allan downes Posted July 27, 2017 Share Posted July 27, 2017 (edited) Thanks, indeed to buy some of the softer solvent anyway so switching to laminated 20thou should be fine for most of my plans. Just need to stop the warping of laminations. So many potential ideas going through my head at the moment I'm still unsure as to what I will actually do with it first! As for the heat, I'm dreading coming back to Sevilla in 2 weeks time! I'm going to melt! Just how hot is it out there,Rich ? In Fahrenheit please. Cheers. Allan. Edited cos spelt Fahrenheit wrong !

RMweb Premium Ray H Posted August 1, 2017 RMweb Premium Share Posted August 1, 2017 Ray - what version of Inkscape are you using? I found (post 1963) that the change of resolution for pixel units in the newest version (0.92) of Inkscape gives the wrong size drawing when opened in Studio, so I have had to revert to version 0.91. Mick Mick I wanted to cut some outline shapes of (Word) special characters - diamond, circle, triangle and square - so that I could ensure the relative sizes were all the same. I found that I couldn't create these characters in either Inkscape or Studio so resorted to Word. I printed out the characters, scanned the print as an image, saved it as a .jpg file which I opened that in Inkscape. I saved it as a .dxf file from there so that I could open it in Studio - which doesn't appear to have a facility to scan images. I tried several times to create the output file but although the Portrait would do a test print it wouldn't print the special characters. I then realised that what I was trying to cut were the scanned (relatively) blurred and infilled shapes which I doubt the Portrait liked. I went back to Inkscape and copied the outline of the characters on a separate layer and saved that. Studio opened that version ok but the data was enlarged when it was opened. In the end and in complete contrast to my earlier experience with size differentials, I had to change the pixel measurements to millimetres to restore the original character size. I've just tried re-opening the earlier window test file in Inkscape and have noticed that the measurements in that file were set to pixels although I don't recall changing them. It does seem that if the Inkscape drawing measurements and the saved .dxf file measurement settings are the same type, files created by the current version of Inkscape import into Studio OK.

MickRalph Posted August 1, 2017 Share Posted August 1, 2017 I will have another look, though I use the Designer Edition of Studio (thus opening Inkscape SVG files direct), so I don't have to do the intermediate stage of saving as a .dxf file.

RMweb Gold The Fatadder Posted August 1, 2017 RMweb Gold Share Posted August 1, 2017 How accurate is the silhouette at cutting small radius curves? One possible application I have been thinking about over the past couple of days is for the prototyping of laser cut glazing. My logic is to draw up a window in cad, and use various radius curves trial and error in order to cut a plastic or card blank to fit the window. Then once the design is finalised the drawing can be sent off to a laser cutter to commission a batch of the complete windows. At the moment I see there being a considerable additional expense sending off lots of small batches of window designs with slightly different radius corners in order to find the correct match for the model. All of which could now be done at home (assuming the cutter can produce a curve of sufficient accuracy) Link to post Share on other sites More sharing options...
RMweb Premium Ray H Posted August 1, 2017 RMweb Premium Share Posted August 1, 2017 Rick I would suggest that it is extremely accurate once the artwork has been set-up correctly. It will only cut to the drawing. There may be issues with compatibility between the various software packages, but I'd say that those aside - and you probably gets what you pay for software wise - there should be no worries about accuracy. I'm puzzled why you would want to use a cutter as an intermediate stage. Surely it is the design software that determines issues of accuracy. Presumably you will be working from a drawing to construct the building. Can you not use a line to determine the aperture to be cut in the body of the building and then use the same line as the base to design your window from or have I missed the point completely?

RMweb Gold The Fatadder Posted August 1, 2017 RMweb Gold Share Posted August 1, 2017 I think the issue lies with my ability to accurately measure the radius of the window corners (rather the the x and y dimensions). From previous conversations with manufacturers of laser cut windows, I have been told of this trial and error approach to finding the radius. But this would be very time consuming (and expensive) when you don't own a laser cutter. I probably should have added the context, in that I am looking at things like glazing Mainline Collett coaches) Drawings will be dxf in Autocad Link to post Share on other sites More sharing options...
RMweb Gold Stubby47 Posted August 1, 2017 RMweb Gold Share Posted August 1, 2017 If you can accurately cut the glazing using the Silhouette, then why then use laser cutting ? if you have an old coach window, try spraying paint onto a piece of card, or similar, through the window which will act as a mask. Scan the resulting pattern and resize to a known dimension (such as the width of the window opening). You should then be able to draw the correct radius curves for each corner and send to the cutter. 1 Link to post Share on other sites More sharing options...

