Perspective between 3D model and background image on NXT autocad 2015

Hi, I would like to insert my 3D model on an image in background, obviously with the correct position, size and perspective lines.

Is there a method to move the 3D model to adapt it at the image in background?

At the moment i can only try to setting the position of my 3D model with the Autocad camera and launch the render to control if the position is correct, but it's impossible to find it. I must render my 3D model and put it in my image with Photoshop. Not a great result.

Look down here, the big machine is my 3D model but his position is not correct with the floor and all the structures.

Please can you help me?

Thank you

There are a couple of ways to do this--

In nXt the WalkAbout window allows you to insert and manipulate background images and your viewpoint independently.  You can either allow nXt to composite the image for you, or save the thing with a transparent background and composite it in Photoshop or equivalent.  You'll need to adjust the resolution (aspect ratio) of the view to match the photo.

AutoCAD also supports background images, so you could manipulate the model in AutoCAD.  The aspect ratio stuff is trickier here-- it's often easier to do this in paperspace where you can precisely control the aspect ratio of the viewport.

"Another good rendering. Those two photoshopped reading lights are not looking good though. They don't follow the perspective, the left one is higher than the right one. Also, they are supposed to be turned on (judging from the light on wall…"

"Great image as always. I would just blur the tree shadow on the lawn to match soft shadows on the building. Nice blending of cut-out greenery. Excellent job."

"Very nice rendering Chris! The only thing that distracts me is the fruit bowl. It's too evidently pasted in PS.  Another thing (nothing to do with rendering) is the microwave above the stove. I would rather expect a cooker hood there."

trim and extension command

On AutoCad 2021.The trim and extension command works funny. I initiate the command then click the cutting edge (press entre) then click the lines I need to trim or extend.Now I initiate the command and as soon as I click the object selected trims or extend.  How can I correct this, it is really affecting my work?See More
