Bar Cutting Optimization????

Hello, can anyone help me please? I am trying to create a worksheet from Excel that will allow me to optimize bar cutting lengths for example. I will have metal bars of a standard length and will need to cut various different lengths from this. Once i imput my smaller cut lengths and quantities of each i want the worksheet to be able to work out how many total bars i need to order of standard length and if possible identify which smaller bits need to be cut ffom the bigger bits. It might seem a bit difficult to comprehend but anyone who has used a bar cutting optimizer will understand my query! If anyone has already set up such a worksheet i would be most grateful if they could either let me know how i can get it or how to create one. Thanks

Imagine a whole box of lengths of aluminium sections for making windows.

To make those windows I need to cut these lengths into smaller sizes.

I need to do this economically.

How can I use Excel to help me make this a reality.

Firstly you would take a big size out of it and then another size out of the offcut piece.

And then another size out of the offcut left over.

I need to know how many full stock lengths (6500) long it will take to cut all the pieces listed above.

Is it possible?

You need to take into account the quantity of each size and fit it all in together for the most optimal outcome.

See attached example of possible layout.


Seemingly super simple, but I can't figure it out.

Hi guys,

Looking for some help and would appreciate your help. I want to prevent people cutting/copy/pasting on a spreadsheet I have developed. A couple of users keep doing so which in turn knackers my formulas. There will be occasions where I will need to be able to use these functions for maintenance and updates. Ideally I would like have a private marcro which I can run to enable these features as and when needed.

I've been at this all morning and feel like I'm going round in circles. I've tried various bits of code (sourced via google etc) & have ended up with a whole manner of outcomes but not the one I want.

To summaraise what I am looking for is some vba code which will do the following Disable cut,copy and paste when sheet is opened Enable cut,copy and paste when closed Have a macro which when run will allow me to cut/copy paste so as to implement updates when necessary.
Can anyone help?

Thanks in advance

Hi everyone....this is my first post here ....and not my last I believe!

My question I believe is easily solvable for you cracks of excel.
I have a worksheet with a list of rows (item#, date, price, etc). In the last column of this list I can put an x for some of the items.

I created an example on a worksheet attached just for you to understand.
I apreciate all the help I can get.
Thank you so much.

I'm trying to separate bars inside a bar chart into separate groups. Adjust the gap applies to all bars. How will I be able to achieve what I need? Please help and thanks


I have looked over the forums for information on how to do this, and can not find anything. I have used conditional formatting to identify duplicates in my spreadsheet. I have a unique user ID, which combines the first and last name fields into one. However, in 10,000 there are a number of John Smiths, Joe Adams, etc. With smaller lists, we search manually, and then add a 1, 2, 3, etc to each duplicate to create a unique value for the User ID.

My question is:

Is there a way to check for duplicates, and then automatically add numbers to the duplicate values to make them unique? If so, how can this be done?

So that you will have this:

JohnSmith
JohnSmith2
JohnSmith3
JaneDoe
JaneDoe2
JohnAdams
JohnAdams2
JohnAdams3
JohnAdams4

I think I have done a good job in illustrating what I would like to be able to do, but if there is still something that is unclear, I will post whatever clarification is needed.

Thank you in advance for your help!!


Good afternoon,

Is there a way to enter a colon into a standard number to create a value that can be formatted into a 24 hour time value ?

eg a time is listed as 1345 with a general number format, and I want it returned as 13:45 witha custom format of hh:mm.

Other than creating a table and using a vlookup function, I am hoping there is a better way?

I added a print button to my userform

Code:

Private Sub btn1_Click()
UserForm1.PrintForm
End Sub


This prints out the userform as I would like, however it autoprints to the default printer and doesn't allow any printing options so I can't select to "print to one page". So as of now it is only printing out half my form and cutting off the rest.

Any suggestions?


Also, I cannot move the Pivot Table from the new Worksheet it is created in, to my existing Worksheet.

I am running Excel 2011 for Mac.

I have a Worksheet with a small amount of data, and when I click the Pivot Table button it automatically creates the Pivot Table in a new Worksheet. The Pivot Table data is fine, but I want it to display alongside the source data.
I've tried using the Move Pivot Table option and choosing to Create Pivot Table in Existing Worksheet and choosing a source cell alongside my current data, but nothing appears. Also, I checked in Edit menu and found that the Pivot Table appears to have not even been created/moved because there is no option to undo it.

Appreciate any help, let me know if you have any further questions.

Is there a way to use the new conditional formats (data bars, icon sets, etc) in PowerPoint? Basically, I'd like to create a table that shows icons based on data, like in Excel? I know I could paste a pre-made Excel table as a picture, but I'd like to avoid that if possible.

