AC3D – beginner tutorial – creating, moving, resizing. by acorvale. Ac3D Aircraft Modeling Tutorials: Cabin Window Frame. by Narendran. I just got AC3D, hoping to expand my ability of 3D modeling. I was wondering if some one could point out a few good tutorials to start learning. Hi guys, I got several questions about the airport design in AC3D. Here is my first video tutorial aerial image background in AC3D Hope you.

The “reference point” is just an arbitrary location on your background image. However, it can also create issues with selecting what you intend to select in the 3D view, as you’ll see at the end of my video when I was trying to correct the surface normals As I say a request for the list.

This certainly isn’t that simple and it creates a really ugly mesh if you have used curves and splines to define your runway like I did, but Aerofly doesn’t seem to mind about xc3d mesh ugliness because it’s only using this to determine where the non-runway terrain ends as far as I can tell. As you can see the runway is as per the background image, image sourced from fset but when i put it in the sim it is not overlaid under the original runway, see pictures a few posts up.

The x-axis in ac3d points to the north in aerofly, therefore you ttutorial rotate it before exporting. I tried that but got stuck trying to manipulate that outer runway mesh.

Can you do another video tutorial showing a more advanced form of runway mesh cutout? Yep, you’re correct on what I meant by “innermost vertices. Even if you’re really yutorial with your rotations when modeling the airport, you might end up with the reference point shifted to a different location after the final rotation to align your airport so that North points to the right.

They have also been added to our wiki to make things easier. This is a bit confusing, but the x-axis in AC3D which points toward the right of tutoriak image corresponds to North. Clayton, if you can get your files to me somehow your.

You will have problems when you export and then convert the. I’ll have some fun now adding objects to my airports. So if you have several contiguous areas like I did, you’ll have to repeat this operation on all of them. Is it 90 degrees out, or is it out by the approximate amount you rotated for mesh alignment? I tried the knife and also using Boolean combinations to do the cutting, but never got a result that I was perfectly happy with.


Here’s a picture of my mesh which may help explain the above. I couldn’t find out any more about using the knife or vertex picking. If it’s hard to see the pink lines, tutorisl the the settings menu, to the graphics tab, and then change “Size of display normals” to a higher value, e.

And here are the already-converted files that you can load directly into Aerofly if you want: The following tutorials are under preparation. Here is the folder you sent me, with the corrected files inside: The pink lines those are the normals should come ‘up’ from your runway, not point below it.

In Rodeo’s video tutorial he explained a great way to do all of this so you don’t actually have to understand exactly what the reference point’s meaning really is, and that works well if you’re careful not to move your objects away from that original reference point. Thanks qwerty42 – this is great stuff and very much appreciated. It better fits to the Bermuda Dunes series of the following videos and it shows an extremely easy way for handling reference points and coordinates.

It’s not as good as the stuff Rodeo makes and there’s no audio, but hopefully it helps: So if you already have it named and grouped like I did, make sure to select the keeper first before doing the merge. That looks good so far. Here’s a screenshot of how it looks right now I only geoconverted a small area around it: I hope that wasn’t too confusing.

Also am I limited to the resolution of the mesh when it comes to aligning it with the background image? I also tried using the Boolean operations thtorial the knife command after extruding the cutting surfaces, as well as the fill holes command, and none of them could quite make this work without other issues. This is because it rotates about the geometric center of the shapes you’re rotating. Futorial must have had it confused with something I read in a different tutorial.

If you don’t have it enabled when grabbing all your runway vertices, it might not select all of them if they’re packed close together like mine. I know the sunken ground problem. I think this is all of them. You will end up with a triangular surface mesh that connects the all the vertices, meaning you will need to then do a shift-select to grab all the ones where your runway is and delete them to create the cutout.


Rodeo – You’re a legend, thanks for this! Maybe I’ll make a video to describe this too. Can i now add 3d objects to this and export tgi files as explained in the A3CD download on making your own airport? In Ihrem Webbrowser ist JavaScript deaktiviert. I can explain better in a day or two when I have more time, but what I finally got to work was to cut out an area of my ‘outside’ mesh around the runway.

I’m trying to determine what the variance is. I’m not sure what you mean by innermost vertices though? It needs to be in the troubleshooting list this one. Thanks for all you work on these tutorials.

As well as the criss-cross runway problem I just made a turorial runway on a different airfield but found that the 45m mesh I created to match the runway width was a poor fit lengthwise, so either I chop off a chunk beyond the runway or I have some background runway markings emerging beyond my created runway. Or is the recommended approach to take the kdwh example, cut out the existing background image, load in a new one as you expkain here and try to tutoria and stretch the kdwh objects for use in your own airport?

You have tutorixl major orientation problem at some point. Note that I made a mistake at the very beginning — I still had “select through” enabled, and when I intended to select the surface under my mouse cursor, it for some reason selected a surface off-screen and I didn’t notice. As for making mistakes in video tutorials I think they are very tuttorial, as the first timer is going to make the same ones as well as many more!
