AHTOH - yes, I have learned my lesson - not to use TIF files. I appreciate you sending the sink file, but this is not the shape I am looking for. I could easily create what you have attached, but the shape I am trying to create is more complex and certainly not symmetrical from front to back. I was able to get what I needed using other software. I have always found FormZ too stringent when it comes to what is and is not allowed when performing certain nurbs operations. I can understand the need for these "rules" to ensure accuracy, however, sometimes you just want to turn out a shape. Thanks again to all that replied. Kevin

setz - thanks for the input. I would prefer to use subdivision surfaces if it was possible to draw with faceted geometry in FormZ since version 7. I find the results quite messy.

Chris - thanks for the reply. Yes, I tried your method 1 above by sweeping a 1" radius along the boundary edges. The pieces split okay, but now I'm finding it impossible to generate a blend between the newly created edges. I get an error that states something to the effect of "can't create nurbs blend between these edges". So, I start all over extracting edges and recreating the surfaces via boundary nurbs, lofts, etc. These newly formed nurbs surfaces won't blend either. Nothing has ever come easy as pertains to nurbs for me in FormZ. I give up at this point. Fortunately, I have other tools at my disposal that simply work!

TEST IMAGE 02 Thanks Andrew for the advice and the model. I think I figured out the attachment process. It cannot be a TIF file or it gets attached instead of embedded. The JPG here works just fine. I realize I could model this using booleans and rounding, however, I'd still like to know how it could be done with nurbs. Thanks again for your input!

TEST IMAGE sink_nurbs.tif

Thanks Andrew. However, this only attaches the image, I think. I am trying to embed an image so that it appears with the text.

I don't use this forum that often. How in the heck do you insert images in your post? Not very obvious to me!

I'm modeling a sink. I have three nurbs surfaces as shown in the attached. I need a 1" radius along the segment outlined in red. I have tried stitching the three nurbs surfaces together and using the round tool without any luck. In Rhino it is possible to offset an edge in order to split the surface a certain distance away from an adjacent surface. I could thereby use the nurbs blend tool to create my radius. Is there any similar function in FormZ. If not, how do I go about getting the rounded edges I need. The file is also attached. Much thanks! Kevin sink_nurbs.tif sink_nurbs.rar

vbaran - yes, that's it, however, it doesn't align with the paths. No matter what I do with the object axis or the interactive controls, I can't get the alignment I need. Chris - vbaran'd example above shows that it is possible for the 2 path sweep to provide the two radii. Now if only I could get the result to align with the paths.

Chris - thanks for the input. Your method is similar only with the use of Nurbs. I swear at one time I was able to get this shape using 2 path sweep.

Des - I didn't think of rounding a 90° corner after the sweep. That should work. Thanks for the suggestion.

Thanks for the replies. I wasn't getting email notifications. Yes, sure the axial sweep works but that doesn't change the radius from rear to front of the profile shape. Not sure why many are saying the shape is impossible as this model is to represent a granite counter edge. I haven't been able to use the 2 path sweep effectively since V6.

How do I get the 2 path sweep to work? The source shape never aligns with the paths even trying various positions for the object axis. When done interactively, I can't get it to align precisely either. Please advise - file is attached. 2PathSweep.rar

Andrew - Thanks for the reply. I was finally able to figure it out late last night. I opened a newer file and reset all prefs and project settings.

I am unable to open FormZ or any associated files as I am continuously prompted to open library files (.zlb) that do not exist. I loaded some old prefs to retrieve some export settings and I suspect this is what started the problem. How do I go about getting this resolved so that I can actually use the program?
