"I'll take that approach then.  It will require checking a box and typing in two numbers for the exposure settings for each ArImage, which you can get from your reference drawing by using Image->Info in the menu."

Al hart /span>>

to meRichard

Your Revit order in November 2011 was for license RVLD4037L. What is not working in Revit for you?

Your AutoCAD License is XAMC04487K.

You can download the latest version of nXtRender for AutoCAD from:
this was a mail from al hart about my non working revit licence.
when I asked for an upgrade, they told me I had to pay for the new version.
This is not fun, the old one never worked. And I'm not sure if the new one works. You see, there is no support, they do not answer in the forum, and instead it was you. 
The other issue, the ADT materials, if there is not possible to seamless integrate NXT in ADT (ACA) then it is a must to have updated step by step tutorials, otherwise we are obliged to build averything by hand in plain acad 3d entities, and it's cumbersome to update everything
with best regards

well, I was happy with the autocad version of accurender, so I decided to buy even a revit licence, because our office is migrating to revit. It never worked, soI talked to them about that release . Nothing happened. then they came with a new release but I was supposed to pay for an upgrade ( which I'm quite unsure if it works) . Look silly if I have to pay for somthing that does not work, then pay again wout having any clue if the new one will work. that about revit. Generally is quite confusing right now about who's who and where the border goes between the acad and revit opperation. the people on the revit side you are pointing at, write at times even on the acacd forum. 

about acad ACA/ADT materials , I'll try the trick , but somehow it 's cumbersome if I have to go outside NXT in order to assign NXT materials to entities.

thank you for your mail anyhow. I greatly appreciate your work.

best regards

I bought nxt for revit and it never worked

a shame

moreover, I'm trying to get an answer about how to assigt nxt materials to autocad ADT entities, like windows, walls and the like. there are several poats about this issue here and there but I never managed to solve this enigma. So i'm left with two alternatives-to render in native revit, or to construct everithing with plain autocad entities and render with nxt, wich is time consuming.

How do I buy NXT to REVIT 2015?
I already have NXT to AutoCad.
I'm upgrading to REVIT and wish the NXT as surrender!

Hi Roy

I want to ask the following issues:
when I put the image in bitmap format bump material is skewed image after rendering. Guide me how to fix it.

Thank you very much!!!

In AR3 was how to render fonts in Windows ... You typed the letters of any Windows font, and apply the material and everything went right .... I could not do the same NXT .... Create letters I had to manually ... how to render the letters typed by AUTOCAD??

"Akin, I think you need to work on the glass material more. The IOR, Reflecction and Bitmap (if any) needs to be worked on. The material characteristic is key to realistic Illustration."

"Thanks Akin. The width of the opening is 55cm, rather marginal narrow for me. The camera angle is unfortunately too wide and distorting, as the room is absolutely tight."
