Expression problem

In the attached spreadsheet, I have the following expression in cell B6: = (360 - Arc) - 2 * atan2(Wid; Rad) This doesn't parse, claiming "Incompatible units for '-' operator) The result of atan2 is in degrees; I presume it doesn't like the simple number (360-Arc) in the expression. I didn't see any...

Re: multi-transform for different material

Ah, ok, Thanks. That all seems consistent, at least!

Re: multi-transform for different material

You could have modeled the windows in their own body This was the original problem -- I can't model the windows in their own body because they are not contiguous. The reason for attempting to cut them from the original body was because of that issue. There's clearly something I don't understand her...

Re: multi-transform for different material

Sorry for the slow reply; stuff happens... In the attached file, the "Cut" would be used to produce an .stl for printing just the windows, and the "PolarPattern" object is the overall object with holes for where the windows go. Assuming I later want to add more detail to the overall object, I need t...

Re: multi-transform for different material

Doing a part cut worked, thanks both for the info. I erroneously assumed that since the remainder from a cut would *look* disjoint it wouldn't work either, but now realize the remainder part contains the whole it started from. However, I don't really want the window pieces I put in (so I could have ...

multi-transform for different material

Designing a part with a clear window which is replicated. The window needs to be a separate body so I can output a separate .stl for printing with a different material. When incorporated into the main body it will all be one piece, fused by the printing process. However, I can't make a polar (or any...

Re: string length?

Thanks, Draft ShapeString
Is there a way to use a python expression as the value of an existing property in the property editor? I tried but the expression parser doesn't even like the starting "App"

string length?

Is there a way to get the length of a string created in DraftWB? There is a "Length" property which is the height of the string, but no length. I understand the length depends on the height and the font, but once those are chosen is there an expression to retrieve the length? I'm trying to center a ...

Re: simple folding in Part or PartDesign wb

Ok, calmed down a bit. But it really annoys me if I invest considerable time to find things out and those asking for help simply ignore it. I understand, apologize, and really, really appreciate you taking the time to help me understand this. FWIW, I refreshed my browser page prior to that first po...
