Generic Links weirdness

[neilyj666]

Any one shed any light on this issue?

I'm building a corridor for a small temporary river diversion from generic links that should be 3m either side with an additional 1m (for erosion protection) to the LHS as shown in the lower image.

I created the assembly but the corridor wasn't building correctly until I altered the 1m link to be 4m as shown in the upper image and the corridor built as expected (lower image) i.e. 4m to the LHS rather than the 7m that the assembly suggests

I'm totally baffled with this and have never had this issue with generic links which I typically use in preference to the prebuilt assemblies. I'm up against it time wise on this so can't take a closer look until next week but at least I have the corridor working as expected.

Thanks

I think whats going on is in layout mode the link offset is from the assmebly basepoint; so if you used one meter it thought it was daylighting fron one meter out.

That seems to be what was happening in the corridor initially - not very inuitive as the help refers to the attachment point rather than assembly basepoint - is this a bug or intended behaviour?

Thanks for that Steve - exactly what is happening; I still think it is very confusing and counter intuitive sonsidering I'm providing all the parameters and it can be built in layout mode so it looks correct, it just doesn't build the corridor correctly in this case.

I suppose my workaround is to just have a 4m offset (rather than 3m and 1m) which is how I've done it in the past and hence never had this issue before.

I think this has always been the case. The Links offset/width value is calcalated from the Baseline so your 4m offset should be 7m hence why the resultant section is drawn as a 1m off of the insertion point. Agreed it's counter intiative, I normally use an offset target to control this so have never really had the issue.

Have you tried to change the offset / width value to 7m so that it is drawn as 4m?

I thought a link's "offset" is measured from baseline, but "width" is measured from attachment point?
Regardless, I don't know why in layout mode "offset" links display as if the 'offset' is their actual width. Dumb behaviour.
