Opis

To makro wysyła aktualnie zaznaczony obiekt (siatkę, kształt lub korpus) na stronę PCBWay, aby uzyskać natychmiastową wycenę wykonania metodą frezowania CNC, cięcia laserowego lub druku 3D. Po przesłaniu obiektu otwarta zostanie strona PCBWay, na której użytkownik może dostosować szczegóły i opcje realizacji.

Uwaga: Obiekty oparte o siatkę mogą być wytwarzane tylko przez druk 3D. Dla frezowania lub cięcia laserowego CNC, potrzebne są obiekty oparte o kształt.

Użycie

1. Otwórz lub utwórz dokument FreeCAD zawierający obiekt, który chcesz wykonać za pomocą PCBWay.
2. Zaznacz obiekt do produkcji. Jeśli żaden obiekt nie zostanie zaznaczony, ale na ekranie widoczny jest tylko jeden obiekt, to właśnie on zostanie przesłany.
3. Otwórz Menadżer makr z menu Makro → Makra....
4. Wybierz makro PCBWay z listy.
5. Kliknij Wykonaj.
6. Przy kolejnych użyciach makro PCBWay będzie dostępne w menu Makro → Ostatnie makra.
7. Twój obiekt zostanie spakowany w formacie STEP (dla kształtów) lub OBJ (dla siatek) i przesłany do PCBWay. Następnie otworzy się okno przeglądarki, w którym będzie można uzupełnić szczegóły i złożyć zamówienie na wykonanie modelu.
