Graphicaly creating objects using Marquee to shape it

[Anonymous]

Hello,
We just upgraded to V19 from V15 . With V15 I could take any existing 3D
element ( a slab or even a existing library part) and use the marquee tool to isolate or slice a portion of it and save this 3D view as a library part.
I cant seem to do this in 19 any more. The part created is always the entire
element without the intended cut away needed.
Can anyone please help?
Thank you
Chuck

If you select the element in 3D and use the File\Libraries and Objects\Save Selection As\Object command, then yes, it will save the whole object.

But if you use the File\Save As command to save it as a GSM format, then load that file into your Embedded Library, it will create the geometry cut by the Marquee.
At least that's how it works for me in AC 19.

Thank you for your reply.
I did try to do what you suggested but after loading it in the embedded library the object preview window says :

"Invalid 3D symbol. Open the library part for editing and check its 3D script for errors."
Not sure what to do next.

Thanks,

Select the placed Object and use the File\Libraries and Objects\Open Object menu to open it.
Then activate the 3D Script and then click the Check Script button. What is the exact error it tells you?

Hi laszlonagy,

2 error reports come up

(1) Key words cant be used as variables at line 8168 in the
3D script of the file zzz script of the file zzz.gsm

(2) Parameter expression error or unnecessary end comma
at line 8168 in the 3D script of the file zzz.gsm

I do use this method a lot for very detailed cut outs on 3d construction docs
so if you can figure this out for me I will be very happy again..

Thanks,
Chuck

The two error messages are probably related because they both appear in the same line of the script.
Try to resave the geometry and when saving, give it a proper name, not "zzz".
Hopefully, that will fix it.

Ok..
I tried to cut a shape out of a slab with marquee again and saved as a "proper" name (cut-out-1) .....no error messages this time ....
BUT
the resulting gsm part included not only the entire slab but
everything else in my model even though I selected only the 3d cut out in the 3d window when saving it.

???

With the Save As command everything visible in the 3D Viewpoint is saved. So define the Marquee in the Floor Plan and display only that in the 3D Viewpoint.
Alternately, select only the cut Slab in 3D and press F5 to display only that single element in 3D. Then use the Save As command.

(The Save Selection As command is different - as its name implies, it saves only the things you select.)

Hello again..
It saved the object again as the entire slab and not the cut out defined by the marquee again..
HOWEVER..In the object 2D preview it shows it correctly cut out.
The plan view in the model also shows the cut out but in 3D it's still the entire slab.
Is it possible that there is a glitch that needs to be addressed?
I do have the latest downloaded V19
Thanks,
Chuck

Sorry, I don't know what could be the problem.

Try to reread this thread and do it again. It should work without error messages or incorrect 2D/3D.
