四角形の角を削りたいです。 削った後の形が三角形になるようなイメージにするにはどのような操作をしますか？

Design Technology の Pad Style でレジスト無し（Solder Mask無し）のビアを設定したいのですが、どのようにすれば良いか教えて頂けると幸いです。

Hallo. Muss ein Beispiel rechnen, verstehe es aber nicht. Kann mir wer helfen? Angabe und Lösungen sind im Anhang, brauche nur den Rechenweg. Danke LG

Hello, I want to use custom columns for my BOM, I add some custom component properties and add column to my BOM.   But the "custom component properties" created are only visible for the component on which i created those properties. How can I create a property which can be visible for all my parts. Morevoer, I don't understand why the component property doesn't appears for all my part and why it can be different between 2 parts by default :   Thank you for your help!

Hello, I have purchased the Exchange add-on module 8523012. I have received an email containing the download link and serial number, and have downloaded and unzipped the DSMUpgrade_1.0 .exe file, but whenever I run the .exe file,-"No DesignSpark Mechanical installation was found. The upgrade cannot continue." message Will be displayed.   I confirm that I have used a valid DesignSpark Mechanical. I desperately need the extra features provided by the add-on, and hope to get your help as soon as possible. We would be very grateful. Best regard, HP.HO

Hi, I downloaded the DS file, opened it with 7UP (unzipped it) and clicked on the app. When I click on step 1 start I get this error Is there something that I can do to fix this problem? Thanks, Dan

At the begining of downloading mechanical I get this pop up error message: Gbjy9yp8zip.part could not be saved because the source file could not be read screenshot attached. I have high speed fiber internet, connection is solid

Hello everyone, first time here. I created my circuits with boards and schematic but now I want all of them on one project. It is possible to make something like that in PCB design spark using previously made projects? I've never done that, so I would need guidance, please help me. Thanks in advance.

Consider a LCD screen add on board that has 4 mounting holes and a connection header as a single component, that then has other components under it on the board under design. So, technically it is a component under a component. ?How to avoid the spacing errors? The first idea is only include the attaching header in the LCD component, but then the mounting screw holes for the LCD can not be controlled. Any ideas ?

Hi. It's my first time plan to use linear solenoid. I plan to use for verticle lock application. when energize solenoid pulls in, de-energize spring return home which will extend solenoid fully. Based on RS specs, squared housing have more pull force than tabular. my concern are: 1. is it good to hold current for along time to pull in linear solenoid? (for my application: keep unlock always energize) 2. is it good to use only half stroke of the solenoid? or better design to always pulls fully 3. some of RS linear solenoid does'nt have power (watt) for specific product but got same power-force graph. how to diffrenciate the variance?  thanks dan

I would like to create a power back-up for my gas boiler, so that I can still have heating if the grid goes down. Do I just need an Uninterruptable Power Supply? And if so, for approximately how long will this run a boiler which requires 140W? Thank you. Tim

If I rename a PCB symbol in the Library, then any components that use the old symbol name end up broken - i.e. the components still refer to the old symbol name in the Package details. Is there a way to automatically update symbol names in existing component packages when symbols are renamed? Doing this manually is time consuming and it's difficult to locate all the components in the libraries that reference the changed symbols.  

Hi, I am just starting on the CNC journey with building, under some guidance, a small mill. The capability will have 3 axes so am looking to do 3-D drawings with mulitple components. I'm reasonably familiar with doing this the traditional way - on paper - or with tools such as visio; but this is the first foray into CAD. So, what do I need to know to get started - assuming I can convert these drawings into suitable files to drive the mill?  I thought part 1 would be to redraw the mill design. It has lots of straight lines and a few holes in multiple parts for assembly. Cheers

I'm trying to construct a piece of 5mmØ 0.2mm wall thickness tube that has been squashed a little to make it triangular. I constructed this measured the perimeter and found it was a couple of mm short, so I thought I'd  make use of the maintain connectivity 'feature' and move the radii out a little: Bah, humbug!
