Hiding geometry in follow me

Sometimes when using the fillow me tool, it works but the geometry becomes visible. I’ve just made a disc shape with a rolled edge, setting sides at 150, after applying the follow me tool all the geometry is visible, next it looks like I’ve got a big job using the Eraser Tool - shift to hide the lines (thousands). Is there any way to toggle a command and hide or group and hide these lines?

Select the geometry, right click and select soften/smooth edges then adjust to suit.

Thanks, so obvious. Another question, I’ve attached two images, intersect old as ou can see I’ve intersected two parts of the work successfully and deleted what I didnt want (they are two intersecting discs - Intersect which is the new one I began again, increased sides to 150 and now I’m having problems manouvering the two discs together to perfectly alighn, they keep on snapping out of alignment, is thee a snap option I can turn off? this is a very high magnification but I need to vreate a smooth intersect between the two disc elements. Eve if I get a clean registration between them deleting the parts of the curves I dont need looks like will become a nightmare. Any suggestions.

You don’t say how large the parts involved are, but I suspect you are encountering problems with SketchUp’s nearby vertices tolerance. The issues with small edges and faces disappearing are well-documented. Less well known is that SketchUp may snap to an unexpected point when a line passes too close to another existing line. In any case, you should try scaling the model up by 100 (or if necessary even 1000), doing the alignment, and then scaling back down.

Coming from that likely explanation, why are you using 150 segments? A value divisible by 4 will give you fewer issues because it puts vertices in cardinal orientations. But also, 150 is a larger number than needed for visual smoothness. If you are targeting 3D printing, it is even more likely that the whole model is too small for SketchUp to manipulate cleanly without temporarily scaling it up.

Thanks, the scale of the model is 1:1 the discs are 1 meter in diameter in Sketchup, I used a high number of sides so that I could create a smoother profile on the disk. I suspected that by doing this I’ve created a problem. I do intend 3D printing the work at some time in future - I also run these images thru Layout onto an AO page to generate a detailed PDF which I can print large scale after cleaning up in Photoshop. Shame about the snapping its driving me crazy. From what your saying, you reccomend maintain scale but reduce detail via reducing the number of sides?.

I recommend enlarging the model while drawing, especially when intersecting or doing follow me. You can temporarily enlarge it by measuring between two points with the tape measure and then immediately typing a new size for the distance between those points (SketchUp will ask you to confirm that you want to resize the whole model). When you have finished drawing, rescale the model back to its real size by again measuring and entering a real distance. In other words, the enlargement is needed only as a workaround while you are drawing small details that might encounter SketchUp’s nearby vertex cleanup; once the drawing is done, the details will be ok at their real size.

Regarding the number of sides, it comes down to a matter of use of the model. Far fewer than 150 will look just fine at almost any reasonable viewing scale provided you soften/smooth the edges. For very fine 3D printing, though, you need to choose a number of sides that will provide a satisfactory print given the resolution of your printer.

Hi there, slight thread hjack, but can I ask how you made that? The process you followed before the smooth/soften edges? Thanks.
