I have a Creality K-1 Max. Most of the time my Skechup files slice properly. However some times they seem to slice showing a complete block of material.
I have attached the SKP

If I go back into the file and play around and either explode the file or group the file it will sometime work.
I know that there is something that I am missing. Can some one help me please?
Most of the faces in your model are incorrectly oriented. There should be no exposed blue back faces in the object. The blue back faces are to be oriented toward the print media while the white front faces are to be oriented toward air.
Correct the face orientation by opening the component for editing, right clicking on a white face and selecting Orient Faces.
Are you expecting some feature where you’ve drawn the circles on the vertical faces?
I’m curious about your work flow because you really shouldn’t be ending up with all those reversed faces or the coplanar edges. Those features make it look like you are modeling too much in 2D before going to 3D. When modeling for 3D printing I tend to think about it in the same way the thing would be printed. For the initial 2D drawing I only draw in features that would get printed in the first layer. So that would be the perimeter on the print bed and any through holes. Features that don’t touch the build plate don’t get modeled at first. I drew your thing in that way. I didn’t include those circles that aren’t extruded in your object and I skipped the recesses on the far end. Note that at no time after the thing is first made 3D is there any reversed faces.
I really appreciate you help once again. What I am doing is creating a template for making rectangular burgers for Patty Melts. Round Burger put between two slices of bread leave to much bread around the burger.
I tried several times to print it with a group of 6 in one print, and it was close to the max of my machine and failed.
The opening on what will be come the bottom is larger than the opening on the top (the hope is that the burgers will come out easier).
So all of the boxes have the same interior and exterior dimensions.
The exceptions are Left and Right corners have extrusions to allow for lifting the entire unit.
All of the units need to snap together (much like a poor mans Lego). So I created the inside box with all of the circles to be certain they were all in the same place on every box. “THE MASTER”
The the process is that I would open the master and extrude the edges on the appropriate sides and either extrude or recess the circles so that they would match exactly when the unit is assembled.
I had a bit of and issue drawing the slop on the inside of the box which is likely the reason I lost track of the orientation. I didn’t understand the importance of the orientation.
What is the difference between “Revers Face” and “Orient Face”?
Cool project. Did you know the patty melt was invented here in Minnesota?
So you need to add a bit of draft to the inside of the box? You can do that easily with the Scale tool. Select only the edges of the opening, get the Scale tool, tap Ctrl to scale about the center and drag a corner handle outward a little bit.
As far as the circles go, if you want them to show up in the print you’ll need to either pull the faces out a little or push them in otherwise they won’t show in the print.
Sorry. I missed this earlier.
Reverse Faces flips the normals for the selected face or faces. If you select the blue faces and choose Reverse Faces, it will flip them around so their white sides are out. Orient Faces, flips the normals for other connected faces to match the one you’ve right clicked on. In the case of your model, Orient Faces is faster but you could do the other.
Is there an easy way to save these (chats for lack of a better term) so that I can reference then later and keep all of the videos as well?
You could click the Bookmark button at the bottom of the thread.
I am still working on the Patty Melt jig. I created 6 individual ones and glued them together. It worked but cleaning the glue residue is an issue.
So I created 6 in one unit. I needed to make some adjustments to the exterior dimensions to fit within my 300mm x 300mm max.
My interior wall widths are 6mm ad 7mm respectively. I want to create a maximum slope from the top of the unit to the bottom in hopes that it will allow the burger to slide out easier.
I am trying to create the slope 2.9mm on all boxes. This should give me a flat bottom of .2mm on the 6mm width walls and 1.2 on the 7mm walls.
I place the cursor on the mid point of the rectangle and press the control key I get two choices “Red Scale about opposite point” or “Red Scale about center”,
I have a attached a video and the file.
Tap Ctrl to get the Scale About Center option.
Or drag inward depending on which side you ware working on.
BTW, you need to fix the bottom. It looks like you still drew too much in 2D before you started making it 3D.
Take a look at the steps here.

A. Outline the bottom of the frame with the holes.
B. Extrude to the height of the flange.
C. Offset the outer edges to the width of the flange.
D. Extrude the inner part to full height.
E. Scale the top edges to add the draft.
Perhaps I am confused. When I am scaling, it is my understanding if I want to pull it back 3.25 mm I should be able to enter that and press enter. It seems if I go much over 1.1 it completely distorts the pull.
If you want to scale and add 3.25 mm to the dimension you need to included the units instead of typing a scale factor. Type the desired overall dimensions not just the 3.25 mm, too. Of course you can’t scale the rectangle to larger than the surrounding geometry without causing distortion.
