Hi Carlos, right now I just don't have things set up to export multiple views like that, I think I'm going to focus for the first release of this just on getting one single view at a time and try to make sure that's working ok to begin with.

Then in the future maybe I could add in a option for "All" under the "Projection view" option that would then put in 4 views into the same file... Is it important to you for the views to remain in separate files rather than arranged in a grid on one single page?

Hi Michael,

4 Views in the same file is even better, actually with 4 separate Files/Views i'll end up gathering the 4 in 1 file/drawing.

Thanks.

Carlos

Hi Carlos, one other question - with 4 views in the same file do you expect the page to be oriented as "landscape" type mode or still "portrait" type display mode?

Hi Michael,

That's how I understood it, the numbers displayed would be that custom resolution.
It's not worth the trouble if it's too complicated, I'm sure I will quickly get used to estimate resolutions in that fashion.

Landscape, please ; )

Hi Marc,

> That's how I understood it, the numbers displayed would be that custom resolution.

Yeah unfortunately it's not currently easy for the dialog code to know that resolution at the point that the dialog will be displayed, it's something that's calculated by the hidden line removal engine after it receives those parameters to use...

It could be possible to recode that, but it can be somewhat inconvenient in general for UI code to interact back and forth with low level engine code.


That same resolution will control not only the shaded image resolution, but also the resolution of the depth map that's used for hidden/visible determination. So if you are getting some smaller size details not coming through that will be a parameter you can increase to make the depth map more fine grained too.

hi michael

What you suggested with setting the units to say .2 is perfect - didn't think it would work like that! Thats why you're the programmer and I'm the illustrator ;-)
Great work, can't wait to give it a test drive - I have lots of big STEP files waiting.

Will the dxf export support layers in the next beta?

Hi Max,

> Will the dxf export support layers in the next beta?

It's on my list of things I'd like to get done with this hidden line removal work but I have not got to the DXF part of the work quite yet.

- Michael

Hi Max, also I'm not really sure if the DXF export should have all these exact same options as the AI/PDF export like for generating outlines and silhouettes in addition to just hidden/visible lines.

For one thing I'm not sure if I'll be able to put in an embedded bitmap in the DXF file like I can for AI and PDF files.

So the DXF export may be a bit more simplified, with just options for whether to generate hidden lines or not.

- Michael

---

Please, I really need the DXF format to export layers (styles).
Because: if I export MoI > AI it has layers, then ok, I convert from AI > DXF\DWG, and import into AutoCAD. The imported drawing is not precise. It has slightly overlapping lines and makes it impossible to hatch.
If I export MoI > DXF and import in AutoCAD, the lines are perfect. But no layers. :(

Hi, wouldn't it be easy to select by linetype in Autocad with quick select?
You could then assign your selection to another layer.

Marc

---

If you are on a mac a free alternative (for the moment) is exporting from rhino. Thats what I do, but the direct MoI to AutoCAD workflow is ideal.

---

Also because I need a dxf output with the upcoming hidden line feature.. And layers

---

Ok, this is getting pretty close to being finished up... I think that probably tomorrow I'll have the hidden line removal stuff wrapped up and then I have a short list of some other things to look at and then I'll be ready for a new beta. So not too much longer.

I have just been reading through this thread Michael, excellent work you have undertaken, which I have no doubt will save masses of time when exporting to vector formats. I was also looking for information on removing the seams, which would also be handy in the general moi viewing window, is a script to do this better before saving to clipboard, so it could be used in the moi view window as well.
