Автоповорот точек

[karpushkinajul]

Здравствуйте, нужна Ваша помощь! Работаю в ArcGis 10 и потребовался скрипт который автоматически поворачивает точку вдоль линии!!! На версию 9 такой скриптик есть но в 10 он не работает!!!! Помогите пожалуйста!!!! Буду рада любой помощи!!!! Может ссылки посоветуете!!! СПАСИБО!!!!

[Максим Дубинин]

поворачивает точку говорите...

[gimran]

Попытаюсь перевести: топикстартер хочет "подтягивания" точек к заданной линии.

[karpushkinajul]

Вот труба с газом (линия) а вот задвижка (точка) на трубе... Так вот задвижка должна автоматически повернуться относительно трубы. Есть такой скрипт в 9 он через макрос подключается.... а вот в 10 не знаю что и делать и с чего начать и куда приткуться!!! Поможете?

[gimran]

Может лучше опубликуете скрипт под 9ку? Проще готовое модифицировать, чем форумчанам писать заново.

[karpushkinajul]

Объясню ситуацию. Я на работе новичок и только я работаю с 10. у всех стоит 9. мне скинули программки скрипты но они в 10 не работаю! Вот скидываю инструкцию к этому скрипту:

Спойлер

This script will select the first layer in the TOC, if it is a polyline and has at least one line/record selected, it will add two fields called AriAngle (Arithmetic Rotation aka Polar) and GeoAngle (Geographic Rotation aka North Azimuth) and populate the fields with angles for each selected line/record based upon its from to direction.

If you would like to make improvements to the script, feel free to do so and send me the new script
Created in ArcGIS 8.3, not tested in 9.x

Portion of script based upon ESRI ILINE Example
Portion of script based upon DOUGLAS R. GUESS - LANCASTER COUNTY ASSESSOR/REGISTER OF DEEDS OFFICE

NOTES:
A least one polyline must be selected
The script will only work if the polyline layer is the first layer on the TOC
To calculate the value of PI = 4 * Atn(1)
To convert Angles to Radians (Radians = Angle in Degrees * (PI/180))
To convert Radians to Angles (Angles in Degrees = Radians * (180/PI))

Calculated Angle Arithmetic Angle Geographic Angle
90 90 0
| | |
| | |
180 | | |
-180 ----------- 0 180 ---------- 0 270 ----------- 90
| | |
| | |
| | |
-90 270 180

This script will choose the first layer in the TOC and makes sure that it is a polyline
This script will make sure at least on polyline/record is selected
You do not have to be in edit mode for this script to work, just run the macro FindPolylineAngle

какая то чушь получилась...

[karpushkinajul]

я не знаю что мне делать, я уже запуталась

http://www.microsofttranslator.com/BV.a ... id%3D14234 вот ссылка на этот скрипт он на Vb а надо Python

[karpushkinajul]

нашла скрипт для 9 вот он

karpushkinajul, пож-та, используйте тег [spoiler] (сворачивающийся блок), не пугайте нас простынями текста

[Александр Мурый]

Если я правильно понял, вам нужен инструмент типа "Find polyline angle" под 10-ку, так? Поиск чего-то даёт, надо экспериментировать.

[karpushkinajul]

Александр Мурый, все верно!!!! НУЖЕН нструмент типа "Find polyline angle" под 10-ку)))) как быть??? форумы все облазила.... может что-то упустила? Помогите пожалуйста!!!!!

[Александр Мурый]

А если попробовать сделать, как советуют здесь?

[karpushkinajul]

Александр Мурый, здравствуйте!!!! На выходных не было времени (извините), но сейчас я буду изучать и попробую, как советую вот там!!!! Спасибо за старания мне помочь)))) Может есть еще новости???
