Vectorial Shadows in ELevation - AC10

[Anonymous]

Hi Guys,

Just a quick questions on Vectorial Shadows in elevation.

Say I have two buildings, A and B.

Building A is the proposed new building.

Building B is the existing neighboring building.

How can I see the vectorial over-shadowing effects of Building A on Building B in elevation?

My problem is that the section marker only shows what is in front of it. Thus if I move it in front of building B, it only shows the shadow effects of building B on itself without regards to the new building A.

But if I move the section marker in front of building A, then it visually blocks out building B.

Any help would be greatly appreciated.

Cheers,

A screen image / Plan would help.

Sorry guys knew I forgot something 😉

Anyhow here is the attached JPEG.

I want to show the effects of the shadowing due to building A on the elevation of building B.

Cheers,

Now I understand.

But I still don't have an answer for you, sorry. Can't think how you would do that in an elevation view. Even copying / pasting from a 3D view would be hard to set up 'cos you have to set up a parallel view, but from between the two buildings, and I'm not sure how you'd do that and still have building A considered but not shown.

please do a search....there is a trick with glass/transparency i think..

Thanks for the replies and links guys

But I'm still a little confused about the work around process in using glass.

map adjoining property with glass material and turn Transparency in Shading ON in 3D window settings. Put section behind the adjoining property (so you will see the elevation of your building through). Then unlink the section and delete all undesired lines.

So... I take it that I should change all of the material of building A to glass and then put the section line behind it ?

But if I do that, even if the material is glass, in section it'll just become opaque....

I guess it'll work if you render a sectional view in the 3D engine although you can't exactly render at a particular scale.

Hmmmmm....

Turn Transparency ON, but this will of course affect Building B also. And won't you still get outlines of Building A elements if the section line is beyond it?

Okay here's what i did:

Converted the existing building into glass. I think the best way is to save the entire model as a gsm. so then you can change all the material in one go.

It was kinda tricky because you can't save the entire model as a single gsm and I had to do it individually for each storey and then group them together.
