Origin plane issues

[Anonymous]

I've reset the default settings on my origin planes for both the IPT and IAM templates so that XY is the "ground" plane with Z pointing up. This is consistent with almost every other software out there and with the right hand rule commonly used by mathematicians, physicists, engineers, etc. Inventor seems to be the only oddball that points "Y" up. The reason I care about this is because I will export models out for use in Simulation or to share with other clients, who inevitably always end up with a sideways model.

The issue I have now is when I create a new part, despite redefining the "top" and "front" planes, I have to manually reorient the model every single time I create a part. The model automatically orbits to Y-up as the starting position... even thoughI can see on the view cube that "top" is pointed to the side instead of up. If I click "home", then it orbits the way I want it.

How can I stop this behavior? Why is "home" not the default position for new part creation?

SolidWorks and Creo use the same convention as Inventor.

Fair enough, but I've never used these programs. That's not really a helpful answer. My issue isn't really that the "y-up" is wrong, it's that Inventor can't seem to figure out how to work properly when Z is defined as up.

Hi schnautza,

You redefined it in the template correct?

Curtis, I'm not sure what you are alluding to with that post. I've read it and don't see anything that actually addresses the issue I listed.

I've successfully created the templates for both parts and assemblies with the top and front planes where I want them, but my issue is that the default orientation upon new part creation does not match the view that I saved as "home" and I have to rotate 90 degrees to get that (or click "home" first thing).

The template KNOWS which way I want home to be, but does not load that way.

Just to break this down a step at a time, if I create a new IPT file, I get my blank document and I see the view cube showing TOP, FRONT, RIGHT, all oriented as I'd expect them to be. I see the Origin indicator on the lower left with XY as the "bottom" plane and Z pointing up.

As soon as I hit "Start 2D sketch", the whole model orbits to where in the view cube I have the BACK where top used to be, TOP where front used to be, and RIGHT stays the same. XZ is now the horizontal plane and Y points up.

If I click "HOME" on the view cube, it reorients back to how it started. If I forget to do this step and start sketching on the planes as I see them, I end up with sideways parts.

All I'm wanting to know is how to stop the rotation of the model when I hit "Start 2D Sketch" (before selecting a sketch plane).

In Application Option, Sketch, Look at sketch plane on sketch creation and edit

Turn off both options.

Sorry, that's not the issue. I DO want to look at the sketch plane when selected. The issue I have is PRIOR to selecting the plane, the model rotates 90 degrees as soon as I click "create sketch" while having no plane selected in advance. And then, if I do select a plane after it's turned itself, the sketch plane is consequently rotated 90 degrees from where I'd like it to be.

Hi Alex,

I think you are talking about the ViewCube orientation. There is a way to reset it. Before you proceed, try using Standard (DIN).ipt template in Metric folder and see if it is the orientation you want.

Here is how you reset the ViewCube in a template file or any existing iam or ipt file.

1) Open the file or template file.

2) Click on ViewCube so that you are looking at Z -> up and X -> right.

3) Click on the small downward arrow under ViewCube -> Set Current View As -> Front.

4) Click on a corner of the ViewCube so that you see Top, Right, and Front nicely oriented in Isoview.

5) Click on the small downward arrow under ViewCube -> Set Current View As Home -> Fit to View.

6) Save.

Now, you will have Z points up. Does it work for you?

Many thanks!

No, this is not the issue. Please read my previous posts to see that the issue is the rotation of the model after hitting "create sketch" prior to selecting a sketch plane. The templates are set up just fine and top and front are defined as I like them, but the model rotates away from the home position as soon as I click "start new sketch".

Currently my preferred settings are

Front view plane: XZ(-Y)

Top view plane: XY (+Z)

Home is where I see "TOP, FRONT, RIGHT" on the view cube.

ahhh, indeed I did not understand this to be the issue, see this link as I think the issue you are asking about was discussed there:

https://forums.autodesk.com/t5/inventor-forum/viewcube-orientation-on-document-create-application-options/td-p/6579168

Edit:

And just to clarify, I don't think there is a solution to this, or a way to set the orientation of the "initial" view when you start the a sketch and the planes are displayed, but @johnsonshiue might be able to confirm this one way or the other

and below is a video of the issue (as I understand it)

I hope this helps.

Hi Alex,

Then, it is about the invisible origin planes popping up on creating the sketch. Please take a look at the following thread (the last reply to the thread). There is no option to control the behavior but there is a way to suppress the behavior.

Curtis, your video clip illustrates the problem perfectly. 

Johnson, I'm not sure what origin plane visibility has to do with this - that linked post had nothing about the problem I am trying to address.

I don't want any planes with visibilty turned on, I can easily select the plane I want in the browser without turning them on.

[johnsonshiue]

Hi Alex,

After watching the video, I am certain this is about origin planes visibility. Try this. Start a new part. Then make just one of the origin planes visible. Now try creating a 2D sketch. does the view rotate?

Many thanks!

[Anonymous]

Indeed, if I turn one plane visibility on, it prevents rotation. 

So, without turning any planes on (that makes models get really sloppy really quickly), how do I fix this? There has to be a way to disable this behavior.

[blessing86]

I'm trying to fix the same issue. Did you get a solution?

[Anonymous]

Unfortunately, no. I've just had to train myself to always check the orientation of my sketch before beginning.

[johnsonshiue]

Hi Guys,

Did you try the proposed solution discussed previously? The auto-rotate behavior will be suppressed whenever there is visible geometry to pick. What you can do is to pre-select an origin plane. Or, you can make all origin planes visible in the template before you start a new iam or ipt file.

Many thanks!

It's extremely undesirable to me to have to toggle on visibility of an origin plane prior to making my first sketch. This is not an acceptable "solution" in my opinion, as it introduces another step to fix something that should not be a problem in the first place.

[johnsonshiue]

Hi! I am not saying it is a solution but that is the best I can offer. I know the behavior is annoying as I have explained it before. You can also open the template file and make the origin planes visible. Then you don't have to toggle the planes visibility. You do want to see the origin planes first, right?

Many thanks!
