**Perfect alignment constraints for all 3 corners of a fabricated triangle from bars.**

Problem:

Align final (3rd) corner bolt holes in diagonal bracing. (simplest method I have found)

Solution:

Also see attached.

1. Use "Align" constraint to constrain the holes in 3 bars. (2 constrains) This leaves the third set of holes as the problem.

Make sure that the 2 non-diagonal bars are constrained for proper angular relationship. (e.g. 90 degrees)

If you try to measure the distance between each of the remaining holes and input it for the

distance of the final "diagonal" piece hole, it WON'T work. (more than likely)

So, do this...

2. With first 2 bars constrained at their proper angular relationship, use the "measurement tool". Measure the diagonal distance

(open side of the triangle) and COPY the number that is automatically entered in the tool dialog. This should be the center-center

distance of the diagonal distance.

3. The final align will need the last hole spaced from it's counterpart on the other end of the 3rd bar. At this point there's only one

hole in the bar.To do this, draw a line perpendicular to the bar through the center of the hole. Offset that line to the other end

of the bar for the location of the second and final hole. In the dialog for offset distance, PASTE the number you copied in step 2.

That is the distance for the final hole. Don't forget, this could be either the C-C or it could be the inside measurement between

the two holes, depending on how you measured. If it isn't C-C, then ADD (Hole1Diameter + Hole2Diameter / 2) to the pasted

number.

4. Mark the final hole and drill it.

5. Now align the remaining two holes, closing the triangle. (if it starts flopping around, just anchor one of the non-diagonal bars)

DONE

This isn't the only method to accomplish the above task. So use whatever works for you in your own area of endeavor.

Give this one a try. It really is easy and it works.
