nu reusesc sa obtin perioada de 30 de zile gratuita la Matchadprime 11. Am nevoie de o licenta. Am primit pe email dar e doar un pdf si nici nu il pot deschide. Sau poate imi trebuie un key product de 22 de caractere care sa pot activa perioada de 30 de zile gratuita.

I'm using MathCAD 9.0.0.0. How come MathCAD is unable to solve these simple equations? 

See attached. I'm using MathCAD 9.0.0.0 and am having a few problems...Is there a way to put a bar above the variable Yf so it looks like ? I found something online about using the Windows Character  Map and I can copy the bar symbol, but it won't paste in MathCAD.The last few equations are showing values with a long trail of decimal places following "explicit,ALL." Is there a way to limit it to displaying only 3 or4 decimals? I set it in "Math Formatting > Results > Display Precision," but that seems to have no effect.Alternatively, is there a way to break long equations to have them continued on the next line? The following values are off...T=19.76*10^3 and it should be 19,786 N-m. That's only slightly off.P=1.3*10^6 W and it should be 207,201 N-m/s(W). That's way off.HP=1.744*10^3 and it should be 278 hp. That's way off. Is that all because of a rounding error, Something I did wrong, or is MathCAD misinterpreting one of my variables?Thanks,      &

In Mathcad 15, after selecting a portion of an equation with the spacebar, you could hit Insert on the keyboard to toggle between inserting before or after the selection. It doesn't seem to work in Prime. Is there a way to accomplish this, or do you just have to click closer to the beginning/end before hitting the spacebar?

I have a table that we use to capture Rev History.  Whenever we add a row to this table, the text size and text alignment does not carry the alignment from the previous row.  Is there a way to set it the text size and alignment (or even style) for each column so that newly added rows don't need to be specifically defined? The first row under the headers shows how I want ever added row to behave.  The second row shows what I am currently getting in regards to Vertical Alignment, Horizontal Alignment, and Text Size. Currently using Creo 10.0 

How to compose the tree data structure in Creo UI component Tree. I am using OTK Java.With these classes it provide, I don't know how to add childNode or set parentNode. I can only display one node in the tree which might be the root node. This is my code. package com.ptc.otkjavaexamples.ui;/*--------------------------------------------------------------------------*\ | | Module Details: | | Name: TechniqueTree.java | | Purpose: Display the TechniqueTree dialog \*--------------------------------------------------------------------------*/ import com.ptc.cipjava.jxthrowable; import com.ptc.pfc.pfcCommand.DefaultUICommandActionListener; import com.ptc.uifc.uifcComponent.*; import com.ptc.uifc.uifcCore.ItemPositionData; import com.ptc.uifc.uifcCore.uifcCore; import com.ptc.uifc.uifcDialog.*; import com.ptc.uifc.uifcInputPanel.*; import com.ptc.uifc.uifcPushButton.*; import com.ptc.uifc.uifcTree.*; public class TechniqueTree extends DefaultUICommandActionListener { private String

While working on an answer to a question here in the forum, I noticed two bugs in Prime concerning the symbolics. I could not be bothered to report them the "official" way (too complicated, I am too old to be forced to jump through that many loops) so I post them here for your information and of course for PTC staff if they really are interested to improve their software (just joking...) Both bugs are already present in Prime 6 and still are in Prime 10.   Bug #1: Simplification of an expression using "floor" and the Heaviside function returns a wrong result! BTW, the bug is due to the 'new' symbolics. When we switch back and use the legacy symbolics (only available in P6 and below) we get a correct result     Bug #2 "clear.sym" does not clear a range variable. It should make it undefined for symbolic operations. "clear" works OK, but it also makes the variable undefined for the numerics. Interestingly the operation works as it should when a second variable is added

I have a vector of data points, and I'd like to be able to selectively plot just a portion of that vector. For example, I have a vector value:=[2 3 5 8 13 21] and I want to plot just elements 2, 3, and 4. I created an index:=[2 3 4] and tried to plot value[index on the vertical axis. I've tried both the chart component and the native plotting tool, and neither worked. The only way I've figured out how to do this is to write a mathcad program to fill a third vector with just the portion that I wish to plot, then plot that third vector. That's awkward. Can you tell me what I'm doing wrong?

