Difference between ASideFace and BaseFace of a FlatPattern

[dominiek_vanwest]

Hi everyone,

I would like to know what the exact difference is between ASideFace and BaseFace of a flat pattern.

From the Autodesk Help I get this:

ASideFace: Read-only property that returns the ASideFaceDefinition from the folded model that was used to create the flat pattern.

BaseFace: Property that returns the base face from the folded model that was used to create the flat pattern.

But I still don't understand the exact difference.

The reason I'm asking is that I want to check the appearance of the flat pattern face to see if that has a particular appearance or not (to make sure our flat patterns have the correct orientation).

But I want to know which of the 2 I have to use to be correct. Now they both return the same appearance, the correct one. But I want to make sure that I use the correct property. Is there a situation where the properties can return a different value?

Thanks in advance!

I don't know how it is implemented internally, but in my opinion the difference and behavior is as follows

1. flatPattern.ASideFace - Is a complex object introduced in Inv 2016 for better control of flat pattern creation.
2. flatPattern.ASideFace.ASideFace - Returns the face from folded model. In my opinion it returns the same object as flatPattern.BaseFace
3. flatPattern.BaseFace - It is a property introduced in Inv 2008. Now it is present for backward compatibility or as a shortcut for flatPattern.ASideFace.ASideFace

Hi @Michael.Navara 

I’ve been trying to gain a better understanding of the object model, and as you seem to possess considerable expertise, I was wondering if you could clarify a couple of points for me.

First, could you explain what exactly flatpattern.Topface is and why it isn’t the same plane as flatpattern.asideface.asideface? I’ve tested this and noticed that neither Topface nor Bottomface ever corresponds to asideface.

In addition, there is a collection of planes called flatpattern.asideface.Faces. Does this collection contain all the planes from the folded model that correspond to asideface on the flat pattern?

Many thanks in advance for your assistance. Any insights you can provide would be greatly appreciated.
