trueSpace can't boolean my object !

[Emmanuel]

I've designed a hollow-door to be cutoff from an aluminium board.
The cutoff design was created in Affinity Designer, my favorite vector-drawing software

My client is happy with the design and now he wants a 3d preview of it, blended in a photography of his interiors.

I can export my 2D drawing to AI or EPS format, and import it in trueSpace, but I am stucked with trueSpace boolean tools that refuses to cut off. Both Modeler and Workspace boolean tools are failing.
I have no other 3D software (only Sketchup) to experiment and I can't figure how to generate a 3d model from that design...

Do you have some tips or tricks ?

You can try AI and SCN files, attached in the zip file below.

Have you tried quadrifying the geometry before boolean? Sometimes a bit of extra geometry helps when doing a boolean operation in trueSpace.

[Emmanuel]

Yes, I tried to add details, triangulate, etc.
Resizing the objects also helps : boolean works better with large objects.
But there is still too much errors on Modeler side ; and Workspace simply freezes...

I guess I should use an other software for that particular case.

I brought your subtraction object into Rosetta, used Heal vertices, Clinton's Fix Bad Geometry's - Delete Floating points, Quads, and Quadrify
Using Select Quads was the only way I could select all Geometry
Finally, Boolean Subtract your subtraction object from a Cube that had 1000 x 1000 x1000 segments
tS761 Door.RsObj

.
Exported the tS761 Door's Editable Shape
Created a Cube in tS76, swapped the object Editable Shape, exported as a cob from Model
tS76 Door.cob

I think I got it! I tried and gave up and then saw trueBlue's boolean with cube trick.

Number of steps:

Open AI file in Illustrator and add fill and stroke.
Save as SVG file
Import SVG into trueSpace workspace with options:
- Zoffset = 0
- Uncheck Constant Color
- Always Close Curves - cause 1 curve wasn't closed
- Show Polygon Edges

PE mode, Dynamic Sweep on the big piece, with Boolean on release to close the open bottom - slow process
Boolean combined all the smaller pieces into 1 then dynamic sweep it - both also slow
Create a short cube 100x100x1 divisions, shorter than the big piece and shorter than it
Boolean subtract the combined little pieces from the cube
Boolean intersect with the big piece.

Cube is the final object and the scene file shows how it looks before boolean steps.

While working on this I noticed some shortcomings with the SVG import that makes it more difficult to model with the imported meshes, so some changes are needed.
Edit: note to self - bridge was causing issues, turned it off

[trueBlue]

Much better!
Same object with a cleanup
Lowered two elements that were sticking out, deleted floating points, and removed orphaned material
Dang!!! 16.6 MBs

Waow, you guys are definately trueSpace geniuses !


Your SVG import tool Clinton is saving my life !
So part the trick was to fill the AI curves and import it via SVG I would never thought about it that way !

Once again, this workflow opens many possibilities. It builds new bridges between 2D and 3D.

Many many thanks again to all of you !

I am still using Photoshop CS3 (never upgraded since 2012, yes, just like trueSpace )
But my son, who is using a recent version, told me the best solution was to use the 3D features of modern Photoshop :
Simply load the drawing, convert the layer into a 3D layer, then export as OBJ. Easy !

[clintonman]

My last version of Adobe is CS5 and the export 3D from Photoshop works pretty well for your complex shape. I still had to stroke and fill to get it to work. One more tool for the belt, thanks for the tip.

The youtube link doesn't work for me.

dont want to spoil the fun, but why didnt you do it in the 2D vector software to be cut out like that? :) and you could only extrude it in tS and thats it.
