This is a possible workflow with SU's native tools supposing you already have a cone as a start.

[aea]

thanks , Another problem I found here

[Gaieus]

From the picture it seems that those diagonals could be safely deleted. Try to run the plugin after that.

For rounding the tip of a cone, I suggest you use Massimo's method.

With RoundCorner, you can do the rounding, but:
1) you need to make the edges plain (i.e. non soft, non smooth)
2) the edges will be themselves rounded, which won't leave the surface of the cone smooth.

Also, for the cone, you can truncate the tip and apply round corner only on the top circle. It's a bit of a fiddling around what settings to use but the result will be fine.

Hi,
thanks for this great Plugin.
But i have a problem.
I have a structure buil also with holes.
When i round the corners of the whole structure it closes
my holes on the side where i pushed the form thru the material.
I hope you know what i mean.
When i make a hole i start makin a circle on the Material.
Then i push the Circle thru the material that i get a hole.
Wehen i then try to round the corners the hole is on one side closed.
On the other side not.
Maybe it depends on me.
Or do you know that problem.
Thanks in advance
Best
Walter

Problem of closed holes is known but difficult to handle because it is Sketchup closing the hole automatically.

Just select the face over the hole and erase it. You should see the round corners underneath.

Hi,
Thanks for you fast answer.
But i don`t know how to erase it.
The Eraser tool don`t function.
I`m new in SU .... maybe it`s easy (think so)
What is an easy way to do it ?

Hi,
But i don`t know how to erase it.

Normally, just select the face closing the hole and press Delete.

Thanks! it works great!

Is great thanks

Someone may want to check into this but I found a conflict with podium 2 plugin and round corners. I had to work through almost 30 plugins to find this. It was on a friend's machine and we noticed he kept getting bugsplats as soon as he would activate round corners. I removed every plugin and started reinstalling every one of them and it crashed when I inserted the Podium 2 folder. Took the folder out, things were fine. Bummer.

Hi Fredo,
I'm trying to use Round Corner in SU8, but any time I will define a corner to round, for example a corner of a cube of 2000x2000x2000mm, Sketchup crashes and switch off..

is there a solution for this?
Tahnk You very much.
Paolo.

A cube that size [2m] should be OK... BUT if you then specify a very small radius or excessively large numbers of segments Sketchup/OpenGL can't cope with the tiny faces [<~1mm/0.01sq"] and it fails - sometimes catastrophically. It occurs with many tools - even FollowMe...
This tininess is exacerbated when already small rounded edges meet at corners and some 'quarter-hemispheres' are made to join them together, because they will probably have very small triangular facets at their apexes, which might then be 'too tiny' to be created !

So I'm guessing that this could be the issue...

Try it with a bigger radius and/or fewer segments and see if that works.
If so, and you really must have such a tiny radius and/or many segments, you can get around it thus:
Scale up the whole cube x10.
Apply the edge-rounding [x10 bigger] to it, so this time the tiny face issue is avoided.
When you are done you just Scale the cube with it's rounded edges down x0.1.
Tiny edges can exist quite happily: it is just the creation of them that causes these issues...

[flycase]

I tried to reduce corners, and tried do use an offset of 40mm on that cube, but no combination of parameters seems to work.. everytime I will try round corner to work sketcup closes down.
Fredo scale works poerfectly.. but I'm starting to think that something is not installed in the right way.. is there a way to remove everything and to re-install?

[TIG]

Works fine for me with 2m cube and 40mm radius, 6 segments.
If you have many more segments it takes forever to process and eventually the facets will get too tiny at the apexes and won't be made, even 'splat'...

I installed Round edges by Bezier and it works.. I don't know if the calculation engine it's the same..

Before this I experinced, one time only, that the tool (round Edge) run!! I started SU and built a cube, than applied the rounding to one edge without changing nothing (30mm offset..) and it worked it out.. after this everything workrd perfectly and no errors occurs during all the trials I made!!

closed and reopened SU and again the tool crashed... I've neve been able to let the tool running...