RMweb Premium Ray H Posted August 10, 2017 RMweb Premium Share Posted August 10, 2017 That's clever. I've experimented a bit more. I've made up a couple of station running in boards. I've used several thicknesses of 20 thou plasticard and laminated them together. The outer layer on each side is an overlay for the posts only and the whole thing has a further piece of 20 thou fixed horizontally to the top and bottom of the board. This makes the entire assembly rigid. The Mark I version was drawn up using rectangles converted to lines whilst the Mark II version was entirely based around lines that I positioned using the X and Y co-ordinate input boxes at the top of the Inkscape window. The Mark I layers weren't completely "square" which meant that the laminations only fitted together one way round - something I didn't realise until after I'd started the assembly. The strips - post overlays, board top and bottom - were positioned between the posts below the board in the cut layout to economise on plasticard. These strips weren't as long as the board was wide which resulted in the basic frame being bent to snap the strips out on Mark I. I made the length of the horizontal cut lines for the strips the same length as the width of the board (with a vertical cut at the required length of the strip) and they were a lot easier to release when "snapped". I also made a station seat using laminations of 10 thou. The hardest part of that little episode was fixing the supports at 90º to the seat and backrest.

Biased turkey Posted August 19, 2017 Share Posted August 19, 2017 Thank you Rob Pulham for your opinion. The shells of the closed vicinal wagons are 3D printed . I designed the shell using the Sketchup software and sent the .stl computer file to Shapeways. 10 days later the 3D printed shell was in my mailbox. The material used by Shapeways to produce the shell is the FUD ( frosted ultra detail ). The "texture" is a defect inherent to the 3D printing technology. The part is printed layer by layer. But on a wagon shell at the 1/20 scale ( TT scale ) and seen from "the 3 feet rule" it is almost unnoticeable. The closed wagon ready to ship out beer from the Monrtfort brewery.

Biased turkey Posted August 30, 2017 Share Posted August 30, 2017 Using the silhouette portrait to cut ( part of ) scalescenes kit I needed a couple of coal staithes for my TTm scale layout. 1) I downloaded the free scalescenes kit R024 Weighbridge/Coal Office2) import the .pdf file ( page 2 ) in the Inkscape software Here is the result: 3) ungroup and delete what we don't need 4) Save the document as a .svg file ( using the "plain SVG " option ) 5) import the .svg file in the silhouette studio software ( designer edition ) 6) Change the color of the 3 white bars used as a guide to glue the edge of the sides . Change the outline color and the fill color of those 3 bars. It is necessary so they won't be cut in the cutting process. That is the result: One can see the grey lines where the cuts will be made 7) make a second copy of the staithe , add the registrations marks and print . 8) On the cut settings window , select the advanced cut mode select that grey color ( RGB 169, 160, 161 ) for the cutting. 9) start the cutting process and in about 1 minute all the cutting is done. 10 ) laminate and clue.

IMG_1746.JPG Jacques Hi Jacques. I really do admire your computer skills and only if mine were half as good but please forgive me for asking but why do you need a Portrait cutter to cut out a simple kit when you could have done it in a fraction of the time with a Stanley knife or similar ? Forgive me if I sound pedantic, but it did have me questioning it. Anyway, nice job all the same. Cheers. Allan. Link to post Share on other sites More sharing options...
Robin2 Posted September 5, 2017 Share Posted September 5, 2017 but why do you need a Portrait cutter to cut out a simple kit when you could have done it in a fraction of the time with a Stanley knife or similar ? Because when you have done it once you do it as many extra times as you like by pressing a button. Also it does not slip and cut where you don't want it to, or cut your finger. And if you are designing your own model (rather than a purchased kit) you have to go through the design/draw process anyway. ...R 1 Link to post Share on other sites More sharing options...
RMweb Premium Siberian Snooper Posted September 5, 2017 RMweb Premium Share Posted September 5, 2017 Another plus point, is the accuracy that the machine can attain. I can't see well enough to draw or cut to one or two decimal points. I can achieve that on the screen and it's in the cutting file the machine will get closer than I can measure.

I am quite comfortable and competent using the drawing tools available in Microsoft's Office programs to design my buildings . Could I use them with this cutter? What drawing format would I need to Save As? If these questions have already being answered could you kindly refer me to the relevant pages in this interesting and thorough but very long thread.
