Round Corner Issues

Postby patrickjohnkelly » Tue Apr 17, 2012 6:41 pm

I'm having trouble rounding corners in Sketchup 8 using the Round Corner plugin (LibFredo something).

I've attached 3 images to show you what I'm trying to do.

I need the corners to be rounded at least 5/8" and when I try it gives me extra strange geometry. When I try to delete the geometry it leaves gaps that I don't know how to fill.

Any help would be appreciated!


Thanks,

Patrick

Two options come to mind. Reduce the number of sides used for the roundover. Six is surely enough at that size. Also scale the model up by a factor of 10 or 100 before rounding to avoid the tiny face problem. My preference is to make a component before doing anything that would cause the tiny face issue. Then I make a copy of the component and scale it up. After performing the rounding (or whatever) I close that giant version of the component and delete it. this leaves the original in its original location with the faces all taken care of.

So after trying what you suggested, it seems that even still at 10 or 100 times scale it will still add the extra geometry. When rounding perfectly square corners it seems to work totally fine.

post the .skp..

you likely are telling sketchup to create geometry which it isn't actually capable of doing..

hard to tell from your screenshots without hidden geometry showing.

Haha, definitely a possibility. I'm quite new at this. Here is the SketchUp file! If SketchUp isn't capable of creating this does that mean that I'd have to move up to a more complex program like AutoCad to get the right results?

Thanks again for the help!

Would this make enough rounding?

Your top part has too much geometry. Here's a reduced version.

That looks great! It's just supposed to look like a couch cushion so that should be enough rounding! How did you achieve this?

Thanks,

Some notes... Turning hidden geometry on shows that you have unnecessarily dense geometry here and there. I cleaned those up. There is a region on the back, too.

Then there is this preview tool for this plugin. It seems 1" will cause issues with geometry...

Cushion2.png

So I turned it down to 3/4" where it already shows that it will be okay. Then 6 segments is way enough for such a rounding (generally).

Actually, 3/4" is still a bit much. I used 1.5cms which worked. Finally here is a bit cleaned up version.

That makes sense to me about cleaning up the unnecessary geometry but how do I go about this?

Either manually or with some Cleanup plugin:
viewtopic.php?t=22920

Here I actually did it manually. You can select those edges that are apparently not needed there with a left to right selection box then press Delete.

One thing that will help with the cleanup stuff is to try not to make the excess geometry in the first place. Out of curiosity, how did you create the basic shape for this cushion to begin with?

To be honest I can't even really remember how I made the shape anymore. I've been teaching myself as I go on this couch model and just sort of using trial and error to figure it out as I go. This is my first real sketch up model that isn't a tutorial. I still can't seem to figure out how to simplify the geometry near the top on the front where there are about 10 small sections. I downloaded CleanUp3 and as far as I can see it's not changing anything regardless of the settings I choose. I'm sorry for my lack of understanding because I probably skipped passed some very basic stuff that I should have known from the start!

No need to apologize. We all started somewhere. Sometimes the problem with software is that you can't look up the solution to a problem because you don't really know what the problem is. It's like trying to find b in a+b=x.

So you really can't get rid of those lines at the top unless you want to straighten out the top front surface. That's why nothing appears to change. Those lines seen there are required to create the faces.

Since this is a learning process for you, you might consider starting over. The next time around it should go much more quickly now that you know the problems.

That part also bends a bit. Delete those edges as well as the arcs on the sides and simply redraw single edges there

Awesome, finally got it. Thanks a lot, guys! I'm also having one insanely frustrating issue with sketch up where the zooming in/out will just randomly not work and just barely move for a random amount of time until it just decides to work again. Have you ever had this issue?

The zoom thing is sort of a designed feature. It depends upon where the cursor is. if it is hovering in empty space the zoom function tends to be slower than when you're hovering over geometry. Distance to the geometry influences it, too.

