I have a plugin user that is getting unusual Ruby console error messages, and experiencing SketchUp failure. The plugin has been in use for some time now, and this is is the first time this kind of failure has been mentioned. Each date marks the beginning of each line in the error message.

I have no idea what the following suggest. Help, anyone?

99% of the time there is no problem. If a plugin writer uses one type of machine exclusively, there are some situations that may cause a plugin not to work on another type of machine. Especially if the writer is not aware of those machine specific methods. Although it is rare, it can happen. If so, just post in the topic for help.

mysterd429, It may be a Ruby related problem. First of all, make sure that you do not have multiple copies of Dxf_In installed. SketchUp loads all of the plugins at once. If a plugin "method" has the same name as another plugin's, the system may fail. If the problem is not multiple copies, pm the error message, and I will ask for help.

Long live Analog. I still have analog media that "sings" to me. Their digital reproduction mask all the wonderful background nuances. Sorry for the off topic reminiscences. I play with a Koetsu on "The Arm".

mysterd429, Yes, I know of a Mac OS 10.5 user that uses Dxf_In v2.0. If you decide to install, and run it, open the Ruby Console just in case. If you get an error message, send it to me for analysis. Aloha, hdt

mysterd429, Thanks for the file. It contains one entity, a spline. Dxf_In doesn't support splines as the math is beyond me. Attached is a image of a SketchUp Pro's import of your file. If your drawing doesn't resemble this image, it is because SketchUp Pro's importer doesn't support the Objects in your Dxf file. Go here for a way to change Dxf splines into Dxf polylines.

It appears that the nature of the problem has nothing to do with v2.2. You should be able to run it on your system.

Get Dxf_In help from the Dxf_In Options menu to see which Acad entities are supported by Dxf_In.

mysterd429, Can you upload your Dxf file, here or pm it to me? If not, see if you can import the attached Dxf file of a box.Box00.dxf

mysterd429, You wrote "Dxf_in_v2.d.rb". Is that a typo? Is my understanding that Dxf_In v2.2 (the latest update found here) crashes your system, and v2.0 (the version found at http://modelisation.nancy.archi.fr/rld/....) results in a error message, correct? I do not have access to a Mac, and your help is required to identify the problem.

The only differences between v2.0, and v2.2 are some error messages. First that Dxf_In is for ASCII Dxf files only (Dxf_In can not read Binary Dxf files), and second that the Drive\Path\FileName.dxf must be standard ASCII characters (SketchUp Ruby will not read non-standard ASCII characters). I do not know how these error messages could cause SketchUp to crash, but if v2.0 runs without crashing, and v2.2 doesn't, I suspect the problem is with attempting to translate a binary file on the Mac.

For now, can you open SketchUp with Dxf_In v2.0 installed, then from SketchUp open the Ruby Console (Window > Ruby Console), then attempt to import the problem Dxf file. If you get a error message in the Ruby Console, please copy, and upload the error message here.

Thanks, hdt

This is a interesting situation. While it seems clear that the company owns the software, can they make a claim for the source code? My guess is yes, but they have to find the fellow (assuming he kept a copy). He probably scrambled the program because of the "sensitive data".

Depending on the extent of the modification required, if very minor, then perhaps a programmer at the level of assembly language might be able to make small changes with debug. I have done it with .com, and .exe files, but don't know about code at the current "state of the art".

Wow, look at the detail brought out by the render on the model's tape heads, guide fasteners, meters, etc.

Solo, did you down load the application, then run it? If you did, guess there wasn't a export / import feature. Looking at the "documentation", it seems that there is enough information to write an import / export program to produce a file that SU can read. However, I am not a expert on this matter, and it looks like a lot of work.

May be you need a new mouse? Borrow one to see if that's the problem. Most of use have more parts then we use.

About 1 - 2 years ago there was this fellow that posted great landscape images here. Try researching old posts to use his work as an example. Maybe someone else remembers who he was.

Addenda: Here he is.

When I built paper models, I used strathmore (sp?) sheets (not sure of the name) that had a thin hard layer on both surfaces, then notched, and fit the sheets together. More work, but nice edges on the model.

If locating the faces is sufficient, you can start with my code here. Just noticed that there is a link to Chris's post too.

Al, There is a snippet developed and posted here by Chris F. that scans the SketchUp window one pixel at a time, and identifies the face at that location. Not 100% accurate, but perhaps you can start with that?

Guess you better wash your veggies really good.

First good news for the ocean at the base of the nuclear plant.

