我昨天将我用于主要设计的电脑升级到Windows11系统，电脑中其他软件都可以正常打开，唯独DSM打不开，请指点应该如何操作才能恢复正常。

How much embedded RAM is integrated into the EP4CE55F23I7N?

Hi all   I'm trying to make a step file, which my customers can use for getting the outside measurements. But I would like to lock the file, so they cant open and se all the parts inside. Anyone knows how to do this?   Best regard  Martin

Nichia uses irregularly shaped pads for its 757 package LEDs (see image). https://led-ld.nichia.co.jp/en/product/led_product_data.html?type=NF2W757GR-V5&kbn=0 How do you create them?

I spend a lot of time creating assemblies from parts. The default "select" is the object but mostly I want to move/align components (object in its box). If I choose select component the software always seems to revert back to select object. Therfore I find I periodically miss this and accidently move an object, causing all kind of chaos in other assemblies using the same component. Is there a way to make select componet the default or sticky ?  

The Screenshot and My PC specs are below. Wiondow 10 home version I updated the graphic driver, and reinstall the DSM software.   Please help me.

Hi everyone, I'm currently working on designing a custom enclosure for an automotive diagnostic device. Given the rugged environments these devices operate in, I'm aiming to design an enclosure that is both durable and ergonomic. I'm using DesignSpark Mechanical for the CAD modeling and would appreciate any advice on: Material selection suitable for automotive environments, design considerations for heat dissipation, ensuring ease of assembly and maintenance. If anyone has gone through a similar project, your input would be greatly appreciated!  References: https://www.ancel.com/blogs/news/use-diagnostic-vehicle-code-reader https://www.allaboutcircuits.com/industry-articles/six-steps-for-designing-a-custom-3d-printed-electronics-enclosure/ https://www.youtube.com/watch?v=lAjmVMYUelA

The first pc shows my test jig/setup. I ran it for almost 2 weeks non-stop without any problems.   The next picture shows the electronic package installed—this is where I ran into a problem. The interrupt (the white wires) is getting falsely triggered. Telling me that it is getting triggered by noise coming off the other wires. What is strange when I attached my DVM to the interrupt test point, every started working properly and without any false interrupts!! This is telling me I need something to cancel out noise, like the DMV is doing.   The last picture is a screenshot of the PCB with the interrupt trace highlighted .    So this all boils down to a possible cap (or something else) to cancel out the noise. I am asking what type and value of cap would work/     Help

Quick question regarding lcensing for designspark. We currently use version 10 in labs across a university. Its licensed with a keylock.dat file - are we able to use the same license method if we were to go to version 12 please? this is for educational use if that makes a difference. 

I have an existing schematic symbol in the library. It is not one I created myself but something that was downloaded a few years ago for an LM3914. The text size for all the pins/pads (N1 to N18) is too large. I can find no way to change the size by selecting a pin/pad and clicking 'Properties'. The only way I can find to change the size is to delete the pad complely and create a new one. Having to do that for all 18 pins is a pain. Is there a way to do this?

Hey all, I’m working on a mechanical design project that involves developing a housing for a compact car diagnostic module. I’ve already prototyped the enclosure in DesignSpark Mechanical, but I’m running into challenges making sure the internal layout and external connectors align perfectly with actual diagnostic device requirements and workflows. To better understand how these devices function and how they are used in real-world scenarios, I’ve been digging through resources, which offers good insight into the tools and what technicians expect from them. My goal is to design an enclosure that not only fits all internal components snugly but also provides good thermal dissipation and allows for easy access to the OBD interface. I’m wondering:  Are there any best practices for mechanically designing around standardized automotive electronics (like OBD-II interfaces)? How do you approach tolerances and mounting in plastic vs metal enclosures in automotive environments? Any tips for syncing DesignSpark files with electronic component layout tools (e.g., from the electrical team)? Appreciate any insight or examples from folks who’ve worked on similar projects!

My HD crashed, and I restored a new HD from my backups. However, I can not get my library to load up. In the library, edited folders show my library, but the components tab does not show it. Clicking on the library icon, my library does show up. So I need help getting to my library.   

Hello DesignSpark forum community.Why is the surface dotted after using the Shell tool?I want to convert it into a solid body. How do I do that?Thank you. x

I have been creating schematics and PCB symbols and then combining them to form the component. I save them to "My Library". However, If I try to reach them after some time, they just disappear and are nowhere to be found. For exaple, a couple of hours ago I created a SSL file for Bridge Rectifier and carried it thru to the component. And now when I try to use the same file for a different shape PCB symbol, I cant find the schematic file that I had recently created and used. Am I missing out on something. It has happened many times now and was wondering if anybody else has encountered this situation.

２つのオブジェクトがあります。同じ直方体です。そのうち１つは角度を傾けています。こういう角度がズレた２つのオブジェクトを完全に一致させたいのですが、どうすれば可能でしょうか。ご存じでしたら教えてほしいです。 すみません。スケッチ平面→回転させたい分だけ円弧を描く→移動→アンカーポイント→パスに沿って移動→円弧を選択してB面からA面までマウスでドラッグ　という方法でできました。 マジで面倒すぎる。 こんな面倒なことしないと角度ズレの面どうしの整列って無理なのでしょうか。 有識者さん、プロフェッショナルな方、もっと簡単で確実な方法をご存じないでしょうか？
