Splitting Geometry

 From: karter 30 May 2008  (1 of 4)
 Hi group, I would like to be able to split a curve or surface edge without the need for making additional geometry......heres what I mean :- 1) Draw a horizontal line 100 units long or whatever you want 2) Run trim & select line 3) Add trim points 4) Input thru keyboard or [D] 20 units 5) Click and hold mouse to make c.line - x,tan (Notice MoI has x marked that position for you as End point) 6) Click on that point 7) Click done Nothing happens and the curve remains as it was ?? Somebody tell me what im doing wrong please :-)) TIA, --Paul

 1643.2 In reply to 1643.1 Hi Paul, you're not doing anything wrong, it is MoI that is getting confused in that situation. When you created the construction line on top of the original line, it basically is hiding the original line as far as object snapping is concerned. In order to add a Trim point, Trim depends on the object snap being attached to the object being trimmed - in this case the object snap is instead targeting the construction line and MoI is not seeing it as attached to the original curve. Even though it is on the right spot, Trim is not seeing it being on the correct object. I think I should be able to improve this for V2. In the meantime, you may have to create additional geometry for this case (construction line directly over top of a regular line inside of Edit/Add trim points) - if you place a point object there, you can trim and use the point object as the trimming object and that should work. - Michael

As usual your advice on creating a point using centrelines for trimming works well for the time being....cheers! Rgds, --Paul
