chasing the division points

Anonymous — Sat, 15 Sep 2012 10:00:09 GMT

Here is a new one I never noticed before. I divided a circle into ten parts using the Control Box> Special Snap Points> Divisions. At this point I want to mark the divisions with the Point tool. The first and second points are placed fine, but when I try to place the third point the divisions have been moved. Is this normal? How can I lock the divisions in place?

Thank you

Also bear in mind this only applies to circles not arcs or lines.

zoltar:

It looks like ArchiCAD uses the point closest to a 90˚ point on the circle where the cursor contacts the circle as the start point for the divisions. So touching the circle in the upper quarter will place the start point at the top, touching it near the side will put the start point at the right or left.

One method is to touch the circle near the top to get the divisions correctly, then try to approach the circle radially at the division point to place the Hotspot, but this is not easy. Another method is to place two hotspots near the top, then use the Multiply command to place the other Hotspots.

Divisions are calculated from an endpoint (the nearest to the cursor) that a circle don't have, being a close curve. The nearest quadrant point is then used, as David stated. If you have difficults, try using two semicicles, divided in 5 parts.
