arc, round error
hi,
i have an arc in dwg file. the arc is given by center, radius and angle. i get some round errors during transformations (opendwg and/or my own) and one of arc ends is displaced. is there possibility to keep in the database arc given by three points? (start, end, some point on the arc)
best regards,
michał Śliwka
oddbarc entity stores center, normal, radius, start&end angles.
the way for storing an arc as 3 points exists - you can implement a custom entity for it. but it will not be recognized by autocad as arc - autocad will see it as proxy entity.
