[밑에 질문 참고] 인벤터에서 파이핑하기






안녕하세요, 인벤터에서 파이핑에 관련된 내용을 정리한겁니다.

참고가 되길 바라겠습니다.

Q: Making an Adaptive 3D Pipe in the context of an
Assembly (1012)

A: In this example we will create a fully adaptive 3D
pipe in the context of an existing assembly. We will utilize heavily the use of
in-line work features so that after we are complete we can adjust any of our
assembly key locations and our pipe will update accordingly. color=#000000>

Below is the sample pipe we will make. The run will start
at the green node, pass through the vertical support, then pass through the
center of the square cut-out and lastly connect to the red node. The position of
any of these features can alter and have the pipe run update
automatically.



Before we begin, make an assembly similar to the 3 parts shown. The green and
red parts can be the same part if you wish. Size is not important.

Step 1. To begin, at the assembly level, we create a component called wire1.
The “Constrain to Sketch Plane or face” setting should be on in our case. This
part will be placed on the front of the upper green node.

Step 2. We will first sketch our wire cross section as a circle. To ensure
alignment from the green node, we use a cross part associative projection from
the green nodes circle resulting in a pink associative circle. Then we offset
our wire diameter profile inwards from the pink circle. The intended wire’s
profile is shown as the black circle below. Once complete we exit the 2D sketch.



Step 3. Now we must begin to create our path and to do this we must enter
into a 3D Sketch. Once in the 3D Sketch environment, we will build our path by
first constructing a series of adaptive workpoints which will be connected with
lines and radii to make the entire path.

Step 4. Our first point will be at the center of our circle. Since the circle
is part of our local part, we will simply use the include geometry tool to
select the circle’s center point. This point will now be selectable later on
when we connect the dots.

Step 5. Our second point will be at a location away from the node but axially
in line with the first point. To do this we will use in-line work features. We
start out by selecting the workpoint tool. As we know, a point can be defined by
a plane and an axis. Since we have neither a plane nor an axis passing through
our intended location, we make them in-line by using context menus. With the
workpoint tool still depressed, right click and choose “Create Axis” then select
the cylindrical body of the green node. A yellow preview will precede selection
followed by a faint axis representation in green. We’ve defined our axis, now we
need to define our plane which is an offset of 0.25 from the end of the node.
Next right click and choose “Create Plane”, then select and hold down on the end
face of the node and then drag rightwards. An offset dialog will appear and we
enter our value of 0.25 as shown below. As soon as we select the check mark, our
work point will appear at our intended location being offset 0.25 and axially
aligned with the node.


Before we move on to our next workpoint, lets examine our browser to see what
really happened there. As shown below, our workpoint is present within the 3D
Sketch and within that workpoint are the 2 in-line work features we used to
define the point. Both these in-line work features are adaptive in nature so
that of the source object move or change, these will update accordingly.



Step 6. Our next work point will be at the entrance to the vertical support.
Again we will use in-line work features to create this point. We are after the
combination of the supports front face and the holes axis. We start the
workpoint tool again, we right click and choose “create axis” and then select
the inner face of the hole. Next we simply satisfy the workpoint’s needs by
selecting the front face of the vertical support. This causes a workpoint to be
created at the yellow X shown below.



Step 7. We repeat the last workpoints process except this time we use the
rear face of the vertical support. This gives us another workpoint at the exit
location for the pipe.

Step 8. (the hardest one) Our next workpoint location is to be at the top of
the square cut-out of the plate. Again there exists no work geometry or points
to select so we will build them in-line. We will build on the basis of making a
point between the top face and an axis up the middle. The axis up the middle, in
turn will be built based on the intersection of the 2 diagonal planes that run
in the direction of the cut. We do this by creating multiple levels of in-line
features.

Start by pressing the workpoint tool.
Right click and select “Create
Axis”
Right Click and select “Create Plane”
Pick one inside vertical
edge of the cutout.
Pick opposite (diagonally) inside vertical edge of the
cutout.
Right click and choose “create Plane” again
Rotate model for
clear unobstructed view of hidden vertical edge
Pick new inside vertical
edge of the cutout
Pick opposite (diagonally) inside edge of the cutout

(these 2 planes we defined now define the axis we needed so all that remains
is the top plane)
Pick top plane to complete and the workpoint is placed at
the location of the yellow X below.



Upon examination of that last workpoint in the browser we see the multiple
levels of nested work features.



Step 9. Whew!, that was a chore, so lets make the next one a bit easier.
Since we already have one point in the middle defined, lets create a workaxis
through the point and normal to the top face. Select the workaxis tool, select
the point and then select the top face.

Step 10. To create the next point at the bottom of the cutout, we simply call
the workpoint tool again, select the workaxis from step 9 and the bottom face of
our plate. The workpoint will be created as previewed at the yellow X below.

width=191>

Step 11. Our next point is to be created created axially aligned with the
upper red node and offset by 0.25. Again, using the techniques mentioned in Step
5 we create this workpoint.

Step 12. Our last workpoint is place on the center of the red node. Using
techniques in Step 6 we can place this easily.

Step 13, (the fun step). Start the line tool and begin connecting the dots.
You will see radii automatically added as you connect the dots. In the event
that there isn’t enough length to accommodate the radii that’s being applied,
you will see a symbol previewing that no radii will be added at that location as
shown below. Just keep on connecting the dots to complete the path.



Step 14. If you want to add smaller radii at the locations where no radii
were added, use the “bend” tool, supply a smaller radius and add bends where
they are missing.

Our path is complete and all that’s left to do is to sweep our pipe.

Step 15. Exit the 3D Sketch mode and run the sweep command. Select the black
circle from step 2 as the profile and our 3D sketch as the path. Press OK and
your done.



To test your pipe, edit any of the parts and adjust the location of the
nodes, cutouts, holes etc. and see your pipe update.

    2. 감사합니다..
      궁금증이 풀렸네요…
      그런데…너무 복잡한것 같아요..제가 예상했던것보다 훨씬요..
      이렇게 해야한다면..복잡한 그 많은 배관도을 어떻게 다하나요
      이 방법 말고 다른 방법은 없나요?
