Hello @80944291
The RF/FF/RTJ facings are just text that is filled in in the facing property of any flanged part in the catalog.
You can modify and edit your catalog to make new parts with different facing values.

To set up a groove and tongue connection you will need to also adapt your project settings (joint setup). This is all a bit too elaborate to explain in a single forum post. Did you have any training or do you have a software reseller in your region that can help you?
I wrote an article about the groove / tongue setup in Plant 3D a while ago. It's in dutch, but any online translate app can help you get the essence.
for some reason the autodesk forums keep changing the URL, there is a series of numbers in the URL and the forum thinks it's a phone number so they get changed to xxx-xxxxxxxxxxxx. Just give me a PM (in English / Dutch / French ) if you want the link to the article.
1、通过PLANTENDCODES新建两种连接类型M,FM。注意是连接类型不是密封面型式。
2、设置凸法兰的端点型式为M/BV,密封面为MFM;凹法兰的端点型式为FM/BV,密封面为MFM;螺栓垫片的密封面为MFM;
3、设置简单连接,M对FM,必需匹配项为直径、密封面、压力等级,紧固件为垫圈和螺栓组;
4、设置两个组合式连接。凹面法兰连接端点1选FM,法兰的端点类型选M;凸面法兰的端点1选M,法兰端点类型选FM;
这样就可以实现凹凸面的匹配连接了。
注:仅通过密封面是无法实现凹凸面的匹配连接的。

参照我的简单连接,端点1是M,端点2是FM,你不能把M和FM都放到端点1或2里。不然就承认了M与M也可以连接。 在组合式连接里,端点1为FM,但是在法兰端点里,需要适配M,你填FM就不对。具体的你再检查一下设置。按照我这个设置M和M,FM和FM是不能生成垫片的。
