positioning a render in an existing area

[baz88]

When architects design a new building which is going to be built amongst exisiting buildings how do you render a drawing like that? I'm a student and i have a building which would be built in the city centre on the river bank with many other buildings to either side of it. I want to render the building but i also want the exisiting buildings to be present in my render if that makes sense. How do architects do that? Do you have to draw the existing buildings yourself which would take a very long time in the centy centre with buildings everywhere.

In the picture attached say that pointy building is my design and the little buildings around it are existing, in a render how do i position my building to make it look like it's already been built?

This question might be better answered in the forum of whatever CAD software you are using but basically you would use photoshop are similar program to blend this image to a render of your building.

First you need to choose correct angle and position for rendering. Better to use existing photo in as a background for correct positioning. Render your building with alpha channel to simplify further post pro. It's good to use panoramic images from the site (if possible) as an environment for correct lighting and reflections. And finally some photoshop.
