why isnt this working for me.. when i try to angle the half moon the other side is swinging out. the flat side isnt staying in the same plane.. the top of the arc and the other side are both moving outward
Try this: > Create a circle with the circle tool (obviously😋) having a 3/8" radius. > Use the push/pull tool to extrude the circle into a cylinder. If you know the desired dimensions already, extrude to match the length of the long side of the 45 degree cut. > Don't group anything or make a component yet. > Rotate the cylinder (or whatever you gotta do) so that the bottom midpoint of one of its faces coincides with the origin. > Nearby, create a rectangle having the same length as your cylinder, and with a height about double the cylinder's diameter - so 1.5 or 2 inches should do. > Make this long rectangle a group of its own. > This rectangle will be a "cutting face". Rotate it so it is oriented upright along the blue axis, then position it so that it bisects your cylinder down the length. > Zoom out so you can easily drag the mouse to encompass both objects. Once everything is highlighted blue, hold down the shift key and mouse-click the cutting face to deselect it. > With your cylinder selected, right-click, and select intersect faces/with model. > Click the mouse somewhere away from any object to deselect everything. > On a broadside of the newly bisected cylinder, double-click about the middle of the face so that half of the cylinder (edges, faces) highlights blue. > With this half-cylinder selected, create a new component out of it. > Next, rotate your cutting face 45 degrees along the blue axis, then move it to coincide with the midpoint of the half circle face at the end of your cylinder. > Double click your new component so that it can be edited, double click it again to highlight the whole thing blue, and once again intersect faces with model. > Move the cutting face away to isolate the component, then delete the "cut-offs" (the extra edges&faces created when you intersected). > Rotate as necessary to repeat at the other end of the trim. > Congratulate yourself on a job well done.. 😉
Has anyone ever told you that you sound exactly like Matthew McConaughey? When watching this video, I couldn't help but think that Matthew himself was giving this tutorial. lol!
Tommy Tompkins I just watched this for the first time and was thinking man this guy sounds just like Matthew McConaughey , I wonder if anyone else commented about that??!
This is not the best technique, as it introduces unnecessary lines that you can see if you view hidden geometry. There are lines in the moulding that are no longer parallel, as they were before you rotated and scaled the face. This could introduce problems down the line if you need to do more scaling, etc. with that geometry. It would be better to group the moulding and then create a rectangle *outside* the group, rotate it 45 degrees and then position it so that it "cuts" completely through the moulding. Then open the group, select everything, right click and choose "intersect faces -> with model". Now you can erase the part of the moulding that you just "cut off", close the group, and delete the rectangle you made to cut it with. You'll probably notice that the cut left an empty face letting you see into the interior of the moulding. Just open the group and draw a line along any edge to close that face. That's one way; there are several others, all avoiding the problems with rotating and scaling that face.
Thank you mr. Hart, your tutorials are really helping me out while studying sketchup at home.
Very helpful! Thank you so much.

Ha! Thanks... actually another guy actually told me that a couple months ago. Maybe I could get a gig as a voiceover actor!

This worked perfectly!
