TechDraw RadiusDimension/ru

Описание
The TechDraw RadiusDimension tool adds a radius dimension to a View. The dimension may be applied to any edge which is a circle or circular arc.



Применение

 * 1) Select a circle or circular arc. The geometry may be selected in the 3D view or in the drawing. Note some arcs which appear to be circular are actually ellipses or B-splines. You cannot make a radius dimension in these cases.
 * 2) If you have selected geometry in the 3D view: add the correct TechDraw View to the selection by selecting it in the Tree view.
 * 3) There are several ways to invoke the tool:
 * 4) * Press the button.
 * 5) * Select the option from the menu.
 * 6) A dimension is added to the View.
 * 7) The dimension may be dragged to the desired position.
 * 8) If needed, add tolerances as described on this page.
