hi fellas. quick question: I am trying to morph a circle to a 6. is it possible in illustrator? it appears you cant blend a compound path with a hole to another without blocking the hole. any ideas?

step 1 - before the blend

step 2 - after the blend

thanks.

Roei,

You may:

1) Select the circle and Object>Path>Offset Path by almost the radius, then Ctrl/Cmd+8 to create a Compound Path, then set a Stroke Weight that is sufficient to close the hole at the centre; you may select the 6 (outlined) and add a Stroke with the same Weight (especially if you wish to have the exact same height, which is different from the screenshot shown), or just leave it as it is;

2) Object>Blend>Blend Options set the desired number of steps;

3) Object>Blend>Make;

4) Enjoy.

Similar to jacob's suggestion.

Fake it.

I made a very small copy of the circle (almost invisible) and made a compound path of the 2 circles.

hi Ton thank you. I have tried to make a hole inside the circle and though this would be enough to make the blend work but it didn't for me. here are the steps I took.

1. created a circle on top of the big circle

2. used shape builder to cut it in

3. now I got this

blend still gave me this:

Maybe too many steps?

The objects may cover each other.

thank you Jacob. so you mean the short answer to my question is No, but I can use another shape to correspond with the hole in the 6? can you please speficy in more detail on what you are doing, my knowledge in Ai is somewhat basic, my intention here is to use this as a sequence in After effects to demonstrate morphing through Illustrator instead of After effects

Roei,

My suggestion is to turn the filled circle into a Compound Path consisting of the original circle and a tiny one at the centre, by using Offset Path, then apply a Stroke with a (small) Stroke Weight sufficient to close the little hole at the centre.

In this context I forgot to mention that in 1) you can reduce the W and H of the original/outer circle by the Stroke Weight to retain the original appearance, and just leave the 6 as it is in any case.

This will result in a Blend where the hole in the middle of the circle gradually grows from nothing (visible) to the counter in the 6, while the upper part of the 6 gradually emerges as the circular shape is withdrawn at the upper right.
