Correcting fillet

[bilico]

hello

How can I make sure that a very thin fillet is done perfectly?
Is there any analysis tool?

another doubt:
Is it more appropriate to create an object with polysurfaces than with boolean if I want to apply the fillet later?

thanks

How do you define “perfect”?
ShowEdges with Naked edges selected will highlight any naked edges, ie where the edge of a surface is not joined to another surface.
Continuity of the fillet with adjacent surfaces can be checked using Zebra, EMap (I prefer the fluorescent tube) or EdgeContinuity. Circular arc fillets should be G1 (tangent) continuous.

In general if Rhino creates a fillet which looks correct without obvious gaps or overlaps it usually is correct.

@bilico

Is it more appropriate to create an object with polysurfaces than with boolean if I want to apply the fillet later?

This question is confusing.

A polysurface is a geometry object made up of multiple NURBS surfaces which are joined together. There are many different ways polysurfaces can be created.

The Boolean commands in Rhino are essentially macros which combine trim/split and delete operations. The results of Boolean operations are usually polysurfaces. There is no “Boolean” type objects in Rhino.

Have you had recent problems with fillets? If so post a .3dm file with the geometry and someone will probably help.

Is there a way for an object, for example: a cylinder or sphere, drilled with trim or boolean, to return to its previous state?

Is there non-destructive modeling in Rhino 8?

thanks

Try _Untrim

Undo or UndoSelected may work if the project has not been closed since the trim or boolean was done.

If those don’t work try Untrim. It can be more complicated if the object was previously split or trimmed. See Is it possible to delete this Booleen Differance cutout from the solid? - #2 by davidcockey
Also it can useful to DupEdge any trimmed edges or DupBorder before Untrim. Then use the duplicated edges to trim the untrimmed object as needed.

Untrim may not work if ShrinkTrimmedSrf was used after the object was modified, or if Split with Shrink=Yes was used.

Not as advertised for some other modeling software.

A very good practice is to frequently save the project with incremented names. You can use IncrementalSave Rhinoceros Help

Not really, Grasshopper, the nodal interface of Rhino, might help you model more parametrically.

If not, as other have said, old school way. Save multiple files at different instances, or create a step by step inside your file, copying your geometry into a new layer or a new position each step of the way.

There is an addon for Blender that does this with just one button.

Is there something similar for rhino?

another question :
Where can I find plugins for rhino?

Save incrementally? If so then:

Undo or UndoSelected

Is there a way to save the Undo and UndoSelected list to use it after closing the file?

it could be via plugin.

thanks

Do you believe that editing, for example: applying fillet, etc., to an object created with Boolean is as efficient as editing an equal object created by other means?

thanks

@bilico There are no fundamental changes in Rhino 8 compared to previous generations for what you call non destructive modeling. If that’s what you are looking for, there are many alternatives on the market that will suit you better. What type of models are you trying to build/edit?

These last two posts are independent of the other questions.
I should have opened another topic but I found it more practical to use this one.

Do you know how to answer these questions:

Is there a way to save the Undo and UndoSelected list to use it after closing the file?

In general any object in Rhino, apart from a few smart history chained objects, is an equally dumb object. So whatever you fillet is equal in that sense.

Not that I know of

Well, in most cases “correcting a fillet” means extracting the affected surfaces, untrimming them, deleting of some unnecessary geometry, adding new surfaces and fillets… The process is totally manual and time-consuming. I just did something similar to a model that needed some small modifications. Lots of mouse clicks and use of the best Rhino plug-in made by @jim that could be downloaded from the following link:

Filleting Tangent Surfaces

For those Rhino users who use the FilletSrf command and would like the process to be a little less tedious here is a Python script that will make strings of fillets that expands FilletSrf capability when filleting tangent surfaces: FilsrfEX.py (40.1 KB) This script works the same as the filletsrf command - just pick 2 surfaces that you want to connect by a fillet. The difference is the script will continue to make all the tangent fillets connected to the first fillet until it runs out of tangen…

It’s a good practice to save numerous versions of each important model in a dedicated layer, so that it will be easier to use an earlier version as a base for the modified end model.

Thank you for your help

Do you know where I can find “modeling” plugins as efficient as the one you mentioned?

thank you again

[bilico]

Is there any resource that displays the maximum fillet that we can use on edges without creating defects?

Is there a plugin or script for: unfillet?

thanks
