It looks like after moving entire model, Zero coordinate (in profile view) starts from intersection of centerline of the hull with DWL. So it is need to move model in opposite (X) direction the same amount as shown on first vertical grid-line.
Nope, that was too early to celebrate. I have another model which has X=0,Y=0 at end point, but grid was offset too. I had to move entire model to negative X, to get grid start from 0
Any ideas why it happens?
It looks like I found the answer on my own question 😉
The coordinates of end point should be X=0,Y=0. The grid starts from Zero again.
I forgot to put original DS file in zip archive. DS half box 10x5x3 feet – goes separately (used for DXF export).

Here are files of 10x5x3 feet half box exported from DS as DXF, converted to VRML, exported back to DS. Final half box size is 10x5x3 METERS. Model need rescaling to proper foot length and minor corrections (make some points “corner” points). Other than that no big problems.
More problems created going trough more conversions. [file name=Box_10x5x3_DS_2_DFX_2_VRML_2_DS.zip size=26655]http://www.delftship.net/delftship/media/kunena/attachments/legacy/files/Box_10x5x3_DS_2_DFX_2_VRML_2_DS.zip[/file]Attachments:
All the faces were defined twice. I remove those double faces. In addition some faces used points which were at the same location in 3D space but also defined twice.
How can I recognize double (defined, etc.) faces and double points in DS?
I might created some double faces, just because DS did not give me any indication it were there
after I create it. Double points might were created during import. So, how can I see in DS if
points, faces or edges are doubled? Can I see it in DS screen or do I need to look in DS *.fbm
Thanks for the file, now when I have correct DS model, I can export DS file and
compare it with file for import and, hopefuly, find out what the difference is. I will report back
about my progress/problems.
I was able to make sides by creating faces and extruding edges, but I still cannot make bottom. File attached. I need some step-by-step tutorial ;)) [file name=SU_Box_10x5x3_inch_from_dae_2_VRML_feet_DS_1.fbm size=25008]http://www.delftship.net/delftship/media/kunena/attachments/legacy/files/SU_Box_10x5x3_inch_from_dae_2_VRML_feet_DS_1.fbm[/file]Attachments:
It looks like I figure out (or may be completely lost) what is going on with SU. I am using SU 7.1 (could be different for other versions).
I need to find volume of symmetrical irregular shape vessel created in SU. So, the better way to do it is to go by displacement and use Delfship (DS) for this. So, I need to export model from SU and import it in DS.
What I tried as experiment: Make model in DS, export it in DXF format, import it in SU, export it in COLLADA, covert to VRML, import it back to DS. I have got different results – needs more research.
– DS can export model to DXF file as Metric(meters) and as Imperial(feet) units (no indication of units in the file).
– SU imports DXF file in Imperial(feet) units.
– SU exports model to COLLADA file in INCHES ??? (that why I got over sized model). YOU NEED TO RESCALE MODEL FROM FEET TO INCHES before exporting to COLLADA. For some reasons, SU 7.1 have problems to import created itself COLLADA file back to SU.
– Need to convert COLLADA file to VRML 1.0
– Export it to DS. DS will give you model in METERS.
I made model in SU 10x5x3 FEET. Rescaled it to 10x5x3 inches. Exported it as COLLADA file. Converted to VRML 1.0 file. Imported it to DS. Now I have DS model as 10x5x3 METERS.
Could somebody help me how to make this imported model compatible with DS? It just give me strange shape in 3D. File attached.

Have you checked your project settings? It seems some are having issues if they import DXF (IIRC; see the Sketchup threads) when the project and the source app are one in metric and the other in imperial.
Yeah. It is me who experimenting with all this export/import things between different 3D/2D software ;))
It could be just SU 7.1 problem exporting into COLLADA file. Even if SU shows smaller (exported) model(Metric/Imperial), it still exports over-sized result.
I converted DXF (exported from DS) to VRML and imported it back to DS – no problem. It disables some functions in DS, but workable.
I would like to have DS Pro one day, but for now, DS Free is good enough for me to work with symmetrical models. I just need to make them from paper, that why I play with all this export/import staff.
You can move them all by using the menu’s “select; all” feature. Then, use the menu’s “transform; move” (to translate) all the selected lines.
Thanks! Transform -> Move works. I just need to figure out how to reduce numbers of points in imported file – too many of them to work with. Another problem – size. It is off big time. Length is 81m instead of ~7m, etc after importing, but it is NOT DS problem. More likely converter problem.
Well, it looks like DS is limited to symmetrical hulls. It is OK, just need to remember about it.
So, if I import half of the hull DS will work correctly. But how can I import asymmetrical hull or the hull with asymmetrical super-structure in DS? I cannot just cut half of it….
That will be very hard to do because imported model has 22784 faces, 34304 edges, 11521 points, 0 curves
My computer just freezes trying to render the screen. Anyway, I need to move ALL these points. And put hull EXACTLY at center line. I do not see how I can accomplish this. “Move to baseline” tool does not work – it already aligned hull the best way it could.Attachments:
Attention to DS users who making models in Metric units and want to export it to SketchUp.
It seems like SketchUp (SU) needs Imperial units to correctly import DXF file from DS. DS generate different values in output/export files for projects using different units. But… Exported file does not have any indication what units were used. SU imports DXF file assuming it was created in Imperial units.
If you want SU correctly import your model made in Metric units, change your existing model project’s setting to Imperial units
Project -> Geneal tab -> Units -> change it to Imperial.
Export your model as DXF 3D (mesh or poly lines).
Choose Metric template in SU. Import DXF file from DS file to SU. Now you have correct size of the model and Metric units.
If you do not do this, you will end up with problem like on the picture. These 2 IDENTICAL hulls have the same size in DS – 10m/32.8ft
The one which looks small (incorrect size in SU) was exported from DS when model had Metric units. Bigger one (correct size in SU) when model was using Imperial units settings.Attachments:
