I'm a little confused. After reading the documentation for IV 2013, I'm not sure if it's possible to create a midplane between parallel faces of two different parts or not. I've tried using the workplane buttons in both the 3D Model and the Assembly tabs with no joy.
Can someone please clarify?
You would need to use a parameter
If the one plane is constrained to another work plane, you should be able to use the paramter ID / 2 as your mid distane.
Work-Plane 2 is contrained from Work-Plane 1 by contraint "d26". You should then be able to us "d26/2" for your distance when you create your mid Work-Plane
Inventor 2013 does not provide midplane constraint. Workaround is to create Mate assy constraint between two planar faces. Then use half of constraint modifier(distance) as a parameter when creating new work plane defined by perpedicular distance form a plane.
Hope this helps.
Correction, I should have used "Offset" rather than constrained, but the same parameter methodology will work.
I know this is an old post, but I was trying to create a midplane at the assy level and could not do it.
Robert, you say that this is not supported in Inventor 2013. You say that like it is supported in a different version. I just tried it in 2014 and it does not work in it either (unless I am missing something). I was doing something similar to what you suggested, but that requires the offset to be manually adjusted if something changes. I wan the midplane to be stay in the middle then things move in the assy.
There is an "accepted" IdeaStation thread that addresses this. Hopefully, this will be addressed in a soon-to-be-released version.
I believe he wanted it to mean that it was not supported in 2013, but may be in future versions precisely because of the Idea Station thread you mentioned.
The method he was metioning goes like this:
Make a parameter to reflect the distance apart you want your parts to be, say 'width' or something like that.
When you constrain those parts together, use an offset contraint and when you type in a value for the distance of offset, type in the parameter name you created.
Now make an offset plane from one of the faces you contrained earlier, and make the offset equal to half the distance. You can use parameter names in equations, so you can just type width/2 and the plane will always remain halfway between those two parts.
You have to remember to update the parameter and not the contraint if you want to change the distance between them though.
Hope this helps. See the attachment for more clarification.
Yes, I totally get how he was saying to do it. Its just that I did not want to have to use parameters (I would forget to change it later). The way that I did it was to use an assembly sketch with a line between the two surfaces. I put a point in the middle of the line and dimensioned to the point. Next, I created a plane and offset the plane with the driven parameter to the center point.
Now, when the parts move, the mid plane "automatically" adjust to be between them. See my video here.
Ah, that's neat! I'll have to remember to do that the next time I need this. I apoligize if I sounded condescending or anything. I agree with you that this kind of workaround is a bit silly, and I really hope that Autodesk would add this feature because I would use it every day.
