How can I make a rectangle 9/10" across? Rounding problem.

Charlie__V

remotely relevant......but....land surveyors routinely use "tenths".
IE: N52° 43' 48" E 89.1'
The "length" (ft) is routinely expressed as in above example.(89.1')

They might use tenths of feet but they don't express them as fractions.

As I wrote, tenths are very common on British rulers. Possibly you are an American, and things are different there? When I was using fractions, I typed in 9/10" and I did NOT get a rectangle of the correct length. When I measured it with the ruler tool, it was the wrong length. Wait! I just checked that, and it seems you (Jeff) were right! What it said and what it did were two different things!

Anyway, today's problem is that I have followed several how-to-draw-a-sphere tutorials to the letter, and SketchUp refuses to do anything of the kind. Instead, it is creating many different bizarre and apparently random shapes, and sometimes causes the shape to disappear entirely. But that's another story for another day...

As for your sphere, how big is it? How many segments per circle? I'll bet you're running into the tiny face issue.

You really ought to upload the SKP file so we can see what you're seeing.

I've spent a lot of my life in England and have seen rulers with tenths, but not often.

To add to what Dave has said, I bet your two problems with the sphere are working too small and trying to drag the follow me tool.

Select the path first then select the follow me tool and click the profile.

Hi Rich, hi folks.

Using 0.04" as equal to 1 mm is slightly inaccurate since it implies a division by 25.

To convert millimeters to inch you need to divide by 25.4.

1 mm is then 0,03937007874016 inches (approx.).

Just ideas

On spheres, I just had another go and got some weird results, but I did manage to get a sphere by using a different method from the one I used to use. I was using SketchUp 8 (I think, or 7) before which was a bit different (for example it had the 'follow me' tool as a button instead of a menu item, which I preferred - I've looked hard for a way to create a button for it in SketchUp Make, but perhaps that's only now in the 'pro' version.)

By making the guide circle a group, and then positioning the thing to be made 3D very precisely above its centre and not touching it at all, and then exploding the group, I managed to create a sphere. A warning message flashed up for an instant, but I couldn't read it before it disappeared.

I then went into my current project to repeat the feat. No luck! The results seem quite random. Sometimes it disappears, sometimes it becomes a 2D object with bits missing, and other times it becomes a bizarre 3D shape that defies description, but which involves lots of apparently random missing bits and even floating pieces.

I never had this much trouble with spheres in SketchUp 7 (or was it 8? - it might have been 5 or 6).
