Full Version: Is there a script that will replace a shape with another shape?

Show messages: All  1-3  4-18

Hi Matadem, it would help me understand if you could make a .3dm file with an example of the starting shape, the inputs to the script and the desired result.

the one on top is what I have...the one at the bottom is the desired outcome.

Tnx!

Hi Matadem, if your objects are regularly spaced like that you can use Transform > Array to do it.

Step 1 - use Transform > Copy to copy circle onto lower left element.

Step 2 - Use Transform > Array to make new pattern over top of old one.

Step 3 - Cleanup to Remove old objects - select newly created objects, invert and delete.

Looks like this:

Or to simplify cleanup you can draw in a rectangle for the cell size like this, then you can delete all the old shapes, move the new shape onto the lower left corner of that cell and use the lower left to upper right corners for the array spacing. Then you'll only have that one spacer rectangle to remove for cleanup.

Good day.
no the array was just as an example ..they are all over the place.
Tnx!

Hi Matadem, can you please post an example that more closely matches your actual case?

- Michael

You could use BoundingBoxCenterIndividual from here to place a point at each selected object's center:

Then CopyToPoints:

Yep that was that! ;) Made in the past!

Thanks works great.
Michael please search option for commands and shortcut....without the need to go to option to look it over.

Thanks!

I was wondering - if the object is named - and i might be interested to
swap all 'object 1's - Circle" with 'object 2 - Square'
would that be an easy script?

i'd want this streamlined where it is not creating a named object to make it work....anyway got the result working fine...

Save below text _____ as: ReplaceByTarget.js.
or use the zip...
SELECT YOUR TARGET SHAPE eg. the square
run: ReplaceByTarget.js
then
SELECT OBJECTS TO REPLACE (eg circles),
RIGHT CLICK DONE.

IF YOU WANT TO REPEAT DELETE OR RENAME THE OBJECT NAME OR RUN THE "CLEAR" SCRIPT IN THE ZIP
THIS IS NOT EXACTLY AS I WANTED IT BUT WORKING FINE FOR PROOF OF CONCEPT....

the read me is "ai" and it seemingly blames itself or "MOI" for not getting this 100% as required...

------------------------------------------------------------------------------------------------------------

// ReplaceByTarget.js
// MoI3D combined one-command version.
//
// This avoids MoI's "pick target during command" selection issue that I could not seem to get working.
//
// Workflow:
// 1. Select the replacement/target object.
// 2. Run ReplaceByTarget.
// -> The command saves that object as the target.
// 3. Select the objects you want to replace.
// 4. Run ReplaceByTarget again.
// -> The command replaces the selected objects with copies of the saved target,
// centered by bounding-box center.
//
// To change the saved target:
// - Select the current saved target object and run ClearReplacementTarget,
// or run ReplaceByTarget_ResetTarget if included.
// - Then select a new target and run ReplaceByTarget again.

Here's a simplified version.

This one does not do anything with selection, you put in 2 names and all objects with name #1 are replaced by objects with name #2

tested this and like its simplicity - thanks Michael...
Please can you let me know, where i change the dialogue box text
to suit my way of thinking...simply put, I'd like it to read:

REPLACE Object(s) Named:
[Circles]

WITH Object Named:
[ Square ]

---

Hi stefano, the text for these is in ReplaceNamedObject.htm

> REPLACE Object(s) Named:

That's on line number 15, look for this:

Name to be replaced:


> WITH Object Named:

This one on line number 27, look for:

Name to replace with:
