How are you trying to install these extensions ?
More details would help us to help you...

Note that some extensions need a helper Lib installing - LibFredo is one of these...

With the PluginStore you download the RBZ file for the extension, and save it to your Downloads folder.
Do not try to open it with SketchUp.
It needs installing...
Within SketchUp v2021's Extensions menu open the Extension Manager [it's in a different menu in earlier versions]...
Click the 'Install Extension' button in its dialog.
Find the RBZ and SketchUp automatically installs the contents of the RBZ for you...

When an extension needs a helper Lib also install that and restart SketchUp to ensure everything gets synced...

Some authors like Fredo & thomthom use supporting Lib files, which are available to download and install [LibFredo], then after SketchUp is restarted the tools should load and be available.
However, don't fall into the trap of thinking that every extension is listed under the Extensions menu...
Read up on each particular extension's usage - e.g. Fredo's Tools is accessed through the Tools menu list or its Toolbar entry...
Some other tools are also activated from the context-menu... read up on each one...

Doesn't Archicad have 'combine by material' option when exporting to external file formats like fbx\obj? If you by mistake have 3ds Max- there are some soog solutions..

NEW UPDATE 🎉
Update checker, settings, toolbar, sound effects, bug fixes.

Docs comming in v11.0!

Please consider preserving last used settings -it would be a HUGE improvement; its so annoying to restore the same settings over and over again

I think you need to ask the Paypal why taking them so long to complete the review of my purchase.

We have spoken with PayPal and got the same info you did. The decision making around accepting payments is with PayPal. We can't influence their actions.

Personally if I used their system to purchase and they kept my payment in a pending state for this duration I would cancel the payment and try again. I would not let them keep my funds in limbo.

This is why I advised via email, and here, you should cancel the payment.

Is is possible to combine multiple fredo-splines. I want to join them at their endpoints, then have the two original splines behave as a single spline that can be edited/adjusted going forward.

Combining 2 splines into one would cause each spline to be (slightly) modified to ensure continuity at the junction.

This is not supported currently by FredoSpline, but can probably be done (although not trivial in the general case).

Same, by the way, for the split of splines, that is, cut a spline into pieces which are also splines.

Currently, the only thing you can do is to extend a spline by its extremity.

Because the different "strands" of the drapery needed to be different lengths and pinned at different angles, I decided to scrap trying to use the original circular array of rectangles and am modeling each strand one by one... I don't even have the original component anymore! ​

I think my original issue was the way I was selecting the geometry. I was able to model one of the strands, attaching file.

drapes.skp

The other issue I've come across is once I model the cloth, I realize I needed to add more pins, but because I want the pins to be in a circular shape, if I toggle the drape off, I can't tell where to put the pins so they catch the cloth.

Is it possible to add pins after modeling the cloth?

If anyone has a better work process on how to model the referenced drape, please let me know.

Hi Hal! Any news about this small issue?

Fixed!

Update your FlexTools / ComponentFinder to the latest version 😉

I'm sorry, but I don't resonate with your English.
As I said, the subdivision toggle button is there. It is stable AND it is instant. I don't know what else you mean. You need to be more precise.

Thanks a lot for you quick answer!
I'll try and let you guys know! Thanks!

*** EDIT ***
That fixed the issue! Thanks again!

Did you listen with sound?

No, so I went back and listened and yes, he is in sync. Well done. 😄