Radiation levels fall in Fukushima seawater

Tokyo Electric Power Company says radiation levels have fallen in seawater near the Fukushima Daiichi nuclear plant.

The utility said on Tuesday it had detected 3.1 becquerels of cesium 134 per cubic meter of seawater near the water intake of the No.3 reactor.

The reading is 52 times the national limit, but the lowest since TEPCO began checking radiation levels near the intake after the nuclear accident that followed the March 11th earthquake and tsunami.

On May 11th, a level 32,000 times the national limit was detected at the same location due to a leak of highly contaminated water from the plant.

Cesium 134 was found in seawater 16 kilometers from the plant on Monday, but the level was below the limit set by the government.

The utility said the level of radioactive iodine near the water intake at the No.2 reactor was 160 times the limit on Monday.

But the reading was less than one-third of the previous day's figure.

TEPCO said it found radioactive strontium in seawater samples taken at 4 locations off Fukushima Prefecture on May 9th, but the levels were all below the national limit.

Radioactive strontium is produced during the nuclear fission of uranium. It was found in seawater off Fukushima in April.

TEPCO said the substance probably came from the damaged plant. The utility also said the detected levels were very low, but it will continue to monitor the seawater.

Yes, while nuclear energy seems to be a necessity, it doesn't hurt to rethink the alternatives. However I still have a question of the validity of many "green" options. Manufacture, and safe disposal of batteries, and "green light bulbs" may become a real problem in the future.

TEPCO tackles increasing contaminated water

The operator of the damaged Fukushima Daiichi plant says water accumulating in the basement of the No. 1 reactor building is contaminated with highly radioactive substances. The utility is battling to stop further leaks as the rainy season approaches.

Tokyo Electric Power Company detected 2 million becquerels of radioactive cesium per cubic centimeter of water in the basement of the No. 1 reactor building.

It speculates that radioactive substances from the melted fuel have leaked from the pressure vessel encasing the reactor core.

Large amounts of contaminated water in the plant's buildings are hampering efforts to contain the situation.

TEPCO has created a map showing the distribution of contaminated water at the plant to prevent a recurrence of the accident in March, where 3 workers were exposed to radiation by stepping in contaminated water in the basement of the No. 3 reactor's turbine building.

Rain showers that began Sunday are causing the water levels in the No. 2 and 3 turbine buildings to rise at a faster pace of 3 to 4 millimeters per hour.

The company plans to set up a cooling system to circulate decontaminated water back into reactors. The system is expected to be set up in July.

Until then, the utility needs to come up with measures to prevent further leakage, such as transferring the water to a new storage site.

Rain increases radioactive water at nuke plant

Heavy rain has increased the volume of highly radioactive water building up inside the disaster-hit Fukushima Daiichi nuclear plant.

Contaminated water already floods the basements of the turbine and reactor buildings, partly due to water injections to cool down the reactor cores.

Tokyo Electric Power Company, or TEPCO, now says water levels rose faster on Monday as rain poured inside the badly damaged buildings.

In the basement of the No.1 reactor building, radioactive water rose by 37.6 centimeters during the 24 hours through Tuesday morning.

At the No.2 reactor, the level of water rose by 8.6 centimeters in an underground tunnel extending from the building.

The water in the tunnel's shaft is now only about 39 centimeters below ground level. The utility is speeding up work to seal the opening.

TEPCO is planning to decontaminate and recycle the radioactive water as coolant for the reactors. But the system won't be in place until July at the earliest.

In the meantime, the utility is studying steps to prevent rainwater from seeping in. It will also consider new storage sites to which the contaminated water can be quickly transferred as the rainy season approaches.

High radioactivity levels at No.1 reactor

The operator of the damaged Fukushima Daiichi nuclear power plant has reported high levels of radioactive substances in water that has accumulated in the basement of its Number 1 reactor.

Tokyo Electric Power Company says a water sample taken from the reactor building's basement on Friday contained 2.5 million becquerels of radioactive cesium-134 per cubic centimeter. It also detected 2.9 million becquerels of cesium-137 and 30,000 becquerels of iodine-131.

The levels are almost the same as those already measured in contaminated water in the basement of the Number 2 reactor's turbine building.

Water contaminated with highly radioactive substances has flooded the reactor building's basement, apparently after leaking from holes created in the reactor's pressure and containment vessels in the fuel meltdown.

Under the utility's plan to bring the plant under control, a circulatory cooling system is to be installed to decontaminate radioactive water and use it as a coolant.

TEPCO says it will examine ways to decontaminate the water, as its radiation levels are too high for workers to approach.
