Hi,

I have a polygon that I have to deform ( I attach an image ). I need to scale it vertically in order to fit a precise measure ( the measure is the vertical segment ).
I'm using the scale tool but I really can't understand how it works. It seems it works casually. I know I'm made the mistake but it's not really easy to understand.
What should I do in order to scale the object? In this case I have to deform it with differential scaling. but I can't use properly also the normal scaling.

Thanks, I'm going crazy for nothing


Have a nice day

A Smart Polygon can't be scaled with Differential-Scale. Create some layers and select the Layer which is for the polygon as working layer and change object type to lines. Select Object and use Edit> Change Object Type> Lines> Ok. Put other helplines in on other layer and select the polygon with select mask and disable select mask if selected. I made a Video. Watch the Hints.

It is easy. You cancreate the polygon as lines and not as "smart polygon" and you should always using layers for work. Otherwise you can use groups, but this is not so good. You can also selecting this six lines manually. Important is just that a "smart polygon" cant be scaled with differential scale.

What if I simple need to scale in one direction? Can I make it using the gripper? I don't need precision I can do it "by hand".
At the moment if I click on the yellow cube on the gripper it scales uniformally.

Ok perfect thanks. Done it. In this way I can scale in someway but not precisely.
It will be useful to have a function where you can "scale until a certain point": in that way you can easily equalize the dimension or follow a certain measure.
I don't know if I had explained myself, sorry for the poor english.

I made a post about wishing for a simpler easy and accurate method for scaling with the gripper about a year ago.

Just an idea for the gripper tool

And there is a beta in the pipeline :-)

As far as I know you can only use the scaleing technique tool on the gripper. Which with a bit of maths is okay but old style and more complicated.

I'm just wondering if others would find it useful to be able to put a plus or minus dimension into a sizing box?
So say I have a size some where in my drawing, say 369mm and I want it to be 400mm I select the whole lot, ( models and curves) pull the translate square on the gripper and type in (31mm divided by 2 = (15.5) or straight out 31mm, It depends on how you want to think about it or set up the interface.
The size of the whole of the selected items would rescale and the line would be 400mm.
For me it would be a big improvement to the gripper.


I know you can use the translate tool to do the same thing but its not ............ "The gripper".
