I am going to serve as teacher assistant in a construcion course at my universty were i will be grading beam design assigment.

I have calculated everything in mathcad 15 so far. The students will have to determine the height of the beam by fullfilling a criteria.

I would like to put my mathcad file on the internet were the students can select the diffrent parameters each student have. mostly diffrent material properties

and there they can see if they have choosen a height that fullfilles the specifed criterita.

Basiclly I want the student to choose their parameters from a dropdown menu or something and then the calculations will be performed based on that and

this i want them to be able to do on a webpage. is that possible?

Prime 2 won't save my changes - Help!!

≪ Previous: ... or I do not understand someone?

I have a large worksheet that was converted from 15.

Today I made a number of corrections to some of the assumptions that new data has clarified.

When I try to save the file, I'm getting this error:

similar to the error I receive when I'm trying to open a Prime 3 file...

the information in the log file is uninspiring.

here's an extract:

Exception data:

I am going to try a line by line check between the current saved file & the modified version, but it is a mammoth task and since I don't know what I'm looking for I don't hold much hope for success.

Has anyone seen anything like this or any suggestions how to preserve the changes that I've made?

Thanks

I have been working on a document for several hours. I set auto save at 4 minutes and got a popup every 4 minutes with the save address on it. At the end of that time I closed the system down, came back later, opened the file and nothing had been saved. I looked in the default save location and the file was not there either. This is a serious problem. I have raised the issue with my reseller but not sure what they can do. Anyone else had this problem ? PTC needs to look at this. I noticed the save address on the popup said Mathcad 14. I have Mathcad 15. The reseller said this could be the problem but offered no solution.

Im still working on a routine and im stucking in defining a routine for each row of the vector.

I need to define a certain condition and apply it to every row of the vectors

The rows are depending on the Loadcases, which are read in mathcad.

I still dont really understand :-(

In this case i need to write the maximum value of the calculated 5 pressures to excel for every loadcase.

Referencing Worksheet of Embedded Excel Component in Mathcad

≫ Next: MathCAD Prime 3.0 & Roark Toolkit, possible?

≪ Previous: Unit Conversation Issue.

Hi!

I am using Mathcad 15 and Excel 2013.

I need help regarding this. This problem is only illustrative of the one I want to solve.

Suppose that I have a Mathcad file wherein I am embedding an Excel Component. (See attachment).

Say if the value of Cell A1 is not "Happy", Picture 1 will be hidden. It will be shown otherwise.

Normally, it would be easy to do this in Excel. The code would be:

Private Sub Worksheet_Change(ByVal Target As Range)

If Cells(1, 1).Value = "Happy" Then

ActiveSheet.Pictures("Picture 1").Visible = True

Else

ActiveSheet.Pictures("Picture 1").Visible = False

End If

End Sub

Now, I am trying to make this code run inside the Mathcad embedded excel file by coding it there. However, I am confronted with the error:

I am thinking that maybe I cannot refer to the embedded sheet as simply "Activesheet."

Can anyone help me sort this out?

Thank you very much!

≪ Previous: Referencing Worksheet of Embedded Excel Component in Mathcad

Hi,

If someone could please advise on the followings.

Our company bought Mathcad Prime 3.0 licenses.

One of our users (based in Britain) wants to know if Roark Toolkit is available in Mathcad Prime 3.0.

e opened and tested, but did not see Roark Toolkit (or say this function) in it.

Some suggestion in the internet indicates that Roark Toolkit was available in old Mathcad Prime, and we'll have to pay additional cost for getting it in Mathcad Prime 3.0.

Is this true?

If so, could someone please give a official link for all the information, including price, installation guide, how to buy it...etc?

Thanks!

Hi,

a very simple problem:

I want to flip a vector, that means reverse the sequence of its elements for example (1,2,3) --> (3,2,1). I tried several methods, none works really.

The problem is, the result vector seems to be ok, but if I use it in other expressions together with the vectorize operator MathCad says always this value has to be a vector.

I am using Prime 3.0. Thanks

Hi all,

I have been using MathCad Prime 3.1 for some weeks: I recently implemented a solve block in which I defined a system of ODEs with guess values and initial conditions: the solution is calculated via "odesolve" function. Since I need to have the time and initial conditions as parameters, I was wondering how to define the solve block as a function, in order to recall it wherever within my worksheet.

Does anyone know how to do this?

Thanks a lot!
