CAD

Hi, all.  I have just started using Mathcad. The problem below is driving me crazy. Any idea why it is giving me the wrong output?  See below. I have also attached the Mathcad file. Incorrect answer:Correct output: RegardsCP  

Hello there, I'm currently dimensioning an epicyclic gear reduction system and I was wondering if it was possible to use the CREO 9 (the version used in my school) parametric functions to dimension this system directly in the assembly. For example, for a given number of teeth on the sun gear, an input torque and an output torque, it might be possible to calculate the planet gear teeth as well as those of the ring gear, and thus directly modify their dimensions. (including the center distance between the gears, the pitch, tip and root diameters, etc.) I've already done a few tests but they didn't lead to anything except errors. Thank you in advance for your answers.

If you click on License under Options in Prime, a host ID is also displayed. I was of the opinion that this is the MAC address, called 'primary' by PTC, for which the current license was generated.But apparently there is some confusion here and it is a constantly changing fantasy MAC!!? I can't believe that this is intentional behavior, which is why I classify it as a bug. I am not sure but i think that in older versions of Prime the correct MAC was shown, the one the license was created for. I recently had to generate a new license and had it created for the one that was displayed. Of course this license file did not work. This was quite annoying, as license management is not exactly one of the easiest features on the PTC support sites and it took me some time and effort to finally move the license to the correct MAC.  

Requirement is to update CAD template of a Project.Initially, these CAD template is created using a source CAD file (drawing) which includes a format file.We have new format file and drawing file. Able to update them from A.1 to A.2?But how will the CAD template created in Project using A.1 version be updated?We don't have an option to choose source CAD file when checked-out? Any help would be appreciated.

Hi there, I have this plot which has ( x, y ) and A and B are points in this plot>>> I want to show this point in different colour and then draw the vector of them ABand then I have  another x and y ( x;cpt , y;cpt different values) I want to show point C,cpt in the same previous plot then draw the vector component of AB and C,cptthe result should look something like this:not necessarily the same ,but I need to show the vectors Thanks in advanceprime 9 

Creo: 10.0.0.0 education version Hello everyone, i am trying to create a sweep in the shape shown here:I tried using the sweep blend feature but this results in weird interpolations between the segments. I know that by just sweeping from one section to another the interpolation is linear, but i want some sort of spline as shown in the sketches. Here is the image showing the interpolation. Using the blend feature to control the sketch with trajectories doesn't work properly. I do not know why the trajectories are ignored here, but when i change the sketch to an ellipse at leas one trajectory is followed.Maybe someone can help me with this, since i am out of ideas what parameters i need to change in these features to get my desired result.  

I have an input matrix from actual test data, where I have taken out 5 test dataset(Speed and 5 pressures), showing first line belowI now want to do some calculations, get all the differntial pressures for example : I know i can do like this: but it would be much nicer to display the result as a table with proper colum headers and units, how can i achieve this?  

Hello, Software used: Creo 8.0.When I set up combined state view in the model I can show different dimensions and annotations in each combined state view, but when add a new view to the drawing and select the combined state view, the annotations and dimensions are not displayed in the drawing as they are in the model.  When I select show model annotations for the drawing view it shows every single dimension available not just the annotations and dimension I displayed in the Model according to the combined state view. In older versions of Creo, this was possible, not sure if there is a setting that should be changed in new versions. Thanks,     

I have data in excel and I want to copy that data and use as matrix in Mathcad prime ? Is this something possible how can I do that? Let's say I have 10 rows and 100 columns and want to copy paste it in matrix is there a simpler way? Due to the nature of data I am unable to share here if anyone has a sample data to show me how that can be done it would be great!

Hi, I am trying to run the torque analysis on the flange assembly with stiffeners welded using weld features. Unfortunately I am getting errors like "Problems were encountered while preprocessingthe features for the highlighted surface."    I could not understand the root cause of the errors. please help me diagnose the issue.  Regards,Kishore

Hi There,I want to know the difference between the MathCAD and the Students version MathCAD.Thank you

I recently upgraded my c:/ drive and Mathcad no longer runs. It fails the license. I get a message "The license you have requested contains an error." When I run the .licensing setup wizard I get a server error of 403 Forbidden. It was working fine prior to the SSD upgrade. Please help!

I have Mathcad 9.0 but bought the Prime 10 Student edition. I'm trying to upgrade/activate the license. Do I need to uninstall the 9.0 and install the 10?Also I never received my product code. I received the payment confirmation email where it stated "You will receive detailed information on the delivery in a separate e-mail that was sent at the same time as this e-mail." However, I never received a separate email. I can't find a place to submit a ticket. The only place I can find for support requires a product code.

