Fill-in a semi-circular rectangle


Re: For Sketchup 2015

Using the follow-me tool, I created a groove following a semi-circular curve. The groove was created with one exception; one side of the groove, although completely bounded by a curved rectangular plane, was left open. In other words no surface wall was created. The opposite side was filled in as expected. Although tedious, it is possible to individually select each segment of the overall curved rectangle; however, I’ve found no way to fill in the bounded surface. Does anyone have a suggestion?

Thanks, Jay


I can’t follow your description. How about uploading the SKP file so we can see it and help you out?

Please also complete your profile with useful information about the SketchUp version, operating system, and your graphics card.


I can upload a screen shot that illustrates the problem.


The SKP file would help more. With what little information you’ve provided, the best guess is that you are working at a small size. Try scaling up or using the Dave Method.


The groove was 0.25"x 0.25", which doesn’t appear to fall into the “small-size” category.


It’s the length of the short segments that form the arc that is the issue.


The shortest segment appears to be a minimum of 0.05"


If I select all segments, is there a function that will fill in the bounded rectangle?


There’s no native way to do it. You can trace edges with the Line tool to fill in coplanar loops of edges but if they weren’t formed during the Follow Me operation, it’s unlikely they’ll fill in. That’s why I recommended scaling up.


As mentioned, the opposite wall filled in correctly; given that it’s the same geometry I don’t see how scaling is the issue.


Ok. I’ll defer to you since I’m not able to see your SketchUp file.


Thanks for your effort and suggestions. :smiley:


If you won’t fill in your profile and you won’t attach the model and you won’t try suggestions, then what is the point of posting your question. All we can do is guess and be told our suggestions are wrong.


Solved the issue. Have a nice day :slightly_smiling_face:


Even ticked your own post as the solution.
I know who I’ll be ignoring from now on.


I laid out a well defined problem. The only solution presented (re-scaling) would have required starting over, as opposed to solving the existing problem - simply filling in the curved, bounded rectangle. Would have though this would have be a simple problem for a “Sage” to solve; unfortunately, my expectations exceeded performance. If this is an example of the expertise I can expect on this site - IT WON’T BE MISSED!

P.S. Ticked my own post to formerly indicate to the site that the issue was resolved, and no one else need spend their time providing a practical solution to a problem that was resolved. Have a nice day.


No, you did not!

The devil is in the details, and you failed to provide sufficient details for anyone to be certain they were addressing your problem. Instead you rejected attempts to help based on the partial info and posted contrary opinions such as “doesn’t appear to fall into the small-size category”, “the shortest segment appears to be a minimum of 0.05”, and “I don’t see how scaling is the issue” as if you know more than the experts. Despite requests you failed to provide an example skp fle but offered no explanation of why, choosing to argue instead. To make a poor analogy, it’s like saying “my algorithm failed to calculate an accurate value for pi” and rejecting suggestions from computer experts about possible causes but refusing to provide your code. The experts are not to blame!


Well it was probably just embarrassing to have had such an insurmountable problem solved so easily.
