This is the reason I'm trying to find a 3d fillet tool.Trouble connecting the flats and the circles.

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!

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!
