Limiting a left and right movement of a point located on a horizontal sketched curve line.

[ProEDesigner00]

Hey all

I have recently learned about motion skeletons and how to use them.

I have a horizontal line representing a left and right path of a point. I want to be able to limit the distance that point can be moved when highlighting it and dragging it left and right. This point is a line segment end that in the motion skeleton is also defined as a pin location. I do not do any programming or much mathematical if then statements in ProE for such control. Any help would be appreciated

Assigning a point to the horizontal curve then attaching the second line to the point gave me the restriction I needed. Something I had known many moons ago and forgot about.

Yeah,

My suggestions were to split the Line using split point if you only wanted the point to move a certain distance on the line. However with Coincident or point on line in sketcher the point can travel further along or even off the line.
The >,< dim relations will give a warning if relation is violated but will not prevent it from happening but will pop up a message stating the relation that was valued.
Say your sketch dimension is sd6
Line 1| sd6 >= 2
Line 2| sd6 <= 10
As soon as the dim value goes outside range by modify or drag entity. You will get a message about the error
: Line # in section: Constraint has been violated.
/!\: Some constraint relations are no longer satisfied in S2D####.

The only way to forcefully maintain the limits is to use if then statements. Then is given by following line's equation.
Line 3| if sd6 < 2
Line 4| sd6=2
Line 5| endif
Line 6| if sd6 > 10
Line 7| sd6 = 10
Line 8| endif
