NEW Copy geometry (sweep) problem

[dpasa]

Although the previous problem isn't solved, (the answer I got didn't work, anyway I made the same thing twice, no problem) I go on to the next one.
Again the same picture, showing a void sweep.
Now I want to make similar sweeps on the curved part of the wall. The problem is that you need a working plane to make the 2D path. How can I select the curved surface? It doesn't seem to work no matter what I try :-(

Hi Dpasa,

You don't need a working plan to make a sweep. Just pick the 2D path in plan or 3D view, then sketch the profile.

Even easier is to use "Host Sweep".

Give them both a try.

Thanks beegee, but I can't make it work...

Host sweep makes a horizontal or vertical sweep and not a rectangular shape as I want. At least this is what I have seen so far. When I try to use sweeps from Create->General model->Solid->Sweep I can't lock on the curved part of the wall to sketch the 2d path.

Is there any other way, am I missing something ?

You can place host sweeps for the horizontals and drag their ends to create the width you want, but it can be difficult to drag the ends of a curved sweep accurately and they don't want to align either.

There are a number of ways this can be done, this is just one.

Place Rps to define the horizontal and vertical extents for your sweeps.
Place a horizontal seep , using the curved wall face as the 2D path and sketching the line between the two vertical Rps. Draw the profile at the top and the bottom in a section view. ( To do this you need a section snapped to the center of the frame )

Place an extrusion for the frame side, picking the bottom sweep as the work plane and extending to the top frame. Finish sketch, then mirror this extrusion about the center RP.

Thank you for your time beegee.
I guess that practically it can't be done. I was expecting a small tip and you are describing something that reminds me of solid modeling in AutoCAD. I hope we will see some improvement on that kind of problems in the future.

Thanks again

It is a common feeling that because Revit makes so many simple things even simpler, that things that are actually quite difficult should be simple too. beegee's workaround is fine, not all that laborious and really only one way to do what you are trying to accomplish, but the first thing you need to do is become more familiar with the tools he is describing before trying the overall solution that he suggests. That way it will seem less overwhelming and more intuitive.

I guess my point is, trying to solve these problems using the tools at hand is actually a very good way to become a Revit poweruser. You will try a number of different methods and learn about the limitations and capabilities of them all so the next time around you will be that much more proficient.

Finally, expecting Revit to have a special command or method to do everything is unrealistic. If it really can't be done, then I would agree that there needs to be some improvement to the tool, but my guess is that there is more than one way to skin this cat.

I'd recomend building wall-hosted famlies for these. That way you can precisely contol placemnte and also change the proportions all at once.

Here's a quick example.

Thank you all for you answers.

I don't expect Revit to do everything simply by executing a command. I was just wondering if it could be a simple way of doing such things. That is because I use this kind of sweeps/reveals almost every time so I would like to see something fast and easy...
Of course I want to be a Revit poweruser but I have to continue working at the same time because my clients won't care which software I use, the drawings must be delivered on time.

I hope it will get better near Christmas and I will be able to learn more. Actually I learn something new every day.
