I'd like to create a hyperbola as a formula curve. Here's the data: Var Name = t Tolerance = 0.1 Start Value = 0 End Value = 43 X(t) = t Y(t) = sqrt(sqr(10.184)+t*t)*2.546/10.184 When I hit either Preview or OK, nothing happens. What is wrong? (Edit) I messed around and found that if I replace sqr(10.184) with 103.714 and 2.546/10.184 with 0.25, it works. I'd rather be able to define a = 2.546 and b = 10.184 as parameters and then Y(t) = sqrt(b*b+t*t)*a/b How can I do this?

I'd like to create a formula curve that is driven by parameters. For starters, I created 3 parameters: a = 1.8mm theta = 45deg f = a*(1+sin(theta)) (the calculated value is correct. yeah!) Now I create a formula curve Var. Name = t Tolerance = 0.1 Start Value = 0 End Value = theta <<< Is this permissible? X(t) = 2*f*sin(t)/(1-sin(t-theta)) <<< Is this permissible? Y(t) = -a+2*f*cos(t)/(1-sin(t-theta)) <<< Is this permissible? Just so you know, I've tried this in SolidWorks and it bombs. I'd love to see IronCAD beat SW.

I'm trying to import a STEP file generated by Solidworks. It has 9 bodies and 9 Breps in it. When I right-click on a body in the system tree, I get an option to associate a body with a BREP. However, when I do this, all I get is a SaveAs dialog. I will request an x_t file from the Solidworks jockey, but that is just a workaround. It would be nice if this feature were described in help. sight.STEP

I have a STEP file that I manually created, so it probably has some errors. When I try to import it, I get a messagebox saying that STEP import failed, but no details. I have the "Display error messages during import" checkbox checked. Is there a log file for importing or somewhere else I could look to figure out where I messed up? Other than that, does anyone know where I could look on the web for a STEP file error checker? TIA.

Yes. Please send it to the ER

Every time I start Inovate, I get a blank window. To get to my Most Recently Used file, I have to close the blank window, click to discard changes (even though there aren't any) and then open my file. If I don't discard the blank window on startup, I have to do it at shutdown. Is there an option somewhere that allows me to either open my MRU file on startup or at least open nothing?

Thanks for the tip. I tried a second time and got about the right size, but the file was corrupt. A third try did the trick. V2009 is working well on Win7.

I'm running Win7 64-bit, but when I try to run Inovate2009XG64.exe, I get a message telling me that "The version of this file is not compatible with the version of Windows you're running..." "Run as administrator" does not fix this problem. The only other clue I have is that the file size is 283,552KB, which is only half of the advertised size. Do I just need to re-download?
