offset issue

[jbelle7435]

I am in sketch mode.

I create two lines(.25) up and then .25 over. I create a fillet of .250. Then I can not offset the fillet. It says

"can not offset beyond this point"

What is the reason behind this?

update: I can offset trimmed circles to my .250 radius/fillet but still not one i filet?

Are you offsetting inside the arc to a value larger than the arc's radius?

Hi  jbelle7435,

As a rule of thumb, if you wait to place your corner radius fillets as features and not in the sketch, you will find your Inventor models will work out better. Keeping your Inventor sketches as simple as possible is generally the best practice.

I hope this helps.
Best of luck to you in all of your Inventor pursuits,

Edit: Doesn't look like the others actually tried your steps.

Not sure why you would do that, but try this.

1. Edit the radius dimension to .125.

Can you offset now?

Change it back to .25

Where are the lines?  They are still there, right? (see step 1)  But zero length.

How would zero length entities be offset? 

Q. What is the expected behavior?

Now try this:

Start the Offset command but unselect Loop Select.

Select your arc and RMB Continue.

Now you are not selecting the zero length lines so it should work.

I will check on those soon and get back. Thanks

jbelle7435,

JD got it correct.

The issue is with a zero length line.

Have a Happy Halloween.
