Hi Tom Luigi here from SNC-Lavalin. Hope you are well. I was wondering if the developer of Quicksurf had looked into the issues, detailed above, I had brought up 2 years ago or so? There are quite a number of Quicksurf users at SNC and the the above issues reduces their efficiency and production capacities. The workaround we use is slowing down users. Is a new version available? Resolution of these issues would help us greatly. Thanks for a quick reply. Luigi Pradolin SNC-Lavalin Inc.

Hello Tom, I have another request related to quicksurf function qsi_bound. Right now if you call the function with read, a dialog box pops up in order to select the file name. User intervention is required. Is it possible to modify the function such that the file name can be passed as an argument. In such a case no file section dialog box would appear. No user intervention would be required and a true automated (batch) run can be carried out. Is a new version of quicksurf to come out in the near future? Thanks, Luigi Pradolin B. ing., M. ing.

Hi Tom, I discovered a new problem with QuickSurf. When all the values, for which contours are to be plotted, are identical the resulting QS plot is single uniform color. This is correct. However, the color plotted is not correct. QS always plots the color corresponding to the lowest interval no matter the values. If I select only one data point and offset its magnitute ever so slightly, the resulting color of the contour plot is correct. Can you look inti it and pass it on to the developer. Thanks Luigi Pradolin SNC-Lavalin By the way, do you know when a new version of QS may be released and which corrects all the issues I brought up?

Hi Tom, Quck question concerning contour plots using QuickSurf. I have an AutoCad file with the contour data (X, Y coordinates and a Z value) stored as XDATA. Is there any way, after I've extracted the XDATA, to pass it on to QuickSurf in memory without having to write it to an ASCII file and then read it in? If so, what is the function name or proceedure?

Hi Tom I hope it is not too late to add another request to the the list in my April 16 email. This involves the specification of the "Surface Color Intervals". At the moment the intervals can only be specified manually via the "Surface Color Intervals" dialog box. Is it possible for the developer to create a lisp programming function which would allow the specification of these intervals. This lisp function would greatly enhance the automation we are developing for the use of Quicksurf with AutoCad. Thanks for passing this request on to the developer. Luigi Pradolin B. ing., M. ing.

Hi Tom, Thanks for looking into this. However, I have discovered 3 additional issues with QuickSurf programming functions. Here is a brief description on each one: 1. The QS function "qsi_qsl" has a 128 character limit on the file name. Can this limit be extended so as to be compatible with Windows limits. I some cases the filename lenght with path exceeds 128. I suppose it may be a good idea for the developper to verify all QS functions which deal with file names and correct any file name length issues as this one. 2. When you issue the autolisp command (c:dsop) and the "Surface Management" dialog box appears, the X at the upper right hand corner of the dialog box does not work. Clicking on it does nothing. Pessing the escape key on the keyboard does nothing as well. The only way to close the dialog box is by clicking on the OK button. This would signify acceptance and may not be what the user wants to do. Can the developer look into this as well. 3. The last item concerns the use of the QS function qsi_grd and the plotting of the legend is set to ON. At the moment there is no way to transmit, via the function, the coordinates of the legend (upper and lower corners) nor the size of the text. When the function is called user intervention is required for those 3 items and cannot be automated. Is it possible to add 3 additional arguments to qsi_grd in order to handle the situation where a legend is required to be plotted with no user intervention such that full automation can be realized. Thanks, Luigi Pradolin Eng. SNC Lavalin Inc.

Hello, It would appear that the Quicksurf programming function qsi_lcmap does not accept long file names. It seems to have the old DOS 8.3 file name limit. Can you confirm my observation? If confirmed, can the function be modified so as to accept long file names? Thanks Luigi Pradolin, Eng. SNC Lavalin Inc.
