I could use that script nr 1, but cannot find it on Didiers website. Does someboy have a link

What I meant that for placing multiple sections or sections that only affect parts of the model, no Ruby is needed. See attachment for a simple example...

multisections.skp

TIG:s SectionCutFace ruby script that I mentioned makes a face to fill the gap left by a section plane in a hollow wall, for example.

Is this your design? What's hysterical about it?

Is the wooden part the addition?

I see no great problem about this kind of approach to restoration, even if the age and simplicity of the original might also allow a more free way of treating the addition, if the situation is itself not too sensitive. Of course, if the surroundings are very uniform and well preserved from the same period, a more "modernist" attitude would perhaps stick out too much. But this is an ever ongoing debate...

Clean and informative presentation-maybe it should include an image of the "before" state.

I also liked the SU image. It reminded me of the (late, I think) British architectural illustrator Gordon Cullen. His book Townscape has many such simple and powerful illustrations.

Well then I don't understand why a LO document with 11 pages (one image per page - A3 document) based on a SU model of 13.4MB would turn out to be 185MB. That is pretty rediculous.

There is only the one model listed in the window where you specify the model to link.

Juju,

I think this quote from Barry pretty well explains what is happening:

@bjanzen said:

It does take a snapshot (png) of your model for 2D space, so if you have large paper size, your document will grow in size,

PNG is a lossless image format quite similar to TIFF, so it will easily take quite a lot more disk space than the actual SU model. And if the "snapshot" is taken of an A3 sized model "window" at 300 pixels/inch it would be quite huge (about 17 million pixels) Uncompressed that is about 50 megabytes of RGB colour. PNG uses a lossless compression method, so the result of about 15MB per image is rather to be expected. I tried saving a photograph (enlarging it) at the same resolution from Photoshop, and got an about 12 MB file.

I guess the alternative would be to regenerate the model windows every time you turn a page or otherwise change the view, and that might be even slower than the present method.

I agree that something ought to be done about this. I always fall into comparison with the old workhorse PageMaker and its speed.

Dear Alan,

A ruby that generates a circle with a given side length might be useful.

Select the circle's centre, and then activate circle_side_fixed script

Enter:

Number of sides = n (24 by default)
Side length = L (e.g. equal to the tree line component length)

The Ruby then calculates the correct radius (L/2sin(360/n) = 130,345.09430 mm for your tree line) and draws circle. The script could be generalised to include polygons of fixed side length. Saves the hassle of calculating the radius.

Regards,
Bob

Bob,

You don't need a Ruby for this:

Draw a circle with the wanted number of segments but any radius and group it (if it is not the only object in your model)
Edit the group. Select the Tape Measure tool and measure one segment of the circle.
Type the segment length you want(the value appears in the VCB), and press Enter. SU asks if you want to resize the group/component. Click OK. Done.

Note that in SU, the circumference of a "circle" is smaller than that of a real circle with the same radius, as the circle in SU is a polygon.

Theme "a short tutorial".

The bad thing about PLN files is that they are pretty much useless if you don't have the accompanying library files, even if you have access to ArchiCad. Archicad comes in many language versions, and they have significant differences in the standard libraries. If the object file is missing, only thing seen in ArchiCad is a placeholder symbol. It is like an AutoCad file that consists entirely of XREFs.(I really do not understand what the enormous file sizes of Archicad consist of).

I too have access to ArchiCad, and will be glad to help, even if I am an eternal newbie with it.

Anssi

I don't know much about Mac user accounts, but even if you give your wife an Administrator account, she won't be able to see your personal files. And I don't think SU wants even that to work, just a normal user account ought to be enough.

Anssi

Also check that your model is not very far (miles, kilometers) from the SU origin point, or that it does not contain some extraneous geometry somewhere far away. Both these cases confuse the OpenGL system, which really does not work well with either too big or too small dimensions. This happens easily with imported CAD files, especially ones with geographical survey data.

Anssi

Thanks Coen and the team! The change was a real improvement!

Anssi

There is no workaround that I know of, but a component that is "hole-cutting" or otherwise glued to the surface, will follow if you use the push-pull tool on the surface.

Anssi

I think that the empty PNG has to be bigger than 10 x 10 pixels for it to work. I once noticed that a 2 x 2 PNG made by myself didn't work, but a bigger one from the forum (by Alan Fraser, if I remember right) worked perfectly. I cannot say where the limit is. The 99% trick is a good workaround

Anssi

I cannot post the link, but this bug has been noticed before. It seems that the PC version cannot read Mac-formatted image files. Also, I think(not sure) that with Mac SU you can use images with the CMYK colour space, whereas on the PC you cannot.

Anssi

At least number 1 is already possible by using groups or components, and most of the others can be fairly well achieved by nesting groups.

TIG has made a quite well functioning Section Cut Face RUBY script, that can be downloaded from Didier Bur's Ruby Library Depot, or the Scripts forum under the Ruby Discussions subforum.

Anssi

I recognize the syndrome. It also plagues me with CAD applications.

On the other hand, if I leave the sloppy bits, it usually is certain that I will shortly have to make some modifications to my original design, that the small errors make a hell to carry out.

Thanks. We have both been using mm as a unit. When exporting ive used mm (decimal). One of the options is scale but those fiels is "grey", I can not use scale option. I dontt hnow if that is a part of the problem.

I guess that you want a 2D dwg file? In that case, you must select one of the standard views (top, front.... etc) and select Parallel Projection from the Camera menu before exporting. The greyed out fields in the Export options dialog will now be active.

Anssi

Good idea and a nice model. You should change the tubular railings of the slide, they look dangerous, especially in the curving part hands or feet might get stuck.

If a hardworking few can produce this superb forum, why can't Google with all its resources fix their forums? (sorry, silly question).

What most amazes me in the Groups is Google's "Not invented here" attitude toward forum software. After quite a long time they with their army of programmers still haven't made it even decently functional. Compared to this it is like Paintbrush versus Photoshop.

Anssi

Anything wider than about 3000 pixels will not save if you have Antialiasing on in the Export options.
