It's good to know about the (hidden) option to fill the holes when copying and pasting quilts, but I do think that the remove function seems more appropriate. It was mentioned in this old thread that the function doesn't work on "edges", but seems Creo is more capable now.

I am trying to fill a hole on a complex surface. I use curves to chop it up and boundary blends to fill it in. However the tangencies are not perfect and I can still see a small seam. Any suggestions would help.

I need help with something I am trying to do in my drawing. I am using Creo 6.0.

Let me start by describing what I am trying to achieve. I have an anodized sheet of aluminum that gets cut and then has an engraving operation done in the middle of the part to show a patterned design, a logo, and text. This is done with a laser which requires a DXF file as an input.

I have the outside geometry defined by the part, which will become a tool path for the laser to cut. In the middle of the part I have a sketch showing an array of rectangles, a sketch showing an elaborate logo, and another sketch with basic text (using Creo font font3d). All of these features need to be filled which I have done except for the text as I cannot get the text to fill. In the part I filled the other two features using the "Fill" feature from the surface menu. These need to be filled because this is how the laser knows to remove the area inside the defining geometry and not just the outline.

The problem I am having has to do with the output file. When I convert my views to "No Hidden" lines the fills disappear and I simply get the outside bounding geometry in my output DXF. None of the fills show up. I have found that I can get the fill to show up in the drawing and the DXF if I use the Sketch>Edit>Hatch/Fill command within the drawing itself. However, this is extremely tedious because I first have to sketch the geometry in the drawing. This is not a viable solution as it is very time consuming, especially with the logo, and it will not update if I change any of the sketches in the part.

I really feel like there is a solution I just have not come across it yet. Any thoughts or suggestions would be greatly appreciated.

At least in Creo 4.0 drawing module, there seems to be an easy way to generate an x-hatch object which can "paint" model's surface or quilt with a pattern or solid-fill. This is different from using drawing-sketch "Hatch/Fill" function you mentioned, in that the hatch does not use draft entities but it uses the model geometry directly.

We have done "revered engineering" on a water-vaccumcleaner. So we built the model in creo and when we import it to simulation cfd 2017 it will not find the inner volume (have blocked inlet and outlet), And tried without blocking and i used Void fill but i get this massage: ((((an insufficient number of surfaces were defined to yield additional parts)))))

Before i have done a basic flow analysis so i have used the program a little before, but i cant find out why it will not make the inner volume and not even when i open inlet and outlet and make a void surface for inlet and outlet instead, still void fill wont work....Im looking in my creo cad model, but i dont see any leaks/holes/cracks

Thanks for reaching out on the forums! This issue shouldn't be too hard to resolve. Here is a great post that details a pretty creative solution. Give this a try and see if you can resolve the problem. If you are still facing problems, please upload your CAD geometry and I can take a look at it.

Methods: Claims-based analysis of commercially-insured youth with T1DM included in OptumLabs Data Warehouse between 2011 and 2021. Glucagon fill rates and costs were calculated overall and by formulation (injectable, intranasal, autoinjector, and pre-filled syringe). Sociodemographic and clinical factors associated with glucagon fills were examined using Cox regression.

Conclusion: Roughly 30% of commercially-insured youth with T1DM may lack access to unexpired glucagon, with significant disparities among Black and low-income patients. Health systems, clinicians, schools, and caregivers should work together to ensure children have reliable access to this critical medication.

Yes, that's an option, the problem is when the surface you want to project to is curved.
I've reached to a solution that is hatching the text from the sketch, then you define the hatch lines so close to each other, that the appearance is like if the text was filled. I know that this is not the same, but it's a valid solution for me.

me funciono perfectamente, para los de espaol, lo que el explica es: Con esas instrucciones, AE va a crear un frame de referencia en formato PSD (como el dinamic link esta roto) en la carpeta de destino se creo un PSD, el cual al abrirlo con click derecho y seleccionar la version de PH que tengas, ahi puedes ya trabajar tu frame de referencia de ''LLENAR SEGUN EL CONTENIDO''

Data comes as a solid in if I use a low accuracy model template, but it seems that soon after things go wrong because boundary blends don't work as the selected edges do not form valid loops, and projected curves end up with missing segments or little segments going back on themselves.

