symbol instance origin and rendering not aligned - please fix

[LarryO]

This occurs when Edit 3D is engaged in the drawing environment. (not from resources palette)

In this example the symbol's placement is 800mm along the X-Axis from the layer's origin. This is where the rendering of the object is occurring but the selections are at the symbol's internal origin that has been placed at the layer's origin. The symbol's origin needs to stay aligned with where it is placed relative to the layer origin and not at the layer origin. Or is it the other way around? The layer origin relative to the symbol's internal origin needs to be offset according to the instance's location.

When you are in Symbol Edit Mode 0,0,0 point is the insertion point of the symbol.

 

So draw or move you object so that the point you will normally want to use as the insertion point is at 0,0,0.

Any if you have symbols that are draw a distance from the 0,0,0 point, you will have to edit/move each instance back to where you want it (by moving the insertion point) if you edit the symbol definition and move the objects inside the definition.

I not sure know how to explain this better but I'll give it a try.

 

The object, a handrail bracket, is drawn upon the origin of the symbol. The round extrusion is actually centred on the symbol's origin.

In the layer environment an instance of this symbol is placed 800mm from the layer's origin.

When one goes to edit the symbol by choosing this instance and invoking Edit 3D the visual render of the object(s) remain at the instance's location relative to the layer's origin but the origin of the symbol moves to the layer's origin while in edit mode along with all the selection capabilities. So we see it where we expect relative to other objects on that layer but cannot select any of the components of the symbol where the render occurs. The application thinks they are placed the relative distance and direction that corresponds to the two origins having been aligned.

 

This behaviour doesn't occur when editing the symbol via the resource's palette because there is no need to render the layer's other objects in grey relative to a selected symbol instance. <edit> There are no other objects on the layer in this snapshot because I didn't want to clutter the view of where the selection highlighting is occurring. </edit>
