  1. I have found that if you move either the proposed or existing dtm symbol, say to see the proposed next to the existing dtm symbol, the cut and fill will not work. But I have also encountered numerous other inexplicable problems with the new dtm method that nna tech have not been able to explain even after numerous emails to them.

  2. Under VW Help/9.5.0 Documentation Bulletin there is an explanation of the trim command. It seems, just as you have stated, the trim command works only for lines and walls (not rectangles, polygons, etc.). I believe you have to use the trim tool on rectangles and polygons.

  3. I tried following the sample makeattachrec.vss, (www.nemetschek.net/support/custom/vscript/example.html "Attach Record to Object") to attach and assign record fields to a symbol. The record and fields were created but nothing is assigned to the fields besides the default info. I then tried running the example script with its associated drawing and the same thing occured.I'm using VWA/L with Win 98se.

    Is there something I'm missing with this example?

  4. I have tried creating dtm's with relatively large numbers of vertices (1000's). The progress monitor seems at times to stop, however the dtm is still being created. I let one such large dtm run while I ate lunch and sure enough it was finished when I returned. How many vertices or stake objects are being used to create the dtm?

  5. I was wondering about the same thing. The z field seems like it would change the position of an object in 3d space, but since structural shapes appear to be just 2d objects they can only appear in plan view, so why the z field? To make the object 3d I had to ungroup the symbol and then extrude it.

  6. I have experienced the same difficulty. I have been able to get the paste as picture to work as long as I use the scale command to resize the bitmap to fit the desired area. Do not drag a corner as this will cause all kinds of cells to be improperly positioned.

  7. Valerie,

    A user provided this vectorscript sometime ago, I wish I could remember his name. It works with 8.5.2, I'm not certain about 9.0.1 and Landmark.

    {The script begins below, this is a comment line}

    procedure coord;








    PutFile('Output file', ' ', ofile);






    while obj<>NIL do



    if (i=9) then begin













    {This comment line ends the script}

  8. A few things you may want to check:

    Did your 3-d polys all have the correct z value after running 2-d contours to 3-d polys? Check by selecting 3-d polys and looking at the z value in the info palette. Also check to see if the range of z values match the range shown in the settings dialog box. If not you may need to change the scale of your 2d poly layer to more closely match the map you are tracing the contours from.

    Do any of your 2-d contours cross? Run the DTM/check 3-d polys menu command to make sure.

    Are some of the 3-d polys too close together? Run the filter 3d polygons tool to check.

    These are a few things I check if a DTM does not work.

  9. The textures are jpg files. I dropped them into a photo editing program, cropped out borders, and then saved them as a jpg file. Then create a texture using VW resorces/new/texture/create/image/etc.

    These are low resolution files. It seems to me a lot better to photograph materials with a digital camera or scan catalogs to get better quality images to use for textures. You may have problems with overlapping but no more than you will with the textures from this web site.

  10. If you are trying to cut a fillet or round the corner of a solid this works: 1.) Fillet a 2-d shape, a rectangle, and extrude that shape to a length that will be great enough for a later subtraction from the 3-d shape. 2.) Create another 2-d shape that overlaps the filleted extrusion just created(the filletted corner of the extrusion). Extrude this shape the same as that in step one. 3.) Perform a model/subtract solids on the two extrusions you just created subtracting 1 from 2. 4.) Finally, use model/subtract solids and subtract the result of step 3 from the original 3-d object.

    I have found at least one other way to cut fillets but this method worked the best for me. Please, if someone knows a better way let us know.

  11. There shouldn't be a problem unles there are x,y coordinates having more than one z value. I would hope that vw landmark dtm software will allow filtering of data, but with vectorworks 8.5 I have not found a good way to do this. What I have done is split dtm areas in half or quarters, run dtm's on each subset of points, and continued to split a problem subset further until I could zoom in or otherwise examine the points as a text file or excel spreadsheet to determine what loci are causing problems.

    This is not a good way to solve the problem and I certainly hope that one of the improvements in the landmark dtm is that there will be some type of filter. Unfortunately, Nemetschek will not tell me what the improvements are to the dtm software. I have written to them and all they provided was a pdf file that does not answer what the improvements are, it simply states that there are improvements.

    My email adress is marc@digisys.net. If you would like you can send me the text file and I will give it a try.

  12. You might want to check your z values and make an adjustment.

    You say that the z value range is 418,557m and 430,000m. Are the commas decimal(as in Europe)or thousands separators. I'm not aware of vectorworks being able to handle commas as decimal separators, unless European versions have this capability. If these values are being recognized as 418.557 and 430.000 thousand meters than you are trying to create a dtm with a 11.443 thousand meters change in elevation or roughly 36,617 feet. I don't think this is practicable.

    If the commas are decimal separators then I would suggest you change them to .'s instead of ,'s (unless your version of VW can recognize ,'s as decimal separators).

    The only other thing that I can think of that may be giving you problems is that you may have 3-d loci that are too close together in the x-y plane but have extremely different z values.

  13. Did you use add to give the working plane a name and to permanently save it? You can scroll between working planes that are automatically saved but I have a hard time remembering which ones are which unless I give them a name. If you do give them a name then double click on the name rather than using the right left arrow buttons. There shouldn't be a problem returning to the ground plane if you double click on it. You can't, at least I can't, get back to the ground plane by using the left right arrow buttons.