Hi I am new to Mathcad Prime and I'm trying to solve a kinematics problem, and I really need help. I want to multiply 3 nested arrays, but in step 4 I encountered the error "These arrays elements must be scalars. They cannot be vectors or matrices." I suspected it was because they are nested arrays, so I tried to convert the nested array H1 into a matrix with a code I found online and now I encountered the error "This value must be a vector,"Any help is appreciatedThank you

If I am not a designer, but an analyst that adds cad to my workspace and labels, takes pictures, makes leader notes for my own reports, is there a way to preserve items like notes, model colors, after i perform a model updated to check new geometry, fasteners, materials.  I usually work in a separate self made assembly, so technically i could make items in this assembly that are unique and don't belong to the real cad being built but it seems like notes refer to part features.

I have been using mathcad for many years, its been my go to software to help me think and sort out problems. Very recently I moved to Mathcad prime 3. I am unbelievably dissapointed. Yes it looks pretty , but its so hard to do anything. I wanted to display arrays as a picture , as I have done for many years. You cant do this. You have to save the data to a file, then read in the file in to a picture which has browsed a filename. then it does not update when you change the data in the file. Its awful and unusable in this application. I have had to revert to a pre prime version as this actually does what I need it to do. I cant believe we are on prime 3 and this is not sorted out.Help doesn't work either. Prime really is a backward step and I would not recommend it to anyone - are you listening PTC. I have colleagues who feel exactly the same. If anyone can suggest how to view 2D arrays as pictures in a usable way I would like to find out.

I am making sweeps and swept blends using datum points then creating a curve through those points then sweeping along that curve. The datum points exist as one feature, Is it possible to edit the feature to insert a point at the start or halfway down the list? I'd like to add a point after point 7 in the screenshotCurrently I only seem to be able to add a point at the end of the list.I'm using creo 8.0Thanks in advance 

When creating a counterbore style pin hole with IFX, the software defaults the 'thru' diameter (labelled 'counterbore diameter' in the UI) to 1/2 of the nominal pin diameter.  Our manufacturing standard requires a different diameter - is there a hole chart column that can be used to drive this dimension to a specific value so that the user doesn't have to manually change it every time?We have tested with the known hole chart columns and none seem to work.We are currently running Creo Parametric 10.0.5.0.

Hello everyone,in the attached file, the program should loop through length of dS and store the values in RA. could someone explain me, why the loop is not workingattached the Mathcad 10 file.

I am having trouble understanding why I can't get a solution using the defined variables but am able to get one when I put in a value for the variable.  My issue arises because the values X, Y and Z depend on Twall.  I want to be able to loop this with an update to Twall at each dt.  Any help would be appreciated. mathcad prime9 .    

I have a rivet I want to show in an assembly. The rivet data was 'imported'. In order to show the installed/deformed position, I added a 'deformed' feature that can be controlled by a flexible dimension. The Master Rep displays the 'imported' rivet AND the deformed geometry. I created a Simplified Rep (INSTALLED) which displays the deformed rivet without the 'imported' rivet. So far, so good!   The flexible dimension will allow me to display a deformed/installed rivet for different panel thicknesses. When I add 3 flexible rivets into my assembly, I can change their dimension to fit 3 different panel thicknesses (0.75-inch, 1.00-inch, 1.50-inch). However, the display shows both the 'imported' rivet AND the deformed/installed rivet data. When I active the INSTALLED Rep, all 3 rivets default to the original dimension (1.50-inch) and do not hold their flexible inputs (0.75-inch, 1.00-inch, 1.50-inch).   Why won't a flexible dimension hold when changing the assembly to a simp

I am currently using Creo Parametric 7.0. I want to switch between open windows using Ctrl + Tab like every single other software does. I searched for a while and found no options in the software or even anyone asking about it. Is there some way I can make this a keyboard shortcut or something? Is this feature just not integrated into Creo at all?   

I want to show a formula as a step for reverence, not have MaffCad try and solve it,Can't see how to do it, there must be a simple way to add a formula like a text box?

Hello.We've recently switched from Creo4 to Creo9, and in Creo9 I'm facing a challenge I never had in 4:In part and assembly design, when I hover over geometry, some of the surfaces appear to be highlighted in "broken" or xxx-patterned highlight, like below: while other are fully shaded, as if masked with transparent layer : for both, selection "repaints" them just fine with selection color. Went trough all reasonable config options I could think of, all regarding highlight, transparency, selection, with no visible changes. I'm looking for a method to achieve consistency in the highlight, preferably with all being the second option, without xxx pattern.Thanks 🙂   

Hi,the tool path of volume roughing sometimes works from the outside to inside (correct) and other time as opposed to.I attached file manufacturing with a video for try the problem.The support dosn't help me because for they are correct this Works to product specification for Creo Parametric 😡 😡 😡 😡 😡.How can do it the sequence in other way? Thanks
