Issues with OFFSET > Projected Geometry

[blackwater_hollow]

Hello,

 

I am having issues offsetting a Projected Geometry Line to a specific distance away from the original line. I was successfully able to offset the PG line to a max distance of .017", but I need it to be .125" away instead. I have tried to edit the distance from .017" to .125", but Inventor returns an error.

 

 

Yellow Line : Projected Geometry Line

Blue Line : Offset Line

 

I am not sure how this Offset Line is constrained, and I am pretty sure the middle valley curve is what is causing all the issues. I tried to Split the line, but because it is constrained, it really messes up the shape.

 

If anybody has any suggestions on how to offset this line further, please let me know! Could the constraints be relaxed or broken? I am spinning my wheels here on this one!

 

Thanks!

Do you realize that the curve would cross over itself? Is that what you really want?

Hi JD Mather,

 

Thank you for the quick reply.

 

On another attempt that I made offsetting the projected geometry using the loop select, I was able to offset the lines to the required .125". However, the overlapping occurred just as you had said. I am okay with the overlapping if I am able to either Trim or remove the overlaps.

 

Here is what it looks like:

 

 

This is what I want it to look like: (Edited in Photoshop)

 

 

Do you have any suggestions on how I may remove the overlap areas that have been circled with red? I just need the intersection points of the lines to be changed into fillet radii.

 

I have attempted to trim the overlap away, but I am unable to choose some of the lines. I attempted to convert to spline, and edit the spline, but it changes the geometry too much.

 

Any help or suggestions would be greatly appreciated!

You can select the loop too offset, click right mouse button, and uncheck "Constrain Offset". Then constrain and trim how you see fit. Another way is to leave "Constrain Offset" checked on, and just delete the curve that would overlap, and trim/extend to connect the adjacent curves. This will break up the loop into multiple parts. You will have apply multiple offset dimensions along the broken up loop. Or offset each curve individually, right mouse button and "Unckeck Loop" select.
