Rotating a line shape about a point.
Posted on 2011-09-28
I'm trying to rotate a line shape (created with the Shapes.AddLine method) about a point.
I've found an example authored by Chip Pearson - a clock - that does this nicely. It uses the following code to move the second hand:
However, when I try to run this code in Excel 2010, it returns the following error message:
"The specified value is out of range"
(Variables NewX = 296 and NewY = 107)
I've attached the original source file. Can you assist me in getting this to work on the newer version of Excel? Clock.xls
I've found an example authored by Chip Pearson - a clock - that does this nicely. It uses the following code to move the second hand:
Private Sub SetSecondHand(Seconds As Single)
Dim Theta As Single ' clockwise angle from vertical
Dim NewX As Single
Dim NewY As Single
Dim LS as Shape
Theta = (Seconds / 60) * TwoPI
NewX = cCenterX + (cLenSecond * Sin(Theta))
NewY = cCenterY - (cLenSecond * Cos(Theta))
LS.Nodes.SetPosition 2, NewX, NewY
However, when I try to run this code in Excel 2010, it returns the following error message:
"The specified value is out of range"
(Variables NewX = 296 and NewY = 107)

A little more investigation - the shape Chip created (in an older version of Excel) with the Shape.AddLine method has no nodes in the newer versions of Excel. LS.Nodes.Count yields 0. If I create a free-form shape, it has a positive node count. Apparently the lines created with Shape.AddLine are different and node-less.
The problem is that from excel 2007 the nodes property is no longer used and instead the rotation property is promoted.
let me see if i can come up with a solution...

I've worked with the rotation property - but it rotates about the center point of the line. I want to rotate the line about the end point.
I think the nodes property is still accessible. If you draw a free-form line and check for nodes in the immediate window, it returns the correct answer - but not for a autoshape.

dsimcox, have you tried the updated version of the clock.xls file ?
it uses polylines instead of lines. With polylines (which do have node objects accessible) the clock lines indeed can be pointed 'in the right direction' using macro code.
The version that I uploaded works at my workplace, using excel 2007.
Can you verify that it also works at your location ?

I'd like to try the newer version of clocks.xls but I don't know where to find it. Can you post a link please?
it's in my post 36813503 of september 29th @ 10.28 AM
you can click on the underlined text clock.xls

I was able to use this example to get my code working. Thanks for making the updates to Chip's code. It helped a lot!
