Need help with a small parametric problem

234 Views, 7 Replies

Hi All,

 

I'm trying to model a stanchion that has it's angle parameter linked to a plane. I've got most things to work really nicely but for some reason when I try to set the angle past 33 degrees I get an error. The angle is supposed to go up to 45 degrees.

 

  I've attached the part and was wondering if somebody could have a look at the error message I'm getting and tell me what I'm doing wrong. When you open the part just look for the plane that is named stair angle in the browser and increase the angle beyond 33 degrees to get the error message.

 

Any help would be gratefully appreciated.

hi quad,

  when you see problems like this, one thing you can do to find out what is going wrong is you can drag the 'end of part' icon up and down to find your point of failure like i have shown in the snapshot.

best regards,

Hi quadratec, Whenever I get update issues like this I will try a different approach something like the attached (made up shape – not yours), using planes with one driving the required angle. Hope this helps Cheers Mark Inventor 2013

Hey thanks for that awesome tip Mark. I'll have a look at that area of the part.

 

What do you use to do your illustration with? They look good.

I don't know why it failed, but I was able to fix it:

 

- Roll the EOP marker up over Extrusion 10.

- Right-click on StairAngle and change to 60deg.

- Roll the EOP marker below Extrusion 10 and accept the error.

- Edit Sketch 20 and constrain the center of the 40 diameter circle.

- Exit the sketch.

- Roll down the EOP marker to the bottom.

 

Should work fine up to 63 degrees, afterwhich the model fails due to sketch failure at the angle cut on the bottom of the pipe - Extrusion 5, I think.

well done graeme, that roll up and down of EOP helps with challenges like that, especially when working on someone elses model.

 

 

(ps- to also answer your other question from the other day, see techsmith website http://www.techsmith.com/snagit.html for the snagit software. (screen capture + lots more if you need it) i find that it is a great tool for engineers and designers to communicate with each other).

best regards,

How did you do that with the snipping tool? I use it for all of my captures but I do my editing in MS Paint. I'm only aware of the pen and highlighter tools for editing in the snipping tool.

 

Edit: Nevermind, I got the Marks confused.
