3D Dome Dish Dimple Help

Post by WaltS »

I am trying to create 2 dimples using the dome dish clipart. Currently the dome_dish_45 but I'm not sure that matters. Attached is the preview as well as the settings for the component. Trying to figure out why it has the major jaggy edge around the dimples. I pretty much have the size and depth of them where I want them, but what am I missing? As you all pretty much know, I don't grasp the 3D stuff too well yet. The remainder of the file is using the moulding toolpath, which maybe I should use for this too, but thought I'd try something different. :oops: Using a 1/4" ballnose for the toolpath. File is too large to upload and can't get into my dropbox acct for some reason today. :roll:

If by that you mean the interlocking hearts: remember that the moulding toolpath creates no physical model. Therefore when the 3D finish pass for the dimple reaches the top there's nothing stopping it from "rolling over" the edge.

Needed a vector boundary. Thank you for the nudge! :D

Well , that helped for a moment anyway. Then I decided to make the dimple just a tad larger. Deleted the original vector boundary and created a new one for the larger dimple. Now I have them same jaggy edge around it. :cry:

larger dimple.
Did you give the dimples more z-height to account for the dimples intersecting with the virtual surface of the hearts?

Walt,

In your component tree I don't see a zero plane, tried adding one and see if that helps. You'll also need to specify the modeling z height.

Thanks. Totally lost. The bottom of my hearts are at .9963 according to the preview, so I want to start the dimples from there and go down roughly 1/4". My piece is/will be 1-1/2" thick. The entire project except for the dimples is using the moulding toolpath. Starting at Z 0 at the top of the piece for the hearts, component settings give me options for +/- 3/4" so not sure how to tell it to start at - 1" give or take since it won't go there. :(

Walt,

Set the location of the Zero plane under Material Setup on the toolpath tab. And make sure to use a boundary vector around the domes.

Walt,

Is this what you're trying to do? Sorry I don't have the heart moulding, but I did a circle moulding toolpath.

John, thanks. I have set the zero plane at 0.9936 over on the toolpath side under Material Setup. That should be the bottom/deepest part of the hearts. I have also tried selecting just the model and Model Boundary, as well as the model along with the boundary vector and Selected Vector under the finishing toolpath. Nothing makes any difference, I still get the jaggy outer cut around the dimples as shown above in the first set of images. :cry:

And yes, your circle with dimple looks like what I am trying to get to.

I tried changing some of those modeling settings but have no idea what they are actually doing. :( When I resized the model the number in the Shape Height changed. That makes sense since when the dome/dish is made larger/wider it would also be deeper. Not sure what the Base Height setting does as it doesn't appear to make any difference. Reading the help file, again and again, didn't help any. And don't understand why I can only go plus or minus .75"

Walt, adjust "Gap above model" until the "Modeling Z plane" reads .9936

John, I did that. See image 2 posts above ^ :)

I think I'm onto something now though, but not sure what. I played around with the model Shape and Base height settings some more and got to where I can get a nice looking dimple without the deep jaggy ring around them. Settings attached. However they don't make sense to me still, it was all trial and error. The Shape Height is set to .2002 how ever the preview shows it only cutting down .176. If I make the Base Height anything more than -0.6 (such as -0.65) I start to get the jaggy outer ring. Still not putting it all together. :(

Walt, change the component mode to subtract not merge
