Chained Move on X Stretch at Angle on Y

caddude — Wed, 29 Sep 2021 20:56:54 GMT

Hello community,

Is it possible to have a X-axis move action with a chained stretch action on a separate object that is stretching along the y axis? Don't worry, I have examples of what I'm trying to accomplish.

I have a person sitting in a chair, front and side view. As they stretch their feet out in the side view, I want their knees on a front view to move down, at an angle. I'm able to accomplish what I want with "puppet strings" but is it possible to do without? Please see CAD file attached.

You can turn the 'puppet strings' into construction lines which are invisible. Is that what you are after?

@Libbya thank you for responding. The puppet string one was an example of what I'm trying to accomplish. What I'm really after is the one below the puppet string example. I know I can put the "strings" on a noPlot layer, or a construction line, or just make them invisible. What I'm wondering is how can I do that movement, without having added lines. Can it be done, by using the chained parameters? When I try it now, the move action on Distance1 moves the distance2 in the x direction, which is not correct. I want Distance1 to move in X and Distance2 to stretch in the y direction. Do you think it is possible, or am I just dreaming of things that AutoCAD can't do? 😕

@Libbya aHa! I think I found it. I was able to make a collinear constraint from one knee joint to the other.
