Render preview showing page limits

[c_d_wood]

Hi all,

I have an issue with rendering, in that I normally have to render something 5 or 6 times to get the zoom level and model position correct on the rendered image, since I have no way of seeing how large the model will be on the render until it is complete. Is there a way to preview the size of the render to get the zoom level correct (i.e. not simply doing an in-canvas render, which doesn't show the image size)?

I've seen some solutions which talk about using "Named Views" - I use these but they still require multiple renders when setting them up in order to get the zoom and angle correct. Once set up they are fine.. until I change the render resolution and then I have to start again.

I am a former solidworks user, and the render preview showed the extent of the whole rendered image, allowing the model to be positioned correctly and the zoom level set prior to committing to a full render. Does a similar functionality exist in Fusion 360?

Thanks in advance,

Woody

Are you talking about the local Render, in the Render Workspace?  In-Canvas Render on my system yields an image reflecting EXACTLY what was viewable on my screen- this is, the same aspect ratio.     Is that the case for you?

Hiya, thank you for the quick response. No that's not quite what I meant - my in-canvas render also replicates exactly what I see on screen. My problem is that when I submit the job for a cloud render, I have no idea how big my design will be on the rendered image. I suspect it is because of the different aspect ratios of my screen and the preset render I use, but it would be much easier if I could view a preview of the actual render to get the view correct.

For example, this is what the view is like on my screen:

This is what I can see in the software....

Whereas this is what the final render looks like:

This is what the render looks like (3300 x 2550 res)

So on screen almost all the corners of the cubes are clipped, whereas the final render has loads of white (i.e. wasted) space around it. In order to get the cubes into the final render, I first had to randomly alter their position and zoom level, rendering in between each view change to see what the final image looks like. Some failed attempts:

  

Since I don't know how to preview the final rendered image, it's a trial-and-error situation and makes everything a lot slower than required. I am happy to be told I am being stupid and missing something obvious, but I just can't see it yet!

Hi again,

I just thought I would upload another crazy example since I don't seem to be getting any responses. The first image below is a model on my PC screen, and the second is the first attempt at a render (that I stopped from completing). It's really difficult to predict how much which space there is going to be and therefore how much to zoom in by without a proper preview of the final render. Surely this functionality exists...

As far as I can see, there is no indication that my model will be so tiny on the final render, apart from the model dimensions themselves. However, even should I calculate the model proportions with respect to the rendered image size, how should I then use this to zoom sufficiently and select the correct viewing angle?

Hi, I'm having this problem too. Did you solve this ??

tks

No I didn't solve it unfortunately. I gave up waiting and just struggled on! The only thing I can think of is that, if you set the render size to the same resolution as your monnitor, you may have a better chance of seeing an accurate estimation of the render onscreen. Seems a silly issue, I can imagine it's just you and I encountering this problem!

Just to keep the thread alive in the vein hope of a solution... here is a recent render:

rendered imageHowever, here we see the position I had to place the sphere onscreen in order to achieve a render in which the ball filled most of the available space:

screen captureHardly a good representation! (You can see a previous render attempt in the gallery which shows excessive white space...). Nice to see the 'Fusion 360 is turning 6 years old' - perhaps a render preview would be a good way to celebrate?

Same problem...

the question is simple: how to see a preview of the final image render on your screen before rendering... 

else we just have to rerender as long as the position isn't good.

Looking at the images you posted in message 4, it appears you don't have the aspect ratio for the scene settings set the same as the aspect ratio for render.  The in-canvas render, and the actual cloud render will never match up if these aren't the same.

Such an obvious thing, and yet we all missed it. Works beautifully, thank you!
