Closing sweeps ends

Recently, in my work I have to do a lot of sweeps, like the one bellow:

Now, to close the ends I have to do a revolve:

PRT0014+%28Active%29+-+Creo+Parametric_2014-09-09_23-47-30.png

This doesn´t seem much work, but, to do the revolve it takes about 23 clicks (Revolve, Select Plane for skecth, add references, define axis, project, trim...) for each end. Total of 46 clicks for closing both sides.

I´m trying to figure out a easier way to do this. I tried copy/paste and udf´s , but both fail often.

Ok, I found a solution, maybe can be shortened a little but it´s the best I´ve got for now:

1 - Do the sweep

2 - Copy one end surface

3 - Trim it by half (by plane)

4 - Copy all edges of this surface

5 - Create a revolve using this edges

6 - Repeat in the other end.

Grouping it all together I just have to give 4 references for each runner: a curve, one end, other end and a normal plane.

I reduced from about 50 clicks to 5 or 6. Good enough for me.

If you don't mind a small pip, a round does pretty well.

...and it can be C2 continuous.

Since this is a channel to be milled, I have to keep the profile (angle and radius):

I got to this within a few hundred... maybe a 1,000 clicks

Only few hundred more clicks might have achieved round'r ends.

I'm proud of it though... fully bound with curvature contraints!

Of course, you could sweep the 1/2 profile around the periphery .

You do not have the mold design package I am guessing?

Yes I have, I can create runners with it, but...... the runner only allows to create cuts, not create "extrudes", I need to create the solid of the runners first, and then make a cut-out.

Also the runner feature seems to have some bugs.

Ahhh, runners. Remember when you got a plastic model to put together, and there was more total material in the runners than the parts?

    That was my initial method as well, Jose, but I ended up with 23 clicks on each half. Since you mentioned 22 clicks per half, I assumed you used the same method. However, that copy/paste thing is nice

    Sorry if I wasn´t clear enough. My target is to replicate sweep and revolved ends with minimum number of clicks/references. Ideally, creating a UDF that only asks for a curve and a plane.

    I started with the sweep and then creating a revolve at the ends. But to do the revolve, I can use only half of the section, projecting the edges, creating a line in the middle and trimming the curves.

    No problem until this point.

    Now I try copy/paste to the other end, it asks me all the edges references, and it fails often. I do the revolve manually again, group all features and try to copy/paste using other curve, problems....

    I try to copy revolved ends to other sweeps with varied dimensions, problems...

    The trick here was to copy the surface, trim it by half, and use all edges for the revolve.

    Now I can replicate the sweep with revolved ends just giving a curve, a plane and two endpoints.

    I have parts where I have to make twenty or thirty sweeps like these, now I make them much more faster.
