Dynamic block question: how to align to the middle

Attached is an example / test block of a dynamic block.

I just need to know if this is possible so I can use it in my blocks for real use.

The block contains a rectangle that can be stretched. Also there is a circle that needs to keep it's size but must move along with the stretching of the rectangle.

This is not that difficult but how would I manage to keep the circle aligned to the middle of the rectangle.

See attached image of what I mean.

Thanks for the help!

you can either stretch the circle or move it. In either case use the same distance parameter but add a 50% multiplier to the circle action.

Huh..? I did not know it was possible, I will need to search for this!

Thanks Dbroada.

Dbroada,

OMG it is that easy indeed.

Thank you for the tip!

I can move on now.

Kind Regards,

and I've just prepared this to show you where to look

Thanks for your effort dbroada.

Good morning again,

(... if on the same side of the planet as I am ...)

~ My next question regarding dynamic blocks ~

Is it possible to stretch the rectangle (with a grip either on the left side or the right side) in a way that the rectancle itself actually stretches on both sides?

See image attached.

I mean, when created a lookup table with 2 variants: "500mm" "1100mm", the rectangle should expand to both sides. The circle should remain outlined _mid to the rectangle but should move along with the stretch (keep the same distance between the circle / rectangle.

Whatever I try, I still end up with the circle in the rectangle.

And that #%$@ .

Any help is much appreciated.

BTW most problems I have is when the circle is flipped to the other side. THen I can't keep it out of the rectangle.

I like you, another easy question (I think).

Again, a single distance parameter. I use one starting at the middle to the right hand edge (but find what works best for you) with only one grip. Now you need 2 strtch actions but both refering to the single distance. One strtch on the right hand side with a distance multiplier of 1,00and one stretch on the left hand side with a distance multiplier of -1,00 (OR an angle offset of 180)

edit

there again, had I read about the circle I might have not said it was easy. Does my advice help at all yet?

David, well of course it did help!

But this is my new challenge ...

If the circle is flipped, the stretching works reverse to the circle.

Hmm ... your method works but not with the circle...

is the circle flip part of the dynamic properties?

I think I would be inclined to have 2 circles with visibility parameters

I'll have a think about other possibilities but don't hold your breath waiting!

is the circle flip part of the dynamic properties?

Yes it is! As long as "unflipped" all is fine.

Once flipped it works reverse.

Thanks for your time / effort, I appreciate.

I can't think of a way to do what you want if you are flipping just the circle. I haven't tried but you may be able to flip the distance parameter & stretch actions.

Failing that it is back to the earlier suggestion of 2 circles and a visibility parameter.

I can't think of a way to do what you want if you are flipping just the circle. I haven't tried but you may be able to flip the distance parameter & stretch actions.

Then the stretch is working reverse.

Somehow I allway manage to think of things that cannot be done even in AutoCAD.

But WTH.... we'll work around it!

Thank you for helping me out, CU again!
