Sketchup - Extruding Curved Faced into other Curved Faces?

Doug, I am sure that DaveR will chime in on this. He is the resident Sketchup expert on board here.

Doug,

Scott was right. I will chime in. I’m not sure that I’m the resident expert but I’ll try to help. Are you referring to drawing the cope and stick profiles on the ends of the rails? If you can give me a little more detail, I’ll show you how to do what you’re after.

Thank you Scott.

Dave

Doug, I will be interested in seeing Dave’s response to this. It sounds like you are having a problem that I do as well. Trying to put a round over, for instance, on mitered joints just does not work with the push/pull tool. Just guessing I would say it probably involves using the follow me tool but I am still trying to get familiar with that function.

Is this similar to what you’re trying to draw? Scott, is this the kind of thing you’re thinking of?

Daver,

Yes, that is exactly what I am trying to do.

Ok. you can’t do that in SketchUp. Just kidding. I’ll make up the steps for you and post it in a little while.

No doubt in my mind Dave you are the resident expert. Great job what you can do with sketchup always amazes me.

Thanks Jim,

SO here we go Doug.

Make the rail and stile components. Profile the edges of the the rail using Push/Pull. Do the inside profile on the stile but don’t worry about the outside for now.

Scale the model up by a factor of 100 or so. This helps prevent missing faces that can occur when tiny faces are formed Copy (Ctrl+Move) the stile component and move it into place at the end of the rail. Explode that copy, select all of its geometry, hit Ctrl+X, the scissor icon or Cut from the Edit menu. Open the rail component for editing and go to Edit>Paste in Place. Select all of the geometry now inside the rail component. Right click on it and choose Intersect>Intersect Selected.

Delete the unwanted bits. I’ve started that here.

Finish deleting the unwanted bits and then correct face orientation as needed. there should be no back face color showing when you’ve finished.

Now to profile the outside edge of the stile.

Draw the profile on the end opposite where you were just working. Select the vertical edge and the top edge of the stile as shown in blue here. Get the Follow Me tool and click on the profile.

The round over will stop at the edge of the inner profile.

Get the Push/Pull tool and hit Ctrl. Then push the profile face out past the inner profile. Select all of the geometry and run Intersect>Intersect Selected as before. Delete the unwanted geometry.

You’ll end up with something like this. Delete the short line segments running up over the curve. Leave the horizontal lines alone. They should take care of themselves. If they don’t get soften, you can do that with the Eraser tool.

You’ll end up with the completed cope and stick joint. If you wish, soften the edges at the limits of the curve.

Now, I bet you’re wondering what to do with the opposite ends. You could repeat the first part of this on the opposite end of the rail. There’s another and I think easier way. Draw the rails and stiles to half their final length when you start. After you’ve finished the above, open each component in turn, select all of its geometry and copy it with Ctrl+Move. Drag the copy away. Horizontally in the case of the rail and vertically in the case of the stile. With the copy selected, right click and choose Flip Along and flip that geometry to mirror it end for end. In my example here, that would be along the red direction for the rail and blue for the stile.

Then move the copy so the flat end meets the flat end of the original. Delete the ‘seam line’ around the middle of the part and you’re finished.

Certainly once you’ve drawn the entire thing, there’s no reason to ever draw that same profile again. You can simply resize the existing components to fit any door size with the Move tool.

Howzzat, Doug?

Looks Great! Easy, too! I’ll give it a try, and let you know how it works out.

How do you insert the illustrations into this thread?

Glad that seems to work. I put the illustrations into my Flickr album and then copied the HTML code for each image and pasted it into my reply. If you click on the images you can get a larger version if you want.

FWIW, there’s a slightly easier method but this was easier to show in still images.
