Fredo has solved this for me - I had a " : " in the sequence name, removed and it worked. Thanks!

@Rich-O-Brien ah yes I may have inadvertently caused confusion here. I get the first dialogue window where I set the aspect ratio, I set all that stuff and then hit 'generate video' - and that is the point at which nothing happens. It's the export progress window which fails to appear.

Also it is not a new .skp file. It is the same file which already works with the first animation sequence. I have then created the new animation sequence in the same .skp file but the export just doesn't happen. I can switch back to the first animation sequence settings afterwards and it works.

It's as if there is a bug in the software when more than one animation sequence exists within one .skp file. I've tried closing the file and re-starting SketchUp to no avail.

@Rich-O-Brien I'm not knowledgeable about Ruby Scripts but there are no messages in the console. There is no destination folder for the export yet as Animator creates and names a new folder as part of the export process upon hitting the 'generate video' button (that's unchangeable as far as I know). So Animator hasn't created the folder either - if that makes sense.

Hi I have been using this great extension for work this week. I have successfully created an animation and exported all the frames + MP4, with a 16:9 aspect ratio. No problems.

I have then tried to create a second animation which intended to use at a different aspect ratio (9:16), by adding different cameras and motions to suit the 'portrait' aspect ratio. But now when I try to 'generate video' - nothing happens. No exporter dialogue pops up.

If I go back to the original video set up - yes it still works.

Can anyone help?

it was drawn at 1:1.

If it's for a render like you show, it wouldn't have to be 1:1.

Yes I appreciate that - it's a habit i'm in drawing in millimetres for many years - I should totally set my units to metres and pretend they are MMs when using sketchup.

Lots of my work however is necessary at 1:1 for transferring to layout etc.

I still can't understand why the helix generates on a straight path of the same dimensions but not the curve (even at 100x scale)

The tiny face issue isn't actually about the faces, it is the spacial relationship of the vertices of the edges. When they get very close together Sketchup decides they are suppose to be in the same place and will just ignore them. An over simplification but basically the problem.
So while the helix is following a straight path the vertices are just far enough apart to work but as they go around the arc their spacial orientation changes moving them closer together causing them to fail.
It is very common with a simple follow me to have it work along a straight edge but then fail around a radius corner, Or a small sphere will end up with a hole in the top and bottom. In the sphere the edge lengths should be long enough for it to work but it is the distance the vertices are apart on the z axis that causes the problem.

Thanks, Box for the explanation - most appreciated & useful

The edge segments were still too short at that size. How will you use this helix now that you have it? I'm wondering if you even need it to be so small.

I was modelling a kitchen tap for CGI on our website, it was drawn at 1:1.

Does this look like what you want?

First I welded the edges so it's easier to select the entire path. Then I created a component which I copied. I scaled the copy up by a factor of 1000. In the UI for Helix Along Curve I entered the values as you showed (although I used the recommended value for Adherence).

The issue in your model is the tiny size as Box alluded to. Scaling up gets around that. There's no error in the extension.

Here's the file with the large copy. Select that copy and delete it. Then hit Zoom Extents to see the orignal one.

Brill, thanks Dave R for your help.

I still can't understand why the helix generates on a straight path of the same dimensions but not the curve (even at 100x scale) - but never mind!

Thanks again - everyone!

Scaled up the path, and also the radius dimensions to match.

Share the .skp file so we can see what you're working with.

What version of SketchUp? What operating system? Please complete your forum profile.

Thanks Dave have attached the .skp file and updated profile.

Looks like a tiny face issue, when it goes around the curve it is failing to form the tiny faces.
Scale up by 100 and try again.

Thanks for the reply, Box - still no joy
