Re-Orientate Origin Views

[Anonymous]

Why are the XYZ planes orientated different than AutoCAD, Revit or the common sense and universally accepted orientation where XY is horizontal, ie Top View, and the Z axis is vertical, where XZ plane is front, with Y+ away from the viewer. The default in Inventor is opposite and causes Import/Export orientation problems. I've gone and changed the orientations already in the Options page, but its still cumbersome. When I choose a new sketch on an origin plane, like XZ, and it auto rotates me to the Back view to start sketching, when really I still want to sketch on XZ, but from the front. So it adds an extra step to rotate to the front.

The Inventor orientation is the same as the universally accepted standard. The X-Y plane is used for every 2D graph/vector diagram where X is horizontal and Y is vertical. Z is added when depth is introduced. 

Perhaps a better option would be the ability to rotate imports to the correct orientation.

That's not entirely correct though. Have all the Defaults set in Inventor and start a part and new sketch. XY Plane is the Front View, the XZ- Plane is the Top view. Now open AutoCAD, the Top view is the XY Plane, and the XZ plane is the front.

How AutoCAD has it is the way we've all been taught since school, is that both the X and Y axis are horizontal, the Z axis is vertical, jumping out of the page at you when viewing it from the top. Go to any CNC machine and tell me what the XYZ Axis are. The X and Y are the Horizontal, and the Z axis is the vertical. The tool follows the Z axis up and down, the table moves horizontal along the X and Y.

Now import an Inventor part or assembly that's been built to the Inventor default planes and views, into any other program, AutoCAD, Revit, Navisworks etc. and your Front becomes Top, and Bottom becomes Front. 

Inventor should change its defaults to the accepted standard.

Hello,

I am bring this back up, as I have a new Autodesk account.

Below are images of what the differences are, for clarity.

ACAD Default Top View, XY+ Plane (correct IMO) Inventor Default Top View, X+Z- Plane.

ACAD Home/ISO View, Front is XZ+ Plane. Inventor ISO View, Front is XY+ Plane.

I have had issue with this ever since I started using inventor at release 11. I have always reset my viewcube 'Top' view to the XY plane on all my templates which helps us get our heads around the 3D models the way we've all been taught, X-Y horizontal and Z Vertical. There are issues still with this but they are less of a bother than Z not being vertical so we overlook those. If I had to bet on the reasons for inventor being this way, it would appear that the initial view when creating a new sketch it was deemed important to only show the positive sides of the workplanes and when you do this it shows Y in an up direction. The from there the sketch constrasints for horizontal and vertical have been mapped to Y being vertical.

Anyway I would welcome the option to choose Z as vertical axis and see the negative side of the X-Z workplane on initial sketch creation.

Hello all again,

I'm hoping some activity can get this post to have more views.

Anyway, I've found some more supporting evidence that AutoCAD and Inventor views are different, and Inventor should change to the AutoCAD style.

Shown below is the AutoCAD Mechanical Options page, where we can change the default Front View from the XZ, to the Inventor Style XY.

Hello,
there is a way around this, in inventor when you open a new piece you have to do this from the template folder. You can open this from the template folder and reorient the top view so that it matches the standard xyz coordinates. save this template with the other default templates. Now when you start a new piece you can use the good template that you have already reoriented. When you now transfer stp files to Autocad, they are in the same orientation as the standard. I use this method to transfer piping from plant 3D to inventor models and vice versa

above the template with z value to the top used to create the figure, then exported to dwg and opened in autocad, the figure is according to the correct coordinates
