deRabes Posted February 6, 2012 Share Posted February 6, 2012 HiList I am trying to offset a sketch. It offsets fine in an outward direction i.e. it gets bigger. But I can't offset it smaller for some reason. The loop is closed and everything seems OK but..... Any help appreciated Quote Link to comment Share on other sites More sharing options...
Jack_O'neill Posted February 6, 2012 Share Posted February 6, 2012 Without seeing the loop you are trying to offset, I can only guess that there's some part of it that would be self intersecting. Can you post a screen shot or the actual file? that would help. Quote Link to comment Share on other sites More sharing options...

rkent Posted February 6, 2012 Share Posted February 6, 2012 You can erase the small radius and offset the two large arcs, draw the fillets back in. Quote Link to comment Share on other sites More sharing options...
deRabes Posted February 6, 2012 Author Share Posted February 6, 2012 Thanks rkent. That worked a treat. Quote Link to comment Share on other sites More sharing options...
JD Mather Posted February 6, 2012 Share Posted February 6, 2012 It offsets in either direction for me - as long as I don't try to go beyond where the fillet would be zero (or less). Quote Link to comment Share on other sites More sharing options...
deRabes Posted February 7, 2012 Author Share Posted February 7, 2012 That was my problem. I assumed wrongly that it would adjust automatically. Thanks Quote Link to comment Share on other sites More sharing options...
JD Mather Posted February 7, 2012 Share Posted February 7, 2012 What would that assumed adjustment look like? Can you manually sketch what you expected? Quote Link to comment Share on other sites More sharing options...
deRabes Posted February 7, 2012 Author Share Posted February 7, 2012 I just thought the offset would close on the fillet until it became a corner and would continue decreasing on that basis I suppose. Quote Link to comment Share on other sites More sharing options...
JD Mather Posted February 7, 2012 Share Posted February 7, 2012 The arc entity would have to be automatically erased by Inventor and the coincident constraints at the endpoints of the arcs transfered to the endpoints of the lines. Sounds like a wish-list item. http://usa.autodesk.com/adsk/servlet/index?siteID=123112&id=1109794 Quote Link to comment Share on other sites More sharing options...
