circle has a diameter of 25 mm.
I would now like to increase all of them to 30mm. The circles should remain in their absolute place. If I now mark all of them I have the height of 25mm but the width of the whole area of the circles.
If I now mark all and want to scale then the total area will be larger. However, this is given to me and I would like to increase only the circles themselves.

For the other problems I already thought of that. Too bad.

Thanks a lot

Yes, I have seen that.
Let’s see if I can use this method for myself.

Thank you

Sorry, I forgot about that.

It is more for testing. If I scale something up and then I don’t know how much % I can’t work with it.
For example, if I change from 3mm to 4mm woodcut.

Thats not what i want. Because it would change the whole width of all circles.
But they should stay at the same position. Just Bigger.

Here have a look.
The original is in the middle.

If I mark all and then set from 25 to 30 mm, the circles are also pulled apart in width. Just like the row below.

If I click on all the circles individually and change the diameter, they all remain in the same place and are simply larger. As in the upper row.

I would like to have this behavior with all the circles I select. For example, if I create a hole board and change the diameter without moving the circles, I would have to select each one individually.

I hope it is understandable what I mean.

I didn’t realize that was a requirement for you. And as you have already discovered that’s not how the tool behaves.

@RalphU’s solution is probably the best available but is limited to circle, rectangles, and polygons. And they all need to be the same size for this to work properly.

But you would know the new dimension? Is there a reason why you need it to be represented as a percentage from original? Is there something the new dimension leaves out in how you’re envisioning this?

Ah yes! Thats what i need. Thank you!

Of course, I could also make it about the size itself.
In my opinion, the percentage scaling makes no sense at all.
If I scale something to 110% and the display then switches directly to 100% because that is the new 100% I can not simply scale back with 90%. Then I have completely different values.

If I scale over percentages it is much easier for me to adjust my objects. For example, if I want to cut something out and the template has the cut at 2.5mm and I need 3mm, I select everything and set it to 120%. But then I can’t go back. Unless I remember the size or via ctrl+z, but that is not always possible.

I would find it quite useful if that when you scale over percentages the real value is displayed in comparison to the initial value.
Maybe there is the possibility that if you scale over the size in mm the new value is assumed as 100% and as soon as you start to scale over percentages the actual value is displayed.

I hope you understand what I mean.

Personally, I think this is the best option.

But! This is my feeling, because I just always scale over percentages.
If it does not work then it does not work.

It’s that simple! Anyway, thanks for all the help here!

I only ever use the percentage scaling if I don’t care so much about the exact actual final dimension. I usually do care about the final dimension so I usually mostly use the Width/Height fields to change scale.

This is probably why I’m not so bothered by the scaling behavior. I can see the appeal of having an “initial” value set but it also seems silly that whatever size you first made an object is meant to always stay with that object for eternity. In a lot of ways I think it might be more confusing for every object to have an initial scale of 100% and have that number automatically change as slight adjustments are to be made. And then what would the expected behavior be if you scale multiple objects? It would end up just getting messy.

Also, I think when you typically scale an object with percentage you’re doing it in convenient numbers like 150% or 200%. If for some reason you were already at 127% and wanted to double it, you’d now have to specify 254% instead of just 200%. Either way, I see benefits and drawbacks to either approach.

Yes, I’m right there with you.

I’m just used to scaling by percentages. Maybe that’s also because I did a lot of work for model makers before. And there it is mostly: this model please 25% larger and so on.

But it is like it is. If you know how it behaves then everything is okay.

Thanks for the input anyway.

Scaling is a bit weird. To see why, do this:

  • Draw a square
  • Scale the X axis to 150%
  • Rotate the square 45 degrees

At this point, what scale value should be shown in the X & Y scale values?

Right, but that is scaling along the object axis, not the world axis, which is what LightBurn does.

World axis (first) vs Object axis (second):