Thanks!


I have a pivot chart with a bunch of data series, and every time we
include/exclude one of the series to see how the chart changes, all the
colors change and we have to spend time re-identifying which series is
which, using the legend to check the colors.

Is there a way to "lock" the colors, so that the bars stay the same colors
regardless of whether other bars are included/excluded?

Thanks!

I have a couple of worksheets that have goal seek already performed on 20 target cells (for each worksheet). I did this manually, without a macro (since I'm absolutely horrible at all of this).

Now from what I can tell, I need a code to add to the worksheet module in order to make sure that the goal seek updates itself whenever I change a value in the formula of the target cell.

what IS that code?! I can't understand the codes some people have put up, so I have no idea what to do.

Target Cell: M21:M42
Changing Cells: N21: N42


Hi All,

I am trying to make excel automatically add a leading zero to values which are 5 digits long;

i.e. number input is 15185, then excel automatically changes it to 015185.

If I put a Customer Number Format of 0##### it works, however, a user could put any length of number into these cells, and if the number is less than 5 digits I don't want a leading zero.

Is there any way of writing a small macro to sort this out.

The numbers would be input into range B16:223.

Many thanks,


Andy


Okay, so I tried (for hours) to find a solution to this and have finally gotten frustrated to the point where i think asking here will be my best bet.


Basically I want to export data from excel worksheets to various places on a word document I had. I have created a word template as well as bookmarks for that template, as that seems to be the recommendation for performing such a task with excel.

My problem is ... Now what?

I basically have 1 constant worksheet that contains all my affiliates info (Name, Address etc), which i'd like to use to populate some bookmarks in my word template, and then i have another worksheet for the previous month, indicating sales etc for that affiliate. I intend on adding a new worksheet every month that i would use to create new invoices.

Furthermore, i'd really like to be able to update a new file (or perhaps a new page on the same file) for each company with the use of a button, similar to the one's you'd see in an access form.

Can anyone help? Let me know if you need me to clarify.

Thanks!

Hi Everybody,

First post on the forum, have only recently joined and im hoping that someone can help me before my head explodes!

I am trying to prepare a simple Material Quantity List for some Steel materials.
The materials are all in specific sizes.

What i want to do is, as i input the length, width and height of the structure in the spreadsheet, the Material Quantity List will generate the quantity of each piece of material i will need.

Does anybody know of a formula for this. I have been trying to use the IF function and getting absolutely nowhere, all suggestions will be highly appreciated!!

Hi Excel experts,
I am working on a worksheet, and would like to have an entire row transferred to another worksheet based upon a certain cell's value.

Having searched through the many solved threads on this site, I attempted to customize some of the code to my worksheet. Not being proficient in Macro/VBA, I failed. I figured I would ask for help, and see if anyone can provide what I am looking for.

Basically, I am attempting to construct a "work in process" file, and would like all completed work to be deleted from the work in process sheet, and transferred to a sheet that contains a running list of all work completed.

Attached is an example of what I am working on. I would like Column Q (Status) to determine if a row can be moved to a sheet that contains the list of all work completed, and eliminated from the original sheet. Once Status is updated to "Complete", it would be helpful to be able to run a macro/click a button that would perform the transfer.

Can anyone assist?

Thanks!


I have an excel worksheet that adds two other worksheets in a data
triangle. I copied it to create a new data set and used find &
replace to change the worksheet references to the new ones.

The cells still contain the result of the old formula referring to the
previous worksheets. The only way I can get the formula to return the
correct result is to edit (F2) each cell and press enter. Calc now
(F9) does nothing.

I've seen this before, but this time, I need to calculate many
thousands of cells and don't have time for this workaround.

Any ideas?

Thanks.

Hi can someone help please?

I have two worksheets and wish to copy rows from worksheet 1 to worksheet 2 if a condition is met in one of the cells within that row.

Hope that makes sense.

Thanks

I have workbook in which I want to save a specific worksheet to a new file with only the values saved - all data in this worksheet are references to cells on another worksheet, which is using VLOOKUP to pull data from a database.

Found the following code and it gets me close, but it copies the cell references, not the values. It also allows me to specify the file name from a cell reference.

I want the new workbook file to simply be saved, not opened, and a message box to display stating where the file was saved (will always be in the same location on the LAN).

What modifications do I make to this to get this to work per above requirements?

Sub CopyMe()
Dim SaveMeAs As String
SaveMeAs = Sheets("Sheet1").Range("B2").Text
Sheets("Sheet3").Copy
ActiveWorkbook.SaveAs Filename:="C:\My Documents\" & SaveMeAs
End Sub
