Be advised that execute_script is very buggy on Mac. It will mangle the string sent if it contains ";" or "," and probably other chars as well. Also "document." doesnt work.

Edison, I think I may a have a workaround for you. I am certainly not an expert at dealing with contours, but through recent experimentation and the availabilty of newer scripts this could be what you need. You'll will need to check the accuracy of the "re-segmented" contours, however, to see if they are within the tolerances/lever of accuracy you want. See the attached .skp for a mini-tutorial. You will need the Weld.rbby Rick Wilson and the BezierSpline script setby Fred06. If you plan to create a terrain from the contours, then I would suggest TIG's Hidden2Layer.rb (version 1.2) script and use it as mentioned here: http://www.sketchucation.com/forums/scf/viewtopic.php?f=57&t=8726 . In summary, the procedure is this: A. Import the contours. B. Triple click on a contour of segments and WELD. C. Then right click on it and choose the the BZ context option of PolyLine Divider. Do note that for some reason (I think it has to do with the number of segments), the BZ context options may not be available; in that situation then bisect the weld segments into smaller lengths (see the mini-tutorial, Step 2). D. After completing Step 3, then you may want to weld the "segment-reduced" contour path back together into one continuous polyline.[image: Fygv_BZContextMenu.jpg]Mini-Tutorial for BZ method of segment reduction UPDATE: If Weld.rb does not work on all segments of a contour, try a selecting a smaller set of segments. OR, try selecting a few contour elevations (use one of SU's side views to do this), copy and paste them into a new file (or create a component out of them and then do a context menu Save As to create separate .skp), then try to weld, etc., then repeat the process for another set of contours; finally paste these back into one file. Otherwise, have the segments simplified by the surveyor in AutoCad first, or have them subdivide the one DWG file into 4 or more subfiles.

I'll add this this evening. Thanks. Todd

Thanks a lot. Forget about create group from slice

There is, but it's rather complicated. You need to use a series of Sketchup.send_action("pageNext:") commands until the Sketchup.pages.selected_page is the one you want to have active. EDIT: It appears there IS a pages.selected_page= method, that is undocumented. The method makes it UNcomplicated, but the undocumentedness re-complicates things

After assigning the attributes to the definition, did you save out the definition (rather, an instance of it) to an external model?

I'll have to check - I may have hard-coded an expected (PC) path that will be different for Mac. Regardless, the script should work, even without the cursor change.

Yup curvestitcher was the one I was thinking of. Thanks for the great script Rick.

That's cool. Well, I won't be getting any work done for awhile now. I'm going to be playing with this instead.

it's a given there's no hurry Fred... ..i'm already glad to get an answer to my question - (18 replies to my languishing post in fact) cheers!

If a possible application would be contour maps generated from grayscale images, then it's been done. Check the SketchUp Pro user group boards, and look at some OLD ruby stuff. I can't remember the names of things, but TBD had one, and maybe Dider had something.

Flatten.rb is a commercial script and should not be just "put" (copied?) from one jackass' folder into another one's. So please, make sure you are not breaching any copyright conditions.

Hi Again, Does anyone know anyone that they think could help? Cheers

I wouldnt want to image the maths involved in offsetting something on a curved plane, offsetting a planar line/polyline is what I was trying to achieve... but since you mentioned offsetting a curve on a surface - that would mean offsetting a 3d curve - which could come very handy - for a lots of applications . If there is anything that could be done to help you with this development - let me know.

I've moved watkins post here, where you should be able to respond. Replys in the Depository should now closed.

For those interested in Windows-style dialog boxes (i.e. not Web dialogs), I had written a library Libtraductor.rbthat supports also language translation in dialog boxes and ease the checking of parameters (min, max, string patterns, ...). It also preserves defaults and previous values. I use it in Bezierspline and in JointPushPull (and actually in other unpublished scripts). Attached is the script, as well as a tutorial for programmers in English. Here is a snippet of the interface dlg = Traductor;;DialogBox.new title #Declaring fields, either string, numeric or unit-based numeric, or enumeration list; dlg.field_string symbol, label, default, validation_pattern dlg.field_numeric symbol, label, default, value_min, value_max dlg.field_enum symbol, label, default, enum_hash #Showing the dialog box; Hash_results = dlg.show hash_initial_values to drop in Skecthup Plugins folder Tutorial for Ruby script programmers

You're welcome. There is at least one list of these send_action numbers. I found one on the Google Pro Group.

Not that I am aware of.

I have updated the script to make it remember values between calls. http://www.sketchucation.com/forums/scf/viewtopic.php?f=180&t=8917

Hi Burchard Thx for the heads up on xnview in SU Very slick and a great idea. dtr
