Good day.

Quick question...why is it that sometimes I cannot find the center of a circle?

When I have a line command selected some circles have the indicators for the center and sides and some circle do not have this?

Thank you!

Hi Matadem,

There could be different possible reasons, it's hard to know which particular issue you're running into without being able to analyze it.

Please post a .3dm model file with an example circle in it and that will help me to answer your question.

Attached a sample.

Tnx.

Why your circles are in the empty space without links of the grids ?

Move them to the center grid and you will see their centers! :)

if you don't want move them use the Helpers lines !

Hi Matadem, the circle shape that doesn't get a center snap is not an exact circle, it's only pretty close to being a circle.

How was it created, was it an import from a PDF file possibly?

You can replace it with an exact circle by selecting it, then run Draw curve > Circles > "3 pts" and place 3 points snapped on to it then delete.

Yes it was from a pdf import :/

Hi Matadem, there isn't any method in PDF files to have exact circles. It only has either lines or general Bezier curves.

So something that looks like a circle in a PDF is not precisely an actual circle, it's just a generic spline curve that is shaped similar to a circle.

The one in your case here deviates from an exact circle by around 0.003 units. It's a little too much deviation for MoI to consider it a circle.

Hi Matadem, if the app that generated the PDF file is able to have true circles in it, then you might try using SVG or DXF format if possible, rather than PDF.

Both SVG and DXF have a way to store precise circles in them which PDF does not.

But even for this object, selecting - Bounding box center makes it work.
