Hi Jeff

The reason I didn't try that is because the sharp change in direction is only apparent in the second arc. Looking at this though, it occurs to me that I could do as you have suggested and then use the push/pull tool to bring the "return" back to the base plane.

Thank you so much for your help.

Hi TIG

I tried with circles but was not able to accurately place what I would call the base plane. The arc tool works great for that. If I could just figure out how to go from there, I'd be good. Maybe using the arc as a start and then generating a circle for the second arc is the answer. Do I need a separate plugin for that?

I don't have any trouble creating the 3D model, it's the 2D I'm having trouble with.

Appreciate you guys help!

Hi Jeff

I need (at least I think I need) the second arc because the molding profile takes a turn at the end. I have only been successful in getting it right using the outer arc with the vertical "returns" back to the base plane. Maybe there's another way to do this, but I'm not familiar enough with Sketchup to do it.

OK, based on everyone's help I tried this real quick:

Arc test.skp

What I need is the second arc (first plus 8 inches) to extend to the two vertical lines. Since it won't work adding 8" to the first arc I added 16" and then moved back 8". I don't know why I thought that would make a difference, but it doesn't. Is there an easy way to do that? That'd get me where I need to be.

Thanks.

Hi Jeff

I tried the offset tool but the arc it creates isn't wide enough to cover the 8 inches that I need in the horizontal plane. This gives me an idea though and that is to go from larger to smaller rather than the other way around.

Thanks.

TIG

The hour has to do with the fact that I currently only have 2D and need to do this in 4 layers and each layer has multiple components due to tricking my CNC into doing what I want. This allows me to create the 3D component and machine it in one piece rather than 4 (or more).

As I said, maybe I'm just being lazy.

Hi TIG

For me, the molding profile is the constant. It's the arches that change. And they change because there are so many window variations so everyone is unique. I may not have been clear in what I'm doing but it's the arch that's taking the time, not the molding profile. I have to do at least a half dozen different ones each week. I'm in the middle of a job right now that has 4 different arches on the same house. With my current software it's taking me an hour or so for each one, and that seems too long.

Maybe I'm just being lazy, but in a perfect world I'd like to enter in the inside distance, the arc height (I know I can do that with the arc command) and the part width and get the shape.

Thanks for the tip on the faces. My intent is to export an .stl file for CNC use.

TIG

Not sure I completely understand what you mean but I'll try. How would you suggest that I edit the dimensions? I don't think that the scale function will work well to change things. While some of the values can change (distance between the inner points and arc height), the 8" value is a constant.

Would making this a dynamic component be a decent option or is that also overkill?

Thanks

Hi pilou

Here you go:Arch 44.5 7.25 ver 6.skpColonial 8 inch 3D test ver 6.skp

Good afternoon All

I need to make this shape several times per week and wonder if there either is a plugin or one could be written to generate it.

Arch 44.5 7.25.skp

I am given the inside dimension, the arc height, the inner radius and the width (in this case, 44.25, 7.25, 37.77 and although in this instance it didn't quite work out that way. I made this one by making a circle with the 37.77 radius, added another 8" larger on the radius, made a rectangle of 60.25 by 15.25 located at the top of the outer circle and deleted what I didn't need. Lots of steps and an inaccurate result.

I can do these same steps in other programs but I'd rather do it here because I need to run a molding profile along the large radius edge similar to this:

Colonial 8 inch 3D test.skp

and I`m hoping I can get it done in fewer steps.

Any comments would be appreciated.

Thanks in advance.

Can't find the thread, but look for Cabinet Sense here somewhere. It's a great way to build cabinets with Sketchup. It'll give you all the cutlists you need.

Dropout,
We use Ecabinets mostly for our cabinets but I am intrested in your system.
As for the dxf/stl export plugin.For our thermwood post it reads the layers created in the dxf files.In su layers are for visual purposes.I have to creat groups and name them just as you would a layer for example a outline operation for 3/4 material the group would be named outline z0p75,a centerline cut using a 3/8 cutter plunging 3/8 deep would be another group named centerline d0p375 z0p375 the d is the dia. of the tool and the p=the desimal. pocket cuts ,chaincompout,chaincompin,dadoes are handled in the same way.Thatis for our machine I am not sure about yours. I use su for complacated shapes. Mac1 posted that he used double cad I found the download for it but could not install because the searial number was rejected. maby he could help out with this.

I use this for cabinet design: http://forums.sketchucation.com/viewtopic.php?f=80&t=32789&hilit=cabinetsense and Paranest to lay it out: http://www.cabinetpartspro.com/OtherProducts.aspx . Cabinetsense has the proper export that imports nicely into Paranest which lays the parts out on whatever size sheets you want. This will not handle holes, curves or dadoes though.

Dropout,
I am using the plugin export dxf/stl downloaded from the ruby library.By the way what type router are you cuttin with?

I am running a Gerber Sabre router. I have the same plugin but I can't get it to work properly.

Are you doing mostly cabinet work? If so, there is another combination of things that I use that works well. It doesn't handle holes or curves though.

Hi Scott

Not an answer, but what are you using to export dxf files? I'd like them for my router.

Hi Gaieus

I tried to upload again this morning. No luck again.

Thanks for the instructions. Works fine now.

I click on the upload tab, browse for the file, wait a few minutes while the the browser says it's contacting sketchucation. The screen flickers, all the words in this pane are gone and nothing has been uploaded. Start over again, same result. So far 0 for 6.

Can't seem to upload the sink.

How do I auto cut?

Good evening All.

I am modelling a kitchen but can't get the sink to work. I imported a sink from the 3D warehouse and dropped it on the counter. Unfortunately, the counter cuts through the sink. How can I get the sink to cut through the counter top?

Hi All

I want to model some canoes. Any boat hull tutorials anywhere?

What are the best plug ins for this?

I mostly do cabinets and square stuff so I really need help.

Thanks.
