Hi Rdavies, here's a few options for you...

1) create 3 x 3d views - orient each to plan view, make sure that your true north is correct (as opposed to project north), set the shadow setting on each view to your required time... dump on the sheets and beg council for a speedy response!

2) if you want the 3 shadows overlayed, i think it would be easiest to set your shadow info as required, then use filled regions to trace around the outlines of the shadows - use 3 different fill patterns to show the different times.. for me this is a bit more work and nowhere near as good as option 1 as it's just linework and won't update with design changes...again dump on the sheets and beg council for a speedy response!

3) Set your 3d view to plan view the building, render the scene at each required time of day, then export each of the renders, then import the images into your sheets... and beg council for a speedy response! This is still not as good as option 1 in my opinion - but horses for courses...finally BEG council....

I hope this is clear enough - i've only had 1 coffee today! did i mention to beg your council?

Thanks for that. I had a ply around with a simple diagram and the render options seems to work ok.

 To create each new 3-D image, are you referring to the 'New Camera' function?

I think you're referring to option 3, in which case you need to render a 3d view of the building, as follows:

1. go to your 3d view in the project browser and orientate it to a plan view of the building

2. set your shadow settings to the time of day required

3. render the scene - ensuring you use the correct render date/time etc. in the rendering dialogue

4. export the finished render and name it according the date/time

5. repeat for each time of day... and then import the images onto a sheet using file>import>image

again i think this is not as good as the first option i mentioned regarding creating 3 x 3d views, which involves duplicating the original 3d view and naming each for their respective date/time - you then orientate each to your required date/time and then dump those view onto a sheet..

Thanks again.

I've had issues with option 1, which was the most logical way I envisioned doing this task.

I have followed the steps exactly as you have written.

i.e. Make duplicate of the original drawing, rename it, change the sun settings to what I need.

But, each time I do that, the sun settings on the original drawing change to match the duplicated page. I've tried this with normal plan views and 3-D views.
