As Gully pointed out above, the behavior is erratic. Sometimes one or more of the holes cuts the bottom face, other times none of them do. Sometimes redrawing an edge cause the hole to be “healed”, other times it does not. It seems to be sensitive to the details of the geometry. In my tests, triple-click did not reliably eliminate the issue.
Geo, did you try a bunch of variations on size of the holes and slope of the cutting plane? Also, if one selects the cutting plane (not the cylinder and holes) and does intersect with model, triple click is irrelevant. In the tutorial you need that action because you are selecting the cylinder for intersect with model, and you must be sure you got all of it.
A key step in your video is doing a second intersect-with. This causes SketchUp to revisit the intersections, which may cause it to notice holes where a single intersect did not. However, as pointed out above, the failure seems to be sensitive to exact positioning of everything. You may have gotten lucky the way Geo did.
Thank you 1invisiblegod. I’ll have to watch that several times to catch everything you did. It was a little different to the process I used. I wasn’t quite sure why you created the box in order to create the angled face that you used to cut through the disk? The way you formed the oval holes was clever and much easier than the way I did it but I guess those are short cut techniques you pick up as you become more expert. I’ll try this and report back on my success or failure. Thank you again.
Doing the intersect faces with model the second time resulted in being able to select and delete the oval shapes that were not individually selectable before so thank you for that. How did you do that soften edges where you selected with the red and green lines? You went up to the menu for something but it was out of view so I couldn’t follow you.
Hello and it is a very cool way to get it done (His video)…the tool is Round Corners but it does have 2 more features. Sharp corners and Bevels. It is great for table legs and other lathed objects that have a curve in them. With a straight edge you can offset the edge to both sides of it with move-copy, and then just move the original to one side or the other. This would give you a beveled edge but gets weird with a curve involved. It is free in extension warehouse but requires LibFredo 6 (library) to be installed first. Then it will allow other Fredo6 tools to function. They are a great time saver but if you are not comfortable with what SU already offers. You should wait till you know what they can do, before adding more frustration to the mix. I thought they would help me starting out and only added more unknowns in stead of helping me solve anything or learn faster…Peace…
