3D view rotation challenge

Hi Oto,

This method seems pretty simple:

1. Create a planar shape from a Top orientation which bisects the mesh. 
2. With the Trim Surfaces command, trim the new surface with the red mesh 
3. Copy the new surface vertically 
4. Key in Rotate View Points, follow the prompts and snap to the appropriate points on the two copies of the new surface
5. Select the view to be rotated
6. Save the view
7. Repeat steps 4 - 6 three more times 

Here's a short video to illustrate the method:

This may work I have to check if this same approach could work with reality meshes. If trim will not work then I could project line on mesh and try to use that.. Only issue that for some reason it doesn't perfectly align with the outline.

does this help?

Thanks will take a look. This is more to show that to achieve it with standard tools it is challenge and should be made as standard tool but as developers are not end users it seems impossible to push it trough as all is WAD. Unfortunately Microstation still is CAD with CAD limitations and introducing 3D Reality mesh without reviewing actual workflow is what makes it hard to use. There are no standard views defined in Reality mesh so hard to align with mesh axis.

Sure. I think that there will always be particular requirements that will not be covered by the base app. I guess that the next best thing would be access to the underyling API that allows 'transparent' automation that does not require a high level of coding knowledge.

Let us know what you find.

Sheesh Oto, is this a trick challenge that you posted for a laugh at our expense?

The reason I ask, is because in the supplied DGN file, none of the base edges on the red mesh are parallel with their white line equivalent, thus you cannot use the red mesh for alignment AND have the vertical edges of the white shape (black lines in the images above) perfectly overlapping.

I believe I do have a working solution, but the incorrect view result I was getting made me investigate the source elements and find the discrepancies.

This is damn serious issue no laugh here when poor users are struggling with such challenge when I try to show how easy is to work with 3D data. Supplied DGN may not be ideal it is simplified version of what we have to deal when trying to align reality mesh with saved views. The difference could be related to Microstation trim tool results maybe the view was not orthogonal when I created the example. You are free to create your own but main idea is that mesh should not be parallel to any of design axis and to get view which is orthogonal. In perfect world buildings are built as designed in BIM, in real world no buildings are not straight.

Key-in: Dialog viewrotation is close to what is needed before fallback to VBA but with dynamic option and lock Z.

Challenge defeated!

Easy by cheating with VBA 
That is what I am trying to prove that standard tools require many operations to do it. Best is to avoid using real coordinates.

I saw no challenge rules stating otherwise...

It depends on what you define as the threshold for many. If you want a different alternative for consideration (using standard tools only), try this:

I mean, yes it works, but why take a longer, more painful route?

The more approaches the better.

There was such approach also:

I think that you could also use the Place Section Callout tool to generate a view that is aligned with the selected edge (vertices) whilst preserving the Z- direction.

The Place Section Callout tool works with Accudraw and you would place the Section Callout in a Top view.

After placing the Section Callout, you can use the Apply View button from the Menubar (Camera Position should be set).

Once placed, the SC can be moved and rotated to align with another face as needed using Accudraw + Snaps.

Its a classic example of how you can solve a problem in MicroStation in many different ways, each one formulated by different people with a different mindset on how to approach the challenge.
