How can I do this with 3ds MAX?

[Anonymous]

This is something I need all the time and I have not found any easy way to do this in Max.  Can someone help?
Extend face (software: FormZ)

I cannot think of an easy way but here's my first try.

With snaps set to Edge/segment create a line along each edge that want extruded (red lines). Now move these lines along their edge and then create create a closed line between the 4 line ends (blue line).  The closed spline can then be extruded to the correct thickness and unioned.

Not simple but it works.  A simple script could simplify this process a bit.

I created the following simple script to simplify the process I outline above. 

Run the script after creating the 4 vertex red line to get the closed green line.

--  A 4 vertex colde spline is create from a selected 4 vertex spline such that
-- a new vertex is create in line with vertices 1 & 2 (e5) and 3 & 4 (e6).  
-- The distance from e2 to e5  = e1 to e2.
-- L. Minardi  1/11/2019 
-- 
for spl in selection where classof spl == line do (
s=1
e1 = getKnotPoint spl s 1 
e2 = getKnotPoint spl s 2
e3 = getKnotPoint spl s 3 
e4 = getKnotPoint spl s 4
v12 = e2-e1  -- vector from vertex 1 to 2
vlen = length(v12)
v12u = v12/vlen  -- unit vector
e5 = e2 + v12u*vlen
v43 = e3-e4
v43u = v43/vlen  -- unit vector
e6 = e3 + v43u*vlen

local sp = splineShape()
addnewSpline sp
addKnot sp 1 #corner #line e2
addKnot sp 1 #corner #line e5
addKnot sp 1 #corner #line e6
addKnot sp 1 #corner #line e3
close sp 1
updateShape sp
select sp	
	)

A little explanation on Video...

And here if our parts are completely  separate Objects...

Thank you very much for the reply.
I was hoping for something that did not involve so many clicks as this is a repeating task in some of my projects.

Thank you very much for the reply and the time you took to explain your solutions.
I have been using the quickslice tool in almost the same manner as you described, but I was hoping for something that did not involve so many clicks as this is a repeating task in some of my projects.

Hey,

may I ask you first for what you need this "all the time"?

Because to me it doesn´t seem to be something many modelers would use all the time.

Also I would like to know if your final result should be connected or be 2 different objects/elements?

Here a video about the solutions I would use. Hope it helps:

About a mistake in the video: It´s transformation coordinate center of course and not system
