Rumble Posted March 26, 2021 Share Posted March 26, 2021 Hi, Is there a way to add cut shadows to floorplans whilst keeping the general look like a Top/Plan view? Below is the sort of thing I would like to achieve. I have searched to see if there is a similar topic but can't find what I'm looking for. I have tried playing with the clip cube but I loose the simple line drawing with door swings, etc. I'm new to the forum so apologies if I've posted in the wrong place or any other mistakes. Thanks.

Vectorworks, Inc Employee Dave Donley Posted March 26, 2021 Vectorworks, Inc Employee Share Posted March 26, 2021 Hello @Rumble For these kinds of shadows you can render with OpenGL with shadows on, textures and colors off, and ambient light set to a high value (80% or so). That should give you the gray shadows. The other parts could be another viewport overlaid over the OpenGL rendering I believe. 1 Quote Link to comment
Rumble Posted March 26, 2021 Author Share Posted March 26, 2021 Thanks @Dave Donley. That was one of my thoughts but the overlaid viewport has a solid white fill or background to all, so it masks the OpenGL viewport, and vice-versa. I might be missing something simple. Quote Link to comment
Jesse Cogswell Posted March 26, 2021 Share Posted March 26, 2021 @Rumble Make sure that the overlay viewport is set to Fill: None in the attributes pane. If you have a solid fill for your slab that occludes the other viewport, you can do a combination of toggling off layers (if the slab is on its own layer), or use class overrides in the viewport to make sure that they also draw with no fill (assuming that they have a dedicated class and object attributes are set by class). 1 Quote Link to comment
AlanW Posted March 26, 2021 Share Posted March 26, 2021 (edited) @RumbleHi i use a Renderworks Style i created to produce sun studies for shadow diagrams, it only creates a shadow and no building. . Use 2 viewports on top of one another and important to have the alpha channel unticked. Also doors open in 3d or not cast shadows. See attached. HTH PS If you turn off the doors and glass the sun show through to beyond. Shadows_v2020.vwx Shadows.vwx Edited March 26, 2021 by AlanW 1 Quote Link to comment
station Posted March 28, 2021 Share Posted March 28, 2021 this is just simple plan viewport (wireframe) where I enabled shadows on the walls in the layers. You can adjust the angles, blur, colour and offset. It doesn't affect crispness of the linework 1 Quote Link to comment
zoomer Posted March 28, 2021 Share Posted March 28, 2021 We had a similar Discussion on the german forum where I also recommended VWs new drop shadows .... The problem is these are only blurred versions of Object's 2D appearance, without reacting to Object's volume in Z. Like in your example, that makes Objects (Walls, Buildings, ...) look like they are floating at a certain distance above a surface. While the actual purpose of using Shadows in a 2D Drawing is to show Volume, Height and that the Object is grounded. 2 Quote Link to comment
station Posted March 28, 2021 Share Posted March 28, 2021 true and the examples blur on both sides of the wall (which can be finetuned and height can probably be better approximated - it is just a fast way). I like Alan W's approach and works well for siteplans Quote Link to comment
Rumble Posted March 30, 2021 Author Share Posted March 30, 2021 Thanks for all the suggestions. Good to know what is and isn't possible in VW. The explanations of the 2 viewports helped, particularly @AlanW screenshots and vwx. files to be able to see the settings I was missing. Thanks all. Quote Link to comment
