Yes I have, with no difference.

Using classes is another option but the designer who is doing this decided to put different components (mechanical CAD) for a telescope design on different layers. He now wants to align them to each other. All of the layers do have the same scale and same view orientation (using Align Layer Views) but in any view other than Plan it is not possible to snap to 3D objects in other layers. The temporary work around is to place a 3D locus on the snap position on the reference object and then copy this locus and paste it in place on the working layer.

I already tried this. I should also mention that I have other, much more complex models which render and rotate without reverting to wireframe.

I have created two very simple files. One is a simple box on a single layer. When render with OpenGL and rotate the model the OpenGL rendering is retained. In the second file I have two layers. On each layer I create a simple box. I then add a third model layer and link to the other two layers. In this file the OpenGL rendered model is never retained when I rotate even though I have set retain OpneGL model to always. I am running VW 11.0.1 on a Mac Powerbook 1.5GHZ with 1.5 GB ram on OSX 10.3.6.

I know that working in 2D it is possible to snap between objects in different layers. This does not appear to be possible in 3D even if the layers are all the same scale and they are aligned. What is the recommended method for aligning objects in different layers.