Re: Round Corner Issues

Postby rstanley » Mon Jan 01, 2018 6:00 am

Am trying Round Corner and cannot seem to get it to fillet the intersection of two intersecting cylinders whether at 90 deg or off angle. I explode both and intersect faces to get this result with hidden geometry on, offset set at ½" with the smaller cylinder dia of approx 6" :

Round corner will nicely round the ends of the cylinders but it will not fillet the intersection of them. Same thing happens when intersecting any curved surface with another curved surface... In every case, I get the red hashed circle and yellow arrow saying "invalid not 2 faces but four".

running a macbook pro with OS hi Sierra with a very recent download of Fredo 6 on skp pro 2016.
Help
Thanks in advance

It's not a round corner issue , it's a scale issue. Need to make the parts your wanting to fillet a component, make a copy and scale the copy up. Run Roundcorner on the scaled up copy and it will work fine. Attaching image , large pipe is 6" dia., small pipe 4"dia. I worked on a copy scaled up 500%.

Tuna thanks for that trip it but no luck same yellow arrow red hashed circle saying invalid corner (at least not with the (four corners not two message through). I made a component of the smaller 4" & 6" tubes scaled the copy up to 16" and 24" did respectively, exploded the image, with hidden geometry on then intersected edges with selection, then attempted round corner again. same problem. Have included the settings for round corner fyi. Thoughts ?

There are some situations which Round Corner won't handle well. This is one of them.

How will you be showing this model? You might have better luck if you use Bevel instead of Round Corner. It will at least read as a fillet.

If I use your offset and segment count settings I get an error message that there are "multiple overlaps". Do you need to have a 1/2" offset ? And why 24 segments? Reran a test, 6" dia. vertical pipe, 4" dia. horizontal. Without scaling up ran Roundcorner with 1/16" offset and 3 segments , Roundcorner ran fine. To get a larger offset I needed to scale up a copy and work in that.

Hi Tuna,
Ok, I just tried reduce segments of the intended fillet to 4 ( down from 24) on both the scaled up image and the original image ; I then tried using ' bevel' for fillet instead of round fillet. Am still getting same error message yellow grow red hashed circle. Tried changing edge filter from line to dashed to hidden; no luck . I then tried changing angle intersect tolerance from the given 30 deg to +/- 10 deg; No luck there either.
If it is working for you and not of me then its is something different in our OS or fredo. By the way, I can easily still us round corner for end rounding and even filet on intersect of a cylinder with a flat plane whether normal, or inclined to the cylinder. It seems to have to do more with the compound curving ring generated by the intersect of a round surface with another rounded surface, not a scaling issue not a curve segment issue thus far at least...Thanks for sticking with me on this .

re filleting of two intersecting cylinders in round corner; This may explain why I am uno le to fillet intersecting curves.

Fred notes that round corner creates (fillets or rounded or beveled edges) corners between 3d objects and 2d surfaces:

Screen Shot 2018-01-02 at 4.58.37 PM.png


How you are achieving this by your recommend scaling action, must have to do with tricking the filled round to the next faceted ( 2d) surface of the mating 3 d object i.e. the other cylinder.
IS this making any sense?

the truth is somewhere between us eh ?

It sounds like you simply haven't removed the internal geometry.
When you intersected the two cylinders did you go inside and remove the excess?

DAVE R SCORED A HOMER ¡ Thanks. It was not a scaling or side count issue nor was it a round versus bevel edge choice, Nor was I correct in assuming the 2d plane to 3d surface limitation for round corner. It was simply that the intersection had to be cleaned of any hidden extension of in my case the smaller cylinder as it passed inside the larger cylinder . Not only Dave, was it necessary to clear the extended cylinder geometry but also-and critically, to clear out the filled curved disk created on the interior surface of the larger cylinder as well. I hope that all other well intended advisors for round corner, please also mention this critical subtlety or erasing all internal geometry before attempting round corner, to their readers. Dave, just for closure, If you don't mind, please tell us how you came to this conclusion . Thanks all for giving it a go and I hope what I;ve learned the hard way will be passed on to all who may run into the same problem.

I think it was Box who scored the run with removing the internal geometry although I did it before creating the example I showed. I kind of assumed you would have done that since that internal geometry isn't needed. In the case of this extension, the presence of the internal faces results in ambiguity. There's no way to tell the extension which two faces/surfaces are to share the resulting new geometry. Removing the internal surfaces eliminates the ambiguity.

Hi, I am having a problem locating the fredo6 round_corner tool in sketchup. I have installed it and it is in my extension manager showing signed with no problems indicated. It appears installed but not usable. I've installed other extensions and working with no problem. I have also installed fredo corner, which is also not working. Any suggestions?
