route contains invalid angles

[rspargur77]

see screenshot. all i did was moved the run over a half inch and it just cannot rebuild it. nothing at all changed except the angled section should be slightly shorter and the vertical section slightly longer after having moved everything over the half inch. as you can see the angles are nothing weird. should be a 45 and a 90 like it was just a few minutes ago. why would it say it cant build a run of 3 straight sections of pipe with a 45 and a 90? anything i do seems to have an issue in this tube and pipe. im gettin ready to just model my piping im getting so frustrated. 

also how in the world do you constrain the routes? sometimes it will let me and other times it wont. like lets say i have 2 different areas that are nothing more than a pipe up 90 and then another straight section. i will have 1 i can constrain fine and then do the same constraints to the other (like included work axis and using parallel constraint) and it just wont do it says cannot create this constraint, no explanation as to why (which my goodness am i over that stuff, dont give me an error and just say cant do it, say whats wrong...like in my screenshot here it says route contains invalid angles...ok which ones would those be???? if it can recognize something is off why cant it just say what is off? i dont get it)

In your image you have written in the angles of 135 and 90,... have you verified those?  There is no forgiveness at all on route angles.  If they are off by so much as .0001 degrees, the route will fail.

Have you done any training or tutorials for T&P?  It really is not something to learn "on the fly" while trying to put out production designs.  It takes some time to master the basics.

no I haven't done training courses but I worked with it back in 2013-2014 and have used inventor on and off since I was in 9th grade and I'm 34 now. memories are vague with t&p and the more problems I have the more i think that at that time we used certain functions of tube and pipe but were mostly modeling the pipe and just using t&p on the threaded stuff. so that's why the routing stuff is giving me such a hard time. Most of my inventor experience is modeling, frame generator, and drawing creation, not tube and pipe so I'm having a hard time getting back up to speed quickly. I didn't have to do the setup work before (as far as setting up styles, title block setup, project files, etc) which is making things more difficult this time around. I'm solo, cant walk over to someone elses desk that is doing the same work and ask questions and bounce ideas off of them like I could in the past. This forum is my only place I can think of to try for help. I'm not in a position where I'm like ah I'll take a week and do some training and come back and try again. I'm also not trying anything difficult, have plenty of experience using the software, have some familiarity with tube and pipe, and have lots of piping experience. I'm just running 90s and straight pipe. nothing but threaded small stuff and 2-4in butt weld. that's it. don't need to know every in and out and be able to setup a million things in various ways. just need small bore threaded steel, 2-4in buttweld, and how to constrain the straight lines properly and i think i will be alright. have some faith in me! haha 

I just changed the dim precision and the 135 was indeed off by some absurdly small amount. now idk why that would have happened though. guess I gotta do some digging to see whats off.

appreciate the help I wont seem like a noob forever I hope.

We were all noobs at one point.  I think I'm lucky to have any hair on my head left after nearly twelve years of working with T&P.

First piece of advice I would give is: never use Auto Route.  That's just my opinion and preference, and some people love it.  I prefer to have complete control over my routes, using dimensions and constraints.  In my experience, perpendicular constraints work best, to work planes that may sometimes need to be added before you start sketching your route.  Remember that a pipe route is just a 3D sketch, but it is controlled by your Tube & Pipe Style rules.

I looked around for a video I made years ago demonstrating these constraints, but I cannot find it.  If I have time I will make a new one and share it here.

When you first use the route tool auto constrains are used but sometimes after dimensional moves of the routes the constraints will fail or fittings & pipe not populate. What you can do is use include geometry to bring in planes and use the constrain tool to constrain the routes against these geometry planes. For example ensuring the route stays parralel to other piping or planes.  You may need construction lines to stop rotation from happening also.  Here is a video that shows this process minute 12 has the include geometry and construction line use.