The only thing that will work is to rebuilt the entire surface with sections and reference points for either a blend or boundary blend. You can use exisiting surface to characterize the new surface, but in general, I would try to make it independent. In IDD, separate out all the affected surfaces so they can easily be removed for the solidify process. Then determine the best way to rebuild the existing and missing geometry.

I can't open native Solidworks file, but i performed a reflection analysis on STEP coming from Solidworks. It's ok. Just a zone with no tangency but i think it could coming from STEP conversion. It seems that solidworks and nx manage surfaces with no respect of patches of near surfaces. And that's good.

Let me also bring up the terms "Unite Technology", and "Flexible Modeling". Though, these are the bells and whistles we are not gonna be able to use on some (or maybe most) occasions, just because of the way Creo treats the input data.

I guess you realize it doesn't have to be only STEP or IGES data coming in. It can be data from say Catia directly, which Creo Parametric treats in alot worse manner than STEP data during the import, meaning it introduces alot more bad geom, gaps, etc.

STEP, IGES or any universal data format type is just a middle man in the process of data transfer. It's an unnecesarry copy of the geometry, that serves only as a link between all of the CAD/CAM systems out there. For PTC to eliminate this link out of the process they will have to make sure the software can easily deal with data such as posted by the OP (Blue).

There's no complete tangency on Rohit's step. No hidden visualization with white edges shows no tangency edges. I improved a little with IDD, but that tool can't force tangency anywhere. Anyway to repair a 3D file is good. For manufacturing no.

I have no excellent skills in ISDX module, but i reach a complete filling of entire surface with tangency continuity. I rebuild surfaces. Expecially near the hole, geometry was very poor. IDD isn't a perfect solution. I think that for guys of reverse enginering filling this hole is a joke. Sure it's not a 2 click work as in other software. I attach Creo2 and STEP file. There are little distorsions on my work, but i'm not a specialist.

I don't think so,In advanced surface,Creo is weak compared with NX.Creo just provide IDD TOOL to fix input data(igs/step).It's a limited capabilities tool. From Proe to Creo ,do you see the advanced surface be enhanced?

Ok, here's the latest and last stab at it. The surface is made with a VSS and with the exception of the spine, all the trajectory curves are conics with the rho vale for a perfect 90deg arc (use the sketcher section relation: rho = sqrt(2) - 1). If I used conics in the section of the VSS, it gave some funny artifacts at the curved edge, so the section was an arc driven by the 3 spines. I think this is a LITTLE better, but I think this is also the practical limit to Pro/E without the ISDX package. The grey surface is Pauls first STEP file, the bronze one is my latest. Have fun!

Extrude the arc on the right up to the arc on the left. Next, revolve 1/2 of the arc by creating a new sketch on the lft vertical plane, 180 degrees. Next, mirror that new endcap to the right side using the center plane. Next, select the center bit, and the the two ends (with CTRL) and click "merge"

Looking at the Step file, the vertical section has a larger radius. In this case, you want to use some intelligent blend options along with control of the edge tangency. If you must duplicate the original exactly, you can use the Step file to obtain some of the critical information such as slopes and end angles. In essence, you have to figure out how the original was generated.

You can obtain curves from the original in one of several ways. I was building datums and creating sections. from the sections, you can generate datum curves "datums>Curve from Cross Section". The footprint can be projected from the surface to a plane.

SolidWorks tends to make a lot of assumptions when creating features such as this. I have had the fortunate experience in doing exactly what you are trying to do here with SolidWorks. It really is a handful to manage. Creo can do this but certainly not as straight forward. You either allow assumptions with tweak features or you define every aspect.