Paolo.

[flycase]

Tried to follw your suggestions,

placed a cube of 3m and an offser of 40mm.
Again a crash occurs..

I can send the log file generated from the splash manager.. if you think this can be useful...
thank you TIG.

[TIG]

How many segments does the rounding have ?

[fredo6]

I installed Round edges by Bezier and it works.. I don't know if the calculation engine it's the same..

I would be careful to use this plugin which is quite old and which I don't really maintain (nice to see that it works).

• RoundCorner includes all features of RoundEdges and is more stable.
• The algorithms are also different: RoundCorner uses real arcs of circle (as well as Bezier curves), whereas RoundEdges is based on Bezier curve only.
• RoundCorner does real rounding and treat concave corners. RoundEdge has only the 'sharp corner' method.

[flycase]

The rounding have 6 segments, I tried with 3, with 1, with 10...
no differences..

I' still thinking to the only time it worked... it' really amazing...

Rounded Corners.png

This is an amazing tool! I like the parameters, navigation and selection/deselection through the whole process. Well Done!

Is there any way to use it to fillet cylindrical features to flats? I'm trying to fillet the inside pocket of a block (aluminum) with bolt holes that have bosses that jet out into the pocket, because the axis of the bolt hole is at the intersection of the insides of the pocket. I've looked at a couple of other plugins, but they all seem to gap the fillet along the square boundary containing the arc of the cylindrical feature (like you can see at the top of this part). I suppose I could draw the features square size and round them all with the same size fillet, but this particular part needs to have the boss perimeter at .375", and the adjacent fillets at .250".

Is this the right tool for the job? I am new to this amazing world of modeling. I would also welcome any links or references you have for me to keep the whole process as simple as possible.

Thanks!

Using very small dimensions can cause issues as Sketchup/OpenGL cannot form facets of <~1mm/0.01sq".
However, such tiny facets can exist!
I suspect this might be the case here...
If you are making forms with small facets [like the 'apexes' of the 'dished' shapes] then the fix is to Scale up the original object x10, do the processing [remembering to adjust its values x10 too!], when done you Scale the object and the new geometry x0.1 and the facets will shrink to be tiny, BUT they'll be OK - because it's the 'making' of them that's the issue not their actual 'existence'.

[gilles]

in some cases try follow me tool.

[TIG]

The 'small facet issue' also appears with FollowMe, so whichever tool you are using remember the scaling-up/down 'trick'

[fredo6]

@mechblack,
Maybe you could post the model so I see what is the problem. It might be that the dimension of the rounding are too big for the geometry to close nicely.

Hub - Fillet all the web features.skp

Block - Pocket with inside bolt hole bosses 2012-01-27 330pm.skp

It is great to find so much help!

Fredo6, here is the model.

gilles, your solution is elegant. My trouble with the 2d fillets has been getting them to join the circle with the line, as shown on the block model. I'm also coming up against issues like filleting the webs on the hub. Fredo6's tool almost works like Solid Works's (Dassault Systèmes). I plan on practicing more with SketchUp this semester. I want to know if there is a cost effective alternative to the giant programs with the giant price tags. It may come down to practice, practice, practice, and just learning to effectively use the simple tools that Google provides. Of course, it helps to have amazing programmers, plugins and contributors (like are found on this site).

Thank you all!

[fredo6]

Fredo6, here is the model.

As evoked, the issue is purely geometrical. The radius of your rounding is too large compared to the shape, so that you will necessarily have overlaps. I could make it work for a rounding of 0.2cm max.

Solid Works is based on Nurbs. This gives much more flexibility to merge curved surfaces. RoundCorner is purely geometrical and cannot manage the overlap cases.

Have a good practice

Fredo, this was probably asked before, but I didnt find it in this very long thread. Neither I found the answer in the quick manual.

Check the image attached... the offset somehow overlaps itself. It happens quite often when I try to use your tool. And when the offset overlaps, it usually results in problems in the end.

How do I solve this issue?
