So I found out today that when a circle is created, it is created with segments.
Instead of the initial creation of a “smooth circle”, it is in segments.
In other versions of sketchup there seems to a process to create or change a circle to have smooth edges. I can’t find out how to create a circle with smooth edges or change it once it is created.
I can right click on the object and choose smooth edges, but it doesn’t do anything.
How do I create/change a circle with smooth edges.
I was also thinking why anything but smooth edges would be the default for a circle.
Is there a property for circles that can be set to create it with smooth circles.
In all versions of sketchup all arcs and circles are made of segments, there are no curves in sketchup.
The default for a circle is 24, if you want more select the tool then before drawing type 48 and hit enter, then draw the circle and it will have 48 segments. Or after drawing a circle before changing tools type 96s and hit enter and it will have 96 segments. You can also select the circle, just the circle not the face, and change the segments in Entity info.
Do not make more segements than you need or you will quickly bloat your model.
Using a number that is divisible by twelve is the best way to go as it helps keep the cardinal points where you want them.
thanks. I redrew it as a circle. I have no idea how the original circle became just segments.
But anyway, it has smoother edges now.
I’ve tried to create a slot in the circle I’ve created. Worked on it for more than hour and
can’t make it work on the circle. At some point I did get it done on the object that was a segment.
See image circle 3.
I use the rectangle tool and then push it through the entire object. It just isn’t working now on the circle.
I can get a rectangle on the face. But I can’t get it positioned right. And then when I try to push it
through the object, all sorts of crazy things happen. Not sure how to describe it.
I’ve worked through the sketchup for web fundamentals class, but it isn’t helping at all for this issue.
How do I draw a rectangle on the circle. Need it positioned at a specific length from the edge with specific width. After drawing it, need to push it out of object so the slot is created.
Once it is pushed out of object, how do I select all the rectangle and then delete it.
Looks like you’re modeling a throat plate for a bandsaw or a scrollsaw.
To locate the position for the slot you can place some guidelines in the right location to identify the edges of the slot. Draw the edges on the top face a use Push/Pull to push down the face inside. It’ll want to stop at the step on the underside. But you can push again on the face to remove the rest of it.
What is your intent for the model once you have it completed? How many segments did you use for the circle?
Thanks. Got that done. Printing it soon. Will have to work out a few more details for a good fit.
It is for a bandsaw. I have one that is not that common.
Used 99 segments. I think I saw somewhere that was the limit.
One thing I noticed on the video is that you pushed the two layers separately and removed them.
Why does the first layer that is pushed delete automatically and the second one have to be deleted?
Also, why did you lines instead of a rectangle. I was using a rectangle.
When the lines are drawn, is it required to start the line off of the object.
I originally started on the object, but wasn’t quite working.
Suggestion when modeling for 3D printing at the end.
99 isn’t the limit for circles but it does depend on the size. I would suggest that you use a multiple of 12 segments for most modeling. It makes the modeling process easier when you need to start making edits. (Divisible by 2,3,4, and 6.) Also make sure you always drag out the radius of circles on axis.
No, it isn’t two layers. As I wrote, Push/Pull will stop when it gets to the step. That’s because it’s hitting some intervening geometry. It does remove the face there so you have to erase the edges for the outer part of the slot. Then you can continue pushing the remaining face through.
If you were using Sketchup Go or Pro there would be some other ways to create this that would be easier and faster but for free …
Either way works. A rectangle would include one more edge to erase but not a bit deal.
No. I did that to avoid potential inferencing to end points on the edge of the circle. I could have zoomed in closer and skipped extending the edges but I was trying to keep the GIF run time shorter so it wouldn’t make too large of a file.
You probably need to zoom in a bit to make sure the end of the edge you are drawing is on the edge of the circle.
When modeling for 3D printing I set the units to meters but think in millimeters. As an example, here’s a model I did a while back and printed recently. You can see that the main part of the connecting rodd is models as 60 meters long.
Here’s the 3D printed object with the pen for scale. The main part is 60mm long.
The nuts and boolts screw together without any problem.
Modeling this way gets around issues with tiny faces that can occur if you are modeling at real world dimensions. The threads on the nuts and bolts screw together perfectly.
These were done the same way. Modeled as if millimeters were meters.
I’ve found that 96 sides is plenty for a smooth circle for most things. Often 48 is fine, too.
