# Rotate to Align question (answered)

## Recommended Posts

I have to believe that I have been missing some basic Chief action all these years, so finally I'm going to embarass myself to ask...
How does one align an entire cad shape/polyline, not just a selected edge of that shape?

Probably an easier way ... I'll get the angle of the line, then rotate the shape to match.

And then try to remember that a negative angle rotation is clockwise and  positive is counter-clockwise...which is also counter-intuitive!

I've wondered the same thing as the OP many times (including a few minutes ago). I hope a solution shows up.

Thanks Eric...   that seems primitive when we have the align/make parallel tool,  but it certainly works!

If you use 'absolute' then you won't have to remember pos./neg. BUT it still seems such a primitive way of doing it, when it should just be a matter of a couple clicks.

Yeah, you still do. If I have an irregular pie shaped lot that I'd like to rotate an absolute angle, I'll have to know if it's a positive angle or a negative angle when entering the value using the transform / replicate tool.

Example, the lot I'm currently working with has one side that is 1.27964 degrees off of north. I'd like that side of the lot aligned with my building. So to rotate it, I'll need (in this case) a negative rotation of 1.27964. A positive rotation of that amount would make it 2.55928 degrees off.

What we need is a make parallel tool that function like the point-to-point move tool. Select objects to make parallel, then select angle 'A' to make parallel with angle 'B'.

Double click on the Make Parallel/Perpendicular tool (or just click it a second time).

Easy! That's awesome Alaskan_Son! I knew I had seen that dialog box at some point in the past and I was challenged to try and figure it out. Thanks!!!

Double click on the Make Parallel/Perpendicular tool

I see that works for a single polyline only.. not multiples, correct?

Double click on the Make Parallel/Perpendicular tool﻿

Ha!...  great!  Thanks Michael.  Grrr... I did not see that in the Parallel/Perp tool description.  Now looking with more scrutiny I see at the very end there's a link to another page describing that function.  Seems to me that info should be on the same page or mentioned earlier in the tool description.

Not sure what you mean, but if you select multiple polylines and try to Make Parallel/Perpendicular, you won't get the option they will automatically Rotate Entire Polyline because there is no Selected Edge to work with.

That's what I meant. I typically have a fair bit of my site plan drawn while the lot perimeter is positioned relative to its north bearing. Then I'll rotate the group of objects for building placement. Still, good to have that tip about double-clicking the make parallel tool!

Rob, if you select the edge of your lot that you want to align with your building, and in the transform/replicate dbx enter 1.27964 as an absolute angle it should work.  If you entered as a relative angle, then you're correct it'll either add or deduct that angle from it's current position.

Yup, you're correct. I'm using the relative angle as I'm rotating a mostly completed site plan which is multiple objects.

Wait...  you need to use the absolute angle of the building wall... which I think is actually 358.72036 based on what you're saying.

There's another tool you guys can be using as well...

The angular dimension tool.  This will allow you to reference 2 specific edges and move as many objects as you like.

I don't think I saw it mentioned, but beside the double click method mentioned by Michael earlier, you can shift select your polyline and then use the make parallel/parallel tool

The problem with this method is that it uses the bounding box of the polyline and not a specific edge.

Bounding box being plan north, useful to know for anyone finding this, easy to make a 90 degree corner perpendicular to a reference in this way.

Click the edge of the polyline you want to make parallel and then dble. click the make parallel tool and select "rotate entire polyline".
