Stretching a "dumb" part

[jfleming]

Hello, I have an imported STEP file from a vendor. Picture it as a dumbbell and I want to lengthen or shorten the "handle" in the middle. Is there any method for accomplishing this, while leaving the "weights" out at the end unchanged.

My only solution is to boolean subtract one half, save as X. Boolean subtract the other half, save as Y. Go in and make an assembly with a new piece in the middle and make it the new, correct length???

Left side ->2D Sketch rectangle -> Cut -> Save (Part 1)
Right side -> 2D Sketch rectange -> Cut -> Save (Part 2)
Close
New Assembly - Insert : Part 1 + Part 2
Create / Insert a new Part 3 in the middle.

Have a look at the "Direct Edit" tool set

Nothing there allows for a "mass grab" of the entire "end" of the part to pull it all at once.

Push/Pull Boss can work with a simple dumbbell. Not sure of limitations if the shape gets more complex.

I have a long rail with this same thing on both ends. need to shorten the rail.

Direct Edit > Push/Pull Face Or Sketch
Choose face of rail. Input the distance you want to move it.

Redraw part.

My approach for what it's worth.
Change extrusion 1 length to mod the part.
Hope this helps.
