Inside corner radius path effects

[adbuch]

Does inkscape have a fillet tool?

Yes - that is what TJ is attempting to use. It works great on outside fillets, but I'm not sure it will work for inside fillets. I will check this out later this evening at get back to you.

David

Can't you break the path at the small sides and then they'll both be outside fillets. Then join them back together. I'm not an inkscape expert, so maybe this isn't possible.

djreiswig - take a look my previous post above where I show how to do the inside corner fillet.

Djreiswig, I'm not sure that I understand what you mean by "break the path at the small sides". Perhaps you could draw a sketch to show us what you have in mind. Thanks,

Break the short lines on the top and left of the L. Then you have 2 open paths in an L shape. Both are open contours. Then apply the fillet to each. Then re join the broken paths.
Maybe this isn't possible in inkscape.

David,
I followed your last post. I am going to see if I can try and get it to work. I think this is way too much playing around to make a simple part in inkscape. Again, I am not a node guru. I am sure there are other programs out there that would allow me to do this in an easier fashion. Thanks.

The fillets can be added without breaking the lines. If you take a look at my previous post you will see how to do it. Of course if you don't use Inkscape you are probably using a more "user friendly" program like CorelDraw which will do this very quickly. Thanks for you ideas!

TJ - This is the simplest method I have found to accomplish what you want using Inkscape. Now that I know how to do it, I could draw up your "L Bracket" in several minutes. Very quick to do with practice. Otherwise you might consider Fusion 360, which is free and will do this pretty quickly. If you want I will show you how to do it with Fusion 360. Thanks for taking the time to follow my "tutorial" and let me know if you have specific questions.

TJ - this looks great! I will take a look at your actual file later this evening to check it out in detail. I also had a few other ideas to accomplish with possibly fewer steps. I will try those out as well and report back.

Many different ways to accomplish the same results.

My point was that breaking the lines involves extra steps which are not necessary. But yes - as Tom often says - "there are many ways to skin a cat".

TJ - this looks great! The radius on the two corners don't exactly match, but it is hard to tell from just looking at it. And now that I know that this is a push bar mount, that inside radius really doesn't matter as long as it is a smooth transition - as opposed to a sharp corner.

Here is a comparison of your original file as drawn vs. the edited file with matching radii.

Here it the edited file just in case you are interested to compare them.

Also - here is a quick method to create your part with matching inside and outside radii.

TJ - just for fun I drew your part using Fusion 360. It's pretty easy to do, and you can change your dimensions on the fly by clicking on any dimension and then editing the value in the dimension box.

I exported as dxf and opened with Design Edge to check it out.

So TJ, if you get too frustrated with Inkscape you could always give Fusion 360 a try. It is free and may be worth taking a look.

Wow. I was very close to what you did in the quickest way with the two squares and the "difference" now that is a short cut to the desired result.
Thanks. When I get a chance, I will look at the Fusion 360. I will be cutting out 4 of these plates to make 2 weldments. I will space the plates out about 2" apart and then cut 2 strips the length of each opening and weld it together as a "curved rectangular tube". I was going to do this with Weld "els" but decided to go this route.

Hi TJ - It sounds like you are on the right track. I looked up weld els and it looks like these are pre-bent tubes for welding. You went another route. Yes - as we went along with this project we "homed in" on the shortest way to do it. Lots of thinking and figuring for both of us. You gave me some great tips about path, difference that I had not thought of. I don't normally use Inkscape for these sorts of tasks, but it is good to know how to do it and this may help others looking similar information.

The one thing I don't like about Fusion 360 is that it is "cloud based", and as such is sometimes incredibly slow to load and do certain operations. Inkscape in installed on our computers, and normally responds very quickly - although I have managed to crash it lately trying to do certain operations.

Good luck with your project and be sure to show us some photos of your final result.

As usual with PS member when a question is asked there are answers given. The level of tutorials and discussion is very active.
I like to say when you have a problem allow you mind to wander, the lets see what this does can be helpful.
As David said answering another's question helps you to learn. PS's collective knowledge is getting larger.

[plasmanewbie]

I agree with AC 100%. I have been a member here for many years, needed and received a lot of help at first and now I try to help other new comers as it can be a struggle at first. I don't lean on PS for help much anymore but every time I log in I learn new techniques and see others creative ideas which I find very beneficial. Great site

TJ - Here is another free drawing program that is pretty simple to use. It's a basic drawing program - lines, circles, fillets, shapes, etc. I've had it for awhile now and actually got it for the auto tracing feature. But you might find it easier to use than Inkscape for drawing simple mechanical shapes like the one you just finished.

Here is the download link.

https://www.omax.com/libraries/omax/download/

Here is the online user's manual.

https://knowledgebase.omax.com/protomax ... 0%7C_____0

Here are some very useful software videos showing how to use the program.

https://knowledgebase.omax.com/protomax ... E%7C_____0

I drew a part very similar to yours just to try it out. Then I saved as dxf and opened the file with Design Edge to check it out.

Just another idea for a simple mechanical drawing program.

SolidEdge 2D Drafting is another one I would recommend. As I recall - I think Rokcrler and several other members either use this program or have recommended it.

It has a Smart Dimension feature like Fusion 360 so you can dynamically edit your dimensions as needed.

I find SolidEdge 2D much quicker to use than Protomax Layout - so if you were going to check one out to see if you like it then this is the one I would recommend.

David, I do use SE but I use the 3D version more than the 2D, only because i forget that its there (draft)
The 3D version has both, but the 2D is only 2D.
I too started with Inkscape for tabs and brackets until i realized dynamic changes made it easier in SE.

Rokcrler - in the 2D version do you know if there is a way to save only the drawing portion without the boarder?
Thanks,

Rokcrler - I made the transition from SolidWorks to Fusion 360 a few years ago, and normally only use it for solid modeling for 3D printing. It seems like I remember trying the SE 3D version a while back, but was having difficulty exporting the dxf 2D files - and I also think I remember it hanging up on me quite a bit - so I uninstalled it. Perhaps I will revisit it.

I was recommending the 2D version to TJ as I think it would be much easier to use for him if he is used to doing his work in 2D with Inkscape.

David,
In draft mode, click on VIEW and select 2D, once you have your part drawn, click save as and change file type to dxf and should be good.
