Hello,

This is my first post to the Podium forum, so please forgive me if I commit any faux pas.

Though it works on simpler models, when using the Podium Section Tool on this particular model, the process goes to making a copy and then I get a Bug Splat. In the information bar at the bottom while the section tool is processing, it appears that the section tool completes (or nearly does) but stops short of opening the new, cut file. The resulting copied file has no changes from my original file.

I'm using this on Windows 10. PC specs are:
Dell Precision Tower 5810
CPU Xeon E5-1620 v3 @3.5GHz
32GB RAM
NVIDIA Quadro K2200 2GB

I am using Sketchup Pro 2016. I do not have any other plugins installed aside from Podium. My version of Podium is 2.5.519.

The model has been purged, and the file size is 32 mb.

Edit: Pictured below to show model complexity.

Either your model is too complex (file size isn't necessarily a good indicator, because if it contains lots of duplicated components, the geometry count could bear no relation to the file size), or there is something in it which is causing a problem.

Do you have any geometry imported from the 3d warehouse?

Have you run Podium tools to see if there are any errors?

I do have geometry imported from the 3D warehouse. Podium tools only has 1 alert: 1 no extension texture.

Okay - first thing to do is fix the errors.

I removed all of my 3dWarehouse objects, and found the problematic texture and resolved it. Still getting a bug splat. Maybe I will just have to intersect a plane and delete things myself.

That's actually how the plugin works [smile]

We have tested it with some pretty complex models and most of the time it's fine. Your machine seems to be easily powerful enough to deal with the creation of a section for this model.
I wonder if there is something about the location of the section plane?

Is it possible to move it a short distance in one direction or another and try?

We don't get issues like this very often, so it would be good to try and find the cause.

Actually, there is a bug in sections and it's been identified by Nick a few months ago.  It's difficult to explain and even to be completely sure, but the bug seems to occur when you have some imported (like from AutoCAD)and/ or hidden geometry  One way to identify the geometry is to turn hidden geometry on and remove hidden geometry.
Also, an example would be a floor plan that was imported from AutoCAD and then used as a basis to create the 3D SketchUp model.  If you explode the imported 2D floor plan or remove it, the crash is solved.
I'm not sure if this will resolve your problem.  We are trying to narrow why the crash occurs.  If you don't mind uploading your model here:
http://www.suplugins.com/podium/support.php (and email support@cadalog-inc.com), it would probably help a lot.

AS Dave said. This is a bug with SU 2016 only, if you still have SU 2015 with section it should not crash except if there some major issue. Its very hard to identify the specific recurrent cause. Last model I analysed was a combinations of 2 different elements. It crashed only when the 2 elements were there - very hard to track down.

Hi there,

I am somewhat perplexed by this thread. I feel quite alone because I have never got this thing to work on anything but the tiniest of test models. Three times now I've not been able to fully realize my final presentation for a project. I've basically given up on using this section tool.

I have no imported CAD.
I have no hidden geometry.

I'm using Sketchup 2017 Pro but had the same issues with 2016 Pro.
I get my elevation or section, delete everything not in view, purge, copy, paste into new project, delete walls etc.
I upgraded my video card to no avail.
I upgraded my system from 8 to 16 GB of RAM to no avail. I'd always had a feeling it was memory but it crashes well before it even attempts to do anything. I can see on my system monitor that i'm only using 19% of RAM this time.

The only thing I've got from this tool is one small room. I just don't understand how anyone has done anything useful with this thing. I'm at my wits end with it.

The resolution for me in this case ended up being removing the CAD I had imported. I separated my 3D elements to a separate file with no trace of the CAD and then the section tool worked as advertised.

I have also exploded imported CAD plans since then and it worked, too. I have used the section tool a few times since my first post without issue. I don't think my hardware made a difference. My work PC has a 2gb Quadro GPU, 24gb RAM and a Xeon 3.2 GHz CPU. At home I have an i5 2.8 GHz, 8gb RAM and 1gb GPU. Section tool works fine on both computers. (Edit: the PC in my original post is an office graphics station, these specs are my own PC's.)

The problem will be caused by something in your model. My office hasn't had a problem with this tool at all.

Try running Podium Tools and see what that tells you. I suspect that it is caused by rogue geometry. Have you inserted components from 3dw? Lots of components there originate from other modellers, which can be problematic.

Try purging your model and exploding any inserted images.

The tool simply uses standard Ruby script to cut the model. It operates on 'normal' SketchUp faces, there is nothing particularly special going on.

I haven't used anything from 3dw, only Podium Browser and a couple of my own textures which are exploded and have always rendered without issue.

I've just got it to work, but only after removing every single component and texture from the project.

So I guess that might indicate that my geometry is 'normal' and that something else is potentially the cause. And although there's nothing special going on, I know that my case is not the only anomaly.

Something isn't right here. Textures make no difference - they are ignored.

All the plugin does, is insert a plane at the line of the section, save the file, perform an 'intersect with model' operation for every group and component in the model, and delete the faces on the cut side of the section along with the cutting plane.

So the plugin is not doing anything complex or fancy.

What size is your model, and how many faces do you have?

Did you run Podium Tools?

It is quite possible that your CPU and RAM aren't up to the job if you are trying the operation with a very complex model.

The fact that the operation succeeded when you removed the components would tend to indicate that this is the case.

It's also worth reminding you that SketchUp has a finite size of face that it can create. If for example some of your components are say chairs with curved tubular legs, if you have modelled the tubes with lots of faces, with lots of chairs you are going to have a huge polygon count that your machine will have to deal with, and cutting across thin tubes bent around corners will create lots of tiny little triangles. We see this sometimes when importing files from other modellers, where the triangulation is very fine, SU meshes sometimes have holes.

This is why in the Browser, we have tried to model our content in such a way so as to reduce the polygon count as much as we can, but retaining reasonable quality.
This is also the reason why, periodically I will tell people that they need better quality items in a scene.

Many of our Browser items look great from a distance, but closeup you can see the compromises when the rest of the quality of the render is really high.
