  1. Thanks everyone for the suggestions. I'll give the wall reshape tool a try.
  2. I rarely use the architectural features of VW, so I'm wondering how easy it is to create gable dormers on a 1-1/2 storey house. I looked at the various examples for drawing dormers, but they all appear to be wholly part of the roof. As typical for a 1-1/2 storey house, the windows extend from the 2nd floor exterior wall into the roof (see attached elevation sketch). Note that I'm using VW 2016 fundamentals, not Architect. However, the roof object and roof face features are available in fundamentals. This is for my future vacation home that I want to have reasonably well laid out before taking it to an architect to do the detailed design. So, It's not absolutely necessary for me to get it perfect, but I'd like to get it as good as I can with reasonable effort.
  3. Yes I did. The problem goes away when the resolution is above about 300 DPI, but then this results in a much larger file size than I would like. So, I have to post process the file to reduce the DPI back to about 75. These are diagrams that I post on the web, so I prefer to keep the DPI close to screen resolution. For some reason, your 150 DPI export looks a lot better than mine. At 150 DPI, my arc was composed of only 8 line segments and consequently looked really bad. It may be because my arcs were 270 degrees compared to the 180 degree arcs in your example. The attached export file shows what I get. Note that the figure on the left without the arrowhead is very smooth. The others with the arrowhead are very rough.
  4. Thanks. I eventually found those settings, and changed them. As I mentioned in my last post, the problem only seems to occur for arcs with arrowheads when you're exporting at or near screen resolution (72-150 DPI). So, it's rather obscure, but still annoying. I've submitted a bug report on it. The workaround for now is not to put an arrowhead on the arc, but rather make the arrowhead as a separate object.
  5. Nevermind. I realize that I did have the resolution set correctly. This turns out to be a program bug. If you export a circular arc it works fine, but if the arc has an arrowhead on one or both ends, then it exports as a very coarse segmented line. I'll post a bug report on this.
  6. Thanks, but I have no idea where to find the settings that you've mentioned.
  7. Since upgrading to VW2015, I've encountered a problem when exporting image files. The resolution of circular arcs is extremely low. They are represented as a very small number of line segments. For example, an arc of 270 degrees is represented as a series of 9 straight lines segments. I've searched through both the Vectorworks and document preferences, to find export resolution settings, but can't find anything that fixes this problem. Prior to this, I was using VW2009, and export resolution was very high.
  8. Nevermind. I did a bit more digging and realized that I should have been doing a sweep rather than an extrude along path. It now looks the way I want it. Even so, the glitch when doing the extrude along path appears to be a bug in Vectorworks.
  9. Thanks for replying. The only difference between what we did is that when I created the helix, I used a starting angle of 90 degrees. I have now found that I don't get the twist at 0 and 180 degrees if the helix starting angle is 0 degrees. However, that creates another problem. When the starting angle of the helix is 0 degrees, I can't get the surface of the extrusion to be parallel to the axis of the helix. I think you will find in your own example that if you rotate it into a different view, you will see that the surface has a slight angle to it, as can be seen in the following image: I've attached my original files, saved before the extrusion and again after the extrusion.
  10. Hi, I'm trying to extrude a thin rectangle along a helical path. It appears that as the extrusion hits the 0 and 180 degree points on the helix, the rectangle twists around (see image below). This is with the "lock profile plane" option checked. If I leave it unchecked, then the profile rotates continuously through the extrusion. The helical path was created using the helix creation tool. Any idea how to fix this problem?
  11. Which version of OSX are you running on your Mac? Do the files have a .vwx extension? I've had similar problems transferring version 11.5 files from my old Mac to my new one unless I added the file extension before transferring them to the new computer. In my case I believe it was an operating system problem, OSX 10.5 (aka MacVista) rather than a Vectorworks problem.
  12. The phase symbol is the letter phi, ?, not theta. You can use a symbol font, but it's available in regular fonts as well if you know the correct key strokes (on the Mac it's available in all normal fonts, and it's simply option-o or option-O for lower or upper case respectively). That's all I do for the phase symbol on my drawings.
  13. Correction: SetDefaultEndMarker function visibility parameter is correctly set to TRUE just before drawing the one and only line (an arc actually) that requires an arrowhead. However, it fails to add another SetDefaultEndMarker function to change the visibility back to FALSE afterwards. Hence all other lines which occur afterwards in the file are incorrectly drawn with arrowheads.
