leader lines for angles in sketches

[laughingcreek]

When sketching a line, a dotted leader line is produce if I input a value for an angle.  This dotted line is not the same color as other diminsion lines in the sketch.  This leader line effects, and is effected by, the trim command.  If other lines cross it, thay are trimmed to it, and the leader line itself gets trimmed if selected.  (This is in DM mode, haven't tried in Parametric)

Hmm...  You are right.  I'll have to check to see whether we consider that the way it is supposed to work or if it is a bug.  Right now, it seems like a bug to me, I agree.

I'll look into it further.  Thanks for pointing this out.

The leader line is an auxiliary line to help user know the angle dimension is between the created line and the auxiliary line, it only shows up when user locks dim value for creating a line.

By default, it is an ordinary construction line, which is able to participate trim/extend and other operations. 

What's your expectation about the leader line ?

I can see how one could argue that this is intended functionality, but I think it would be improved if the "leader line" was just replaced with an extension line. This is what I have come to expect from CAD programs and it just makes sense to me. No need to add lines to the sketch that weren't drawn in. Additionally, if you remove the "leader line" you lose your angle constraint, which is not desirable.

Strangely enough, Fusion gets halfway there if you trim half of the "leader line."

"The leader line is an auxiliary line to help user know the angle dimension is between the created line and the auxiliary line, it only shows up when user locks dim value for creating a line."

I dont think this is necessary since the "auxiliary line" is always horizontal. I still think an extension line is better.

If you want this "auxiliary line" to not be horizontal you have to delete the horizontal constraint and adjust the line. You might as well just draw two lines from the origin of the first line and draw in an angle dimension. It would be faster and make way for the extension line method.

I agree with everything lukepighetti just said 100%.  I would never expect a leader line that is part of diminsioning to behave as anything other than a diminsion leader.  I was having all sorts of trimming issues because of this line, which was why I had brought it up to begin with.

Hi All,

I would shy away from referring to this reference line as a "leader line", or suggesting that it's a part of the dimension.  That reference line is created to dimension from, and isn't intended to adhere to any dimension presentation standard.

Imagine a slightly different workflow where you sketch a line without keying in an angular value.  In this case, no angular dimension is created, so no reference line is necessary.  If you then wanted to create that angular dimension after creating the line (using the Dimension command), you would need another line from which to dimension.  This is why Fusion must create a reference line when creating a dimension.  We've chosen to create it as a Construction line (orange, dashed) so that it doesn't affect your sketch profile (though it does participate in trim operations).

If you'd prefer not to have the reference line, you can delete the line (which will also delete the dimension), and re-dimension to another line in the sketch that you've created.

Hope this helps.

Thanks,

Charles

Hi Charles, please consider my previous message as a suggestion for future changes to Fusion.
