This month’s challenge is related to electrical engineering. We have a simple circuit with an electrical potential of 220 Volts. Initially we have a single 10 Ohm resistor. Then we add a second resistor in parallel, with 10% higher resistance. Then we add a third resistor in parallel, with 10% higher resistance than the previous resistor. And so on. Calculate the current in the circuit for the single resistor case. Calculate the resistance of each additional resistor and current through each resistor for 2, 3, 4, 5, and 10 resistors in parallel. Can you write a function or program that calculates the resistance of each resistor and current through each resistor for n resistors in parallel? These calculations are fairly straightforward, so it will be interesting to see what tools – vectors, matrices, loops, plots, charts, etc. – that you use to solve the problem. As always, how you document your calculations is important as your worksheet will be visible to the community. Here is an e

This may be a somewhat silly question because I'm relatively new to Creo, but for some reason I can't project my equation-defined datum curves into a sketch. I have followed the support page for this exact process but when I try to select the curves for projection into my sketch, nothing happens and the curves aren't selectable in the modeling window. For reference, I am using Creo Parametric 7.0 and am trying to design something defined by epicycloid and hypocycloid curves.

I am using Creo Parametric Release 6.0 and Datecode6.0.5.1I have an assembly that has 1 out of several simplified reps using automatic reps instead of the user-defined reps that it is supposed to use. I found a reference in the help docs describing how to open a simplified rep using automatic reps, which is temporary, and how to make it permanent, but nothing on how to revert it back to using user-defined reps. Screenshot of 2 simplified reps' model trees attached. I tried redefining the first level subassemblies to use the correct user-defined reps, but the second and lower subs still use automatic. I have checked up to 5 levels deep.

Hi! Why, in figure 29 of the attached worksheet, do the phases not coincide? And in general, if I have made any mistakes please let me know. Thanks very much to those who will answer.

Hello...just started back into MC and have a question re; this error I'm getting re: a summation:Why does is it say the variable is undefined when it IS defined? what am i missing?I enclosed a snapshot of what i'm talking aboutThanks for any help?

I am using Creo Parametric Release 8.0 and Datecode8.0.6.0We are trying to get the license file/server to load the Design Premium Professional first, then load the design essentials licensesCurrently we have 2 floating for Design essentials and 1 for Design Premium Pro the license file is installed on the server and when people run the parametric link on the desktop it loads desin Ess. not Premium. and when you got to use functions under the premium license it fails saying there are no options loaded. even when there is no one having the design premium license checked out. The only way we can get it to run right is to have someone log into two workstations using up the design ess licenses and then running Creo it will check out the premium license and allow us to use the advanced features. Is there a way to add something to the options file that tells it to either choose or pick the Premium by default?

I am using Creo Parametric Release 7.0 and Datecode7.0.5.0I received a file (.asm) that contains an sub-assembly with a icon that I do not know. Similar icon to assembly type, but gray color...What is it? how is it created and how is it modified?

My client often sends us their sheet metal part in STEP, that we import in Creo, and we transform in Sheet metal. When we have hole with Countersink, the Convert to sheet metal will take the size of the hole on the side chosen, and convert in simple hole, then if you chose the wrong side, the hole will be on the size of the Countersink instead of the hole,  I there a way to keep the countersink after the Convert to sheet metal feature?  In example, my client has forgot to specify on their drawing (drawing with only a few important dimension) on his part. The part is big with small hole, and I don't have seen the countersink, and we have cut the part with the hole at the bigger size.  Normally, I see it, and after the Convert to sheet metal feature, I have to find the hole, and add hole feature again to add the Countersink. If there was a way to keep the feature, this will help greatly with the import of sheet metal part. 

