Popis
Toto makro vytváří kružnici opsanou 3 vybraným bodům na kolmicích nebo ve 3D zvoleném prostoru. Body mohou být objekty jako jsou krychle, válce,..., potom souřadnicemi budou středy vybraných tvarů.
Circle built on 3 selected points
Použití
Vyberte 3 body nebo tvary ve 3D pohledu a spusťte makro.
Je-li tvarem přímka, souřadnicí bude střed přímky.
Volby
Mód :
Defaut(přednastavený) :
- Defaultní mód vytváří kružnici podle 3 bodů nebo tvarů ve 3D prostoru.
- Pořadí vybíraných bodů u tvarů ovlivňuje úhly odklonu OS a zpětně odklon kružnice. V případě potřeby se lze vrátit a změnit pořadí výběru tvarů.
- Souřadnice X, Y, Z s hodnotou 0 nebo zarovnání, které neumožňuje výpočet, může vrátit chybu dělení nulou se zprávou Tyto tři body jsou vyrovnány
Vue Face :
- Vytváří kružnici v nárysu vybraného tvaru, 1, 2 or 3
Vue Dessus :
- Vytváří kružnici v půdorysu vybraného tvaru, 1, 2 or 3
Vue Droite :
- Vytváří kružnici v bokorysu vybraného tvaru, 1, 2 or 3
Alignement sur :
Forme 1, 2, 3
- Tvary podle jejich výběru.
Afficher le centre :
- Je-li políčko zakliknuto, bude vytvořen i středový bod kružnice
Associer les couleurs
- Je-li políčko zakliknuto, kružnice přebere barvu aktuálního pohledu,
- Pohled shora (X,Y) = Modrá(osa Z)
- Pohled zepředu (Z,X) = Zelená(osa Y)
- Pohled zleva (Z,Y) = Červená(osa X)
-
Kružnice na 3 tvarech (pohled zepředu),
-
na kolmicích na vybraném tvaru (pohled zprava)
-
-
Tři nezávislé kolmé kružnice na vybraném tvaru.

# Cercle sur 3 points.py
# create a circle from 3 points selected
# combination of the two programs 'create a circle from 3 points selected'
# with as options (orthogonal) circle can be built on a choice plans
# to coordinate one of the three selected choice shapes
# mode by default, creates the circle in 3D space
# the options create the circle of orthogonal way on the map and view the choice
# with the creation of a central color related to the axes Y/N Y/N

# read the note in pdf, on the order of selection points,
