technical sketch - triangle

[Einav22238759joid]

Hello everyone.

I have been a graphic designer for a long time and know Illistrator pretty well (and beyond), but I've got something I just can't find a way to do!

I need to dray a rectangle by line length, meaning:

The base should be 85mm, one side 60mm and the other side 70mm.

and I can't figure out a way to do so!

Does anyone know a way to do such a thing?

There may be some scripts out there or one can be created to do it, but if you want to do one now, you can low-tech it and use some shapes to give you your end result. In my example, I drew a rectangle 85mm square (It could just as easily been a single line 85 mm in length, but the square is a quick thing to draw. I then drew two circles of 120mm diameter (to give a radius of 60) and one 140 mm (for the radius of 70). I selected the two circles and used the Pathfinder to Unite them (or Divide.. a bunch of them would do it) which created a point that can be snapped to to use as a guide to draw the triangle.

Einav,

There are (almost) always more than one way that Illy (job description Adobe Illustrator) can help us, and very helpful she is.

Another way is to (Smart Guides (still) being your friends):

1) Click with the Circle Tool and set W=H=85, then hold Ctrl/Cmd and press C then F then F again; now you have three circles on top of one another;

2) Click somewhere on the (topmost) circle, then insert 120 in the W box in the Transform panel, then ShiftClickDrag that circle sideways by its centre to snap to one of the side Anchor Points on the circle(s) beneath (Smart Guides say intersect when you are within snapping distance);

3) Repeat 2), only inserting 140 and ShiftClickDragging to the other side Anchor Point on the (original) circle beneath; now you have the three circles in position;

4) With the Pen Tool Click each of the side Anchor Points of the original circle, then the topmost intersection of the other two circles, then the first side Anchor Point again (Smart Guides say center, center, intersect, anchor, when you are within snapping distance); now you have the triangle with the base at the bottom.

I hope others will join in.

Hi Brad. Still no show there (there have been a few here.)?
