I import arcs from a dwg file and I need to create a point in the middle of these arcs.
How I can do?
Thanks

Hi Mica,
You can use the Snipper to create the middle point of a curve including arc.
Firstly, calculate the half length of the arc. LengthCalculator and ExpressionEvaluator can be used, for example. And then use the Snipper with these settings:
Snipping Mode: Distance (Value)
Starting Location: <the half length>
Ending Location: <the half length>
Hope this helps.

Hi,
The easiest way omi.
First arcs must have some ID
1) use a boundingboxreplacer on the arcs. Set it to orientedboundingbox.
Replace with its centerpoint. Extract coordinates.
2)
Paralell to this: stroke the arc and extract 1st and last coordinate.
Extract coordinates.
3) Merge 1 and 2 by ID.
Use creator to midpoint of points found at 2)
Vertexcreate, set to replace.
Vertexcreate cordinates from step1) Set to add.
This should give u a line troug center of outerpoints of arc.
Extende by at least half of shortlength of boundingbox (this is a attribute of the boundingboxreplacer).
Intersect this line with the boundingbox.
You should end up with the midpoint of arc.
Oh, I've overlooked "Distance (Percentage)" mode. You don't need to calculate the lentgh.
Snipping Mode: Distance (Percentage)
Starting Location: 50
Ending Location: 50
