How to change radius of multiple circles in a sketch at once
How to change radius of multiple circles in a sketch at once
(OP)
Hi all,
Does someone know if there is a way to use like a reference as 'radius R of a circle' and setting the radius of 30 circles in a sketch to this parameter? It would be nice if I could change the radius of all the circles at once by changing this parameter R. For example by changing the R from 1.15 mm to 1.195 and immediately see that the circles all have this new radius.
I did a screenshot of the situation to clarify my question.
Kind regards,
Joachim

Use the Equal radius constraint....select all circles -> equal radius

Or maybe just create the one circle, then use Pattern feature ?

Yeah that's a good idea. But I don't know why it is not working. I removed all previous contrains of the circles and then tried to constrain them to equal radius. But when I click on equal radius I can't select any circle. And also if I first preselect them and click on circle it is not possible.
Kind regards,
Joachim

For example, in your last image, I see mainly a group of small semi-circles/arcs surrounded by a larger full circle. The full circles will all have equal radius constraints, then apply the same equal radius to all semi-circles/arcs. Now apply a dimensional constraint (dimension) for the full circles (radius or diameter). Make note of the expression value (pXX=1.5 if the radius/diameter of the larger circles is to be 1.5). If all the semi-circles are the same radius/diameter (let's say 0.5 and expression is pYY=0.5), you can drive them by making their expression value a formula by subtracting the difference between the larger circle and smaller circle (pYY=PXX-1.0). Then you only have to change a SINGLE dimensional constraint.
Hope this isn't confusing.

for example if:
p23 = 5.0 and
p145 = 5.0
to make them equal to each other, in the expression editor (tools -> expression) you can make
p145 = p23

The picture that the OP posted is showing a sketch which is made of 'Ellipses' and NOT 'Circles'. As I've shown below (and in the attached image file) the object on the Left is what an unconstrained 'Ellipse' looks like while the object on the Right is a 'Cricle':
The reason that you CANNOT select your 'circles' while attempting to constrain them to be equal radius, IS BECASUE THEY ARE NOT CIRCLES!!!!!