Hello.Im trying to set up the drawing templates for SmartELECTRODE, but I've got some difficulties I hope someone can help me with. The problem is when trying to add EDM positions to the drawing, using a custom (repeat region) table, it will add positions of ALL electrodes, where I only want to add the positions of the electrode on the current drawing (I've chosen option "One sheet per model"). My template looks like this: TemplateAnd this is the result:ResultAnd its funny because if I add my custom table (which I've saved as a .tbl file) after the drawing is the created by SmartELECTRODE, this is what I get:Table added manually (correct)Another "weird" thing, there's probably a reason, is that when using the table from the original drawing template (see picture), Table template in ASM_EDM standard drawingthe correct values will be added to the table. (see picture)Result using standard drawing table.Also when this is fixed (if it possible) I'd like to merge the "ASM_EDM" draw

Hello all,I am a newbie here and I am using Creo Illustarte. So I hope that I will ask correctly.My question:Sometimes Illustrate displays a curve in an edgy way.See my attached example. The cap and the O-ring are actually round.How can I fix this?

During Creo additive manufacturing, most guides export files to 3mf. However, only G-code can be read when reading from a 3D printer afterwards. Is there a way to export it directly from Creo to G-code?  I am currently using creo 9.0.

Hello, We migrated from Creo3 to Creo8, and the thing that is very annoying and i cant turn it off, is next. When I work on assembly and than click on part in graphic window, it automaticaly jumps on that part in model tree also. In Creo3 it did not jump on that part in model tree, You had to right click on the part in graphic window, and than there was option in dropdown menu 'Show part in model tree'. I would like this function back in Creo8, is there a way? Automatic 'jumping' is sometimes useful, often it is not. I seem to spend 30% of my time just scrolling through  model tree to find things. I have a lot of skeleton sketches in assembly model tree, that are used on multiple parts.  Now averytime I activate the part in graphic window, it jumps to that specific part  in model tree, and I have to find that sketch so i can choose it (for a pattern for example) again.

Hello, in my BOM I can see that a specific part appears twice, so it has to entries in the BOM.I used it in total 24 times in my assembly. One entry has 16 parts (qty), the other one 8. It is for sure excatly the same part (.prt), still I am not able to combine it. I saw the following article: https://community.ptc.com/t5/3D-Part-Assembly-Design/BOM-not-merging-part-quantities/td-p/571318   I did excatly the same, still the problem occurs. Let me know if you need some files, but the file is quite a big assembly with many many parts.   Greetings Spedex

ModelCHECK is telling me that I have views that do not have scale assigned, but my views DO have Default scale assigned. Is VIEW_SCALE working as intended here? I would think that Default scale would count as an assigned scale.  

I don't own a product code for my student Mathcad and I can't activate the license I received via email.

Although I can create a plot, I am not able to format it. The Symbol, Line Style, Color Scheme, Trace Thickness, and Surface Fill options are all grayed out. Only can change Trace Color.

I am trying to create a drawing template that uses a simplified rep for a view and a bom table that only shows the items shown in the simplified rep.  My template uses the simplified rep but the BOM table still shows all the items and qty's in the entire assembly.  Any suggestions on how to acheive this?   Thanks, Brian

Hello everyone. I publish a work done with MATHCAD 15. I don't think you can do the same with PRIME. What do you think about it?      

Hello,I am reasonably new to using MathCad and I am experiencing an issue when trying to solve the programs on page 7, 8 and 9 of the attached work sheet. I am looking for outputs to the 'Column' 'Lp' and 'Lr' functions for a range of values, i. However, I am being met with the error message 'This array index is invalid for this array'.Any advice is much appreciated as I am still learning the software.Thanks in advance

I am using Creo Parametric Release 6.0 and Datecode6.0.5.1One of the users is unable to import the word documents inside the Creo drawing. The user is able to import only once when system is restarted and unable to import the document again.

I'm using a surface to 'trim' the solid by solidify the surface, but the solidfication will always consume the surface after it's done. What I want is to keep the surface, so that I can still use it later. I checked also the configurations, there's no such an option.Is there a way to do so? Thanks.
