SAC - Offset a Link

[jmartt]

I may be just missing something obvious...

What I want to do is offset a link at a sampled slope.

I created AP1 at a delta X and Surface from P1. Whatever the resultant slope is, I want an offset line to have that slope.

I used the Define Variables to get the Slope.

But how do I offset the AL1 line, say, down 1 foot? (I don't want to go vertically down 1 foot from P1 and then draw another line at that slope, I want it offset.)

I'd settle for drawing a 1 foot auxiliary line perpendicular to AL1 and then creating the offset line from there, but (and this is where I think I'm missing something obvious), I can't figure it out in terms of slope.

What is the trick here? See screenshot and pkt.

Thanks.

You want to generate the next auxillary point using Angle and Distance. Make the from point and the reference point your P1 and AP1 with your offer distance. Then you can make your parallel link from there using the AL1.slope function to mimic the slope.