I have tried multiple times to download the current version of MathCAD Express, but the system has never sent the promised "installation" EMail. I have requested help from sales, but no response. I've been using MathCAD since version2 in the 1980s, but lost access to the "home use" license when I retired a few years ago. I just need MathCAD now for hobby use, with no commercial or professional usage at all. The computer that the home use version was installed on is no longer functional, so I need a copy for the new computer. Most of my hobby stuff is in MathCAD15, some is in Prime 5-8. I am in your system as PJR51@live.com, formerly Paul.Rebstock@NRC.gov. The live.com account is still active, the NRC.gov account was closed when I retired. My cell phone is 240-393-3704.How can I get the current version? Can I install it on both my laptop and my Microsoft Surface?

I have done a Google search as well as reviewing PTC's documentation online but haven't discovered exactly how to do that which likely isn't that difficult.I want to have my "Start In" location to be easily accessible and my config.pro burrowed in deeper but in a location that would not change after new Creo installs. Below shows where I would like the respective directory locations to be:Start In: C:/CurrentWorkConfig.pro: C:/CurrentWork/Creo/Settings There is one PTC help file that seems to suggest how this might be done, but I don't know where the suggested line would get applied.Alternate Path—You can set the environment variable PTC_CREO_ALT_SETTINGS_PATH to point to an alternative path where you store your configuration files. This path could be set to any mapped network drive or a shared OneDrive folder.The following files are read automatically from the directory that PTC_CREO_ALT_SETTINGS_PATH points to:◦config.pro◦config.sup◦creo_parametric_admin

I am looking for a way to search in a drawing for a table with the first cell has the content "Rev." and if this table is found, a new table should be added.Below script finds the table, but it seems my command table.InsertRow() seems to be failing.Can somebody help me?(The table has 4 columns, if this has any influence.) function addRowToRevTables(drawing) {    try {        // Get all tables in the drawing        var tables = drawing.ListTables();         for (var i = 0; i < tables.Count; i++) {            var table = tables.Item(i);             try {                // Get text from cell(1,1)                var cell = pfcCreate("pfcTableCell").Create(1, 1);                var mode = pfcCreate("pfcParamMode").DWGTABLE_NORM

I was trying my first Simulation in Creo Ansys Simulation, facing an issue during creation of mesh. I checked with multiple YouTube video but still I could get the solution."Material Some bodies or simulation objects in your modeldo not have a valid material type/elasticity model assigned."Please help me to resolve.  I am using Creo 10.0.7.0

Guten Tag,  Ich versuche gerade mithilfe des Generativen Designs ein Bauteil zu optimieren.Leider erzeugt Creo keine neue Geometrie. Es wird nur ein Bauteil erzeugt, das ausschließlich die beibehaltene Geometrie beinhaltet, zwischen diesen beiden Körpern wird keine Verbindung erstellt. Die Optimierung zeigt auch nur eine Zeit von 00:01. 

Hi, I am working on IFX custom library creation for my company.I have more than 1300 screws with 4-5 categories .I can not use dat files with category name and multiple parts from same category in the file. As i just dont have differentiation on Top category, i have different variations in sizes, lengths, then material, finish, drive types. I am now creating individual .dat file with info value placed in them showing part number, its size, length, material, finish, drive types.So, my top level category shows around 200 screws in one category dropdown,then each row shows, its name and other attributes. Is their any way we can add multiple options of dropdowns to select from, like length, or thread what we have. SO extra dropdowns for material, drive type. 

