Hi there,

I would like to know if there is a way to keep the same ratio between 2 dimensions of multiple parts.

As you can see I start bij making a base construction sketch in dimension 1000x2000.

I start with drawing 'a' and dimension 'd'. the other lines of the square touch the base sketch (so it changes later if I adjust the size)

Then I sketch 'c' and dimension 'f', the rest touches the base sketch.

Then I draw 'b' and make collinear relations with  'a' and 'c'

So now if I changes the main dimension of the base sketch from 2000 to 1600 you get the next image.

But 'd' I gave a dimention earlier so this size does not change.

How can I keep the ratio between 'd' and 'e' so it look more the same?

It would be nice if you can say:       'd'  is always 1/4th of dimension e' for example

Any clever solutions would be appreciated.
