Poly to Arc

Hi everyone,

Do you know if there’s a function in TBC that can convert a series of small segments, which form an approximate arc, into a real arc?

When I import a DWG into TBC, it often gets broken down into small line segments. I’d like to find a way to convert these into actual arcs.

Thanks in advance!

Hi Andrea,

I don´t know a function or macro inside TBC to do that, however, a workaround would be i.e.:

1- Select all line segments, right mouse key and "Join Lines" --> You get a Linestring

2- Select the Linestring, right mouse key and "Edit"

3- Then you can change all segments from "Straight" to "Smooth curve" if more than 2 segments, or to "Best fit arc" if only 2 segments (3 points defining the arc)

I experience the same but from TBC to DWG, not sure if it´s a bug or any setting is needed to do before exporting to DWG to keep the arcs and splines as they are in TBC.

Regards,

Fernando

Hi Fernando,

Do you think it’s possible to turn all these steps into a macro?

Thanks

Hi Andrea,

sure, it would be possible via a macro, not sure if RPS or ANZ offer such a function already, but it could be done via a macro.