I am using Creo Parametric Release 6.0 and Datecode6.0.4.01、二维绘图下草绘和注释里“绘制组”命令的API是否有开放（功能开发需要）2、或者能否提供和设置组达到同等效果（绑定的对象可以一同操作）的且提供了API可用于开发的方法。

Hey I have a code to check if there is a family table in the part. This will in Creo 5 return the name of the instance if it ends with "flat" or "flat1"But in Creo 11 I get a fatal error.I thing it is because I don't have a Family table in the part.How can I check of the part have a Family table? FamilyMember familyMember = (Solid) model;FamilyTableRows familyTableRows = familyMember.ListRows();// Find if a flat version existtubefor (int i = 0; i < familyTableRows.getarraysize(); i++) {FamilyTableRow familyTableRow = familyTableRows.get(i);if (familyTableRow.GetInstanceName().contains("FLAT1")) flat_name = familyTableRow.GetInstanceName();else if (familyTableRow.GetInstanceName().contains("FLAT")) flat_name = familyTableRow.GetInstanceName();if (!"".equals(flat_name)) break;}

Hello all,   A question about drawings. Why hole axis are always orientend horizontal/vertical independently the way we created the holes ? On the capture below as you can see hole axis are always horizontal/vertical. I would like to have axis orientend like the view on the right but on the left view. Is it possible ? Thanks

I have imported a DXF file in CREO and thus created an extrude out of this DXF file, using the PROJECT function.To distinguish this from a regular CREO extrude, I will call this non-native CREO extrude a DXF-import extrude (for lack of a better name).If it already has a name I will stand corrected.  Anyway, this DXF-import extrude is impossible to work with.I am trying to make it accept a different color than the background, but it does not work with regular means -- this DXF-import extrude seems to be a surface that CREO cannot handle like any other extrude generated directly in CREO without an external import. Is there a way to make this DXF-import extrude behave?Maybe create another native CREO generated surface, identical with the DXF-import one and transparently on top of said DXF-import extrude, that would be more amenable to work with?I have attached the PNG file (source for DXF), the DXF file, the part file with the DXF-import extrude and two

HI, First time user of the GD&T advisor, trying to add a position tolerance to one half of a hole pair (for a shaft) and a second position tolerance to the second hole of the pair, A simplified version of my part is shown in the attached image. Currently running Creo 11.0.2.0 Hole was modelled as a single hole for both pairs. With the model setup like this I am unable to select either the right or left hole to assign a tolerance. Am I missing something here or is the only way to get this working by modelling this as 2 separate holes? Thanks 

Whilst writing a string replace function for Mathcad Express, I found what seems to be a problem with the string function search.   I wanted to check a string for the existence of the Unicode characters for 11 (↊) and 12 (↋) in the duodecimal system ... and it found them everywhere even when they weren't there at all.   Has this been noticed before?  Have I made some kind of error or unwitting assumption?     Cheers,   Stuart   (The simple recursive algorithm shown above is O(n) and only good for strings shorter than about 4000 characters (ie, under Mathcad's recursion depth limit.   A slightly more complicated algorithm would use a binary-division algorithm to reduce the recursion stack to O(log n), which will handle much longer strings)

If there is a way to display the values of variables inside a block in mathcad 15?

This file is in MathCAD 9, but I'm experiencing the same issue in MathCAD 10. I believe MathCAD is misrepresenting the units. See attached. "Hmp" and "TH" have the wrong values when comparing with example 11.2 at the bottom. I rewrote them as H and T next to them. I substituted "m" and "Ump" for the actual values of 100000 and 1035 and the answers came out correct. So, something is wrong with how "m" and "Ump" are represented.

Hi,Can anybody solve equation ? Solution is x =1, but Mathcad doesn't see this solution ...  

I'm trying to pass on a variable as a string to another mathcad Prime sheet.  VAY is a number defined above in calculations within the sheet.  I don't want the evaluated value but the variable itself.  There should be a function to do just that.  See screen shot.

I am working with Creo 8. I would like to implement a dialog with tree view in it. The tree has 3 columns. I have spent few of hours trying to understand API to create and populate tree. But not able to figure how to do it. With C++ I wasn't even able to add node to tree. With C I could add node but not able to figure how to add column. If anyone has tried this already I would appreciate the help in from of sample code. FWIW - For C I have following working code to add node -     auto status = ProUITreeColumnCreate("dialog_material_assign_assembly",                                        "MatAssignTree", nullptr, L"Test", 10,                                        PROUITREECOL_LEFT);    status = ProUITreeNodeInsert("dialog_material_assign_assembly",
