Absolutely amazing plugin ! Thanks for make it free

Looking for some example/tutorial cause i am completly lost. I want to create basic paramtric building (volume + balcony),but can't find the way to do it

Thanks !

I have to make those snake skin like things, any idea how to do it?

Sorry for the late reply. It's maybe possible to model this "Snake Skin". Here's an hypothetical plan:

Download Tiling.schema. Make sure downloaded file ends with ".schema", not ".txt".
Open Nodes Editor.
Right click in void to display context menu… Click on "Import schema from a file". Select "Tiling.schema".
Design elementary shape with SketchUp native tools or other plugins. Let's call this shape a "Tile".
Make a "Tile" component. Right click on this component in main SketchUp window. Select "Parametric Modeling > Extract Shape From Group Or Component". "Tile" appears as "Draw shape" in Nodes Editor.
Replace "Draw box" node with "Draw shape" node. Connect "Draw shape" with other nodes.
Use "Copy" node(s) with "X/Y/Z Position" formula(s) to spread "Tile/Draw shape" in 3D space.

There are videos available on YouTube but it's more a plugin overview... I recommend you to import examples: Open the Nodes Editor. Right click in void to display context menu… Click on "Import schema from a file". Select a ".schema" file. Study how nodes are filled and connected. There is also a Wiki.

Some of the supplied schemas require particular models for them to be expanded correctly. Can you please provide those models?

I have been using Parametric Modeling for a while. I find it very useful in solving some problems. I hope you are continuing the effort.

When you export a parametric schema, everything visible in the Nodes Editor is stored in the .schema file, even custom shapes (extracted from SketchUp viewport).

A parametric schema can be exported from a model then imported in another model, without geometry loss. The only things not embedded in .schema files are materials textures.

Traupmann

Perhaps I am doing something wrong. I started with a blank (new) Sketchup model, then use Parametric Modeling to Import a Schema. I get the Schema, but not any structures of any sort in the model space.

Here are screenshots of the Decking On Pedestals.schema.

I don't see your screenshots. Did you forget to attach them?

Maybe an error is occurring in background. Can you try to:

Open the Nodes Editor.
Open the SketchUp console.
Import a .schema file in the Nodes Editor.
Execute this code in the SketchUp console:

ParametricModeling;;ParametricEntities.redraw

Report the error here?

CODE: SELECT ALL
ParametricModeling::ParametricEntities.redraw

Excuse my ignorance, but by Sketchup Console do you mean Ruby Console?
if so, an error report is in the text file below.

I have included the SketchUp file as I attempted to execute it.

Ruby Console Error Message.txt

SketchUp File.skp

Yes, I meant the Ruby Console Thanks for the error log. I suspect a conflict between Layers Organizer and Parametric Modeling plugins. Can you try to:

Disable temporarily Layers Organizer plugin.
Restart SketchUp.
Import again a schema in the Nodes Editor?

Traupmann

The disabling of the Layer Organizer worked for all of the provided schemas but two. The files are below.

Decking on Pedastals Results.skp
Curved Shelf Result.skp

Here is a schema I developed
Arch.skp

Can you advise how to pass schema files?

Hello. This is an amazing tool for me. It has immense potential. I am a lecturer and I teach this plugin to my students, especially. Know it is currently under development, so I think you will consider my suggestions.

All my problems are with nodes First, it would be great if they could be locked, grouped, and ungrouped with a right-click option.

The undo and redo shortcuts do not work as I expected. For example, when I accidentally add a box to a crowded node screen, the "ctrl+c" combination does something else instead of removing it.

Especially in complex jobs, nodes get mixed up. To prevent this situation, you can add icons that can be personalized (such as color, geometric shape) on the upper right corners of the nodes.

Finally, if windows run in tabs, you will have done an excellent job of efficiency. My English isn't very good, but I wanted to congratulate you and give you an idea of what I think can be improved. Wish I knew a little bit of coding and could help you. Respects

Hello. This kind of feedback makes me very happy! It's one of the reasons I code and share plugins.

@unknownuser said:

A lot of things are not documented. Parametric Modeling plugin Wiki really deserves some love

@unknownuser said:

To be honest, the developement of this plugin is in stand-by. I'm busy by other projects. That's said, suggestions are always welcome

@unknownuser said:

This sounds not "easy", but a must-have option! I agree.
About organization, one can add "Post-it" nodes. Right-click in void then choose "Add a comment node".

Try to press "Escape" to cancel... If it's too late: right-click on the node then choose "Remove this node".

@unknownuser said:

Yes, I could add more visual landmarks. I note your idea.

SketchUp HTML Dialog API (used by this plugin) don't support tabs, but I could add tabs inside the plugin's window...

Thanks. Where do you come from? I'm curious

Parametric Modeling plugin code source is online.

Hello again.
I am from Turkey and I teach in the field of woodworking industry. I use many different plugins, but "Parametric Modeling" is very convenient especially for cabinet type furniture after creating a library. So, I always tell my students about the power of open source and how they can contribute to it.

As I mentioned in the previous comment, excellent results can be achieved if something is added to reduce the clutter in projects with many nodes. I hope you continue to improve. Thank you again for what you do.

how would you generate the ability to move an item randomly but within a fixed range of value?

For example, I would input the formula below in the "X Position" field of the "Move" node to translate on X axis an entity between 1 and 5 meters (if the active model uses meters).

rand(1.0, 5.0)

The "rand" function returns a random number in a range. First argument is the minimum number, second argument is the maximum.

Alternatively, one can use variables instead of hardcoded values if variables are defined in or connected to "Variable ..." fields of the "Move" node. Then the above formula becomes :

rand(a, b)

Sorry for the very late reply.
"Decking on Pedastals" appears empty.
"Curved Shelf" appears incomplete.
For both, I don't know why...

Bravo and thank you for this great schema! I'll include it in the next Parametric Modeling plugin version.

Inside Nodes Editor, right-click in void. Select "Export schema to a file". Share exported .shema file

Thank you Samuel for this awesome extension. I spotted this a few years ago and tried a few things out of interest but didn't get far. I returned last week after getting frustrated with the native dynamic component editor. Thanks for your great modifications since it is a very useful tool now. Well done.

Thanks also to Traupmann for the Arch schema. I changed the numbers a bit but got a Bug Splat after a few minutes.

I'm building a schema with some similar components and found two strange things

The components often disappear in SketchUp upon modifying the schema. Adding and deleting nodes sometimes makes them reappear.
Some nodes do not appear to be calculating but seem to have correct formula in them (see attachment)

Greg, I'm happy to hear this plugin is useful!

Does this happen when you are typing a formula?

@sketchucationgreg said:

The preview in Math nodes such as Divide can be empty. This is a known issue. It's only a display bug.

Can you please send me your .skp or .schema file?

Hi Samuel. Thank you for looking at my post.

Yes.

Thanks so much for letting me know that Samuel. I wasn't sure what to do next with that one.

Schema attached.
