move tool with control key held down will copy and paste over and over

I'm happy that helped. I expect there's something the author could have added to make the extension fill automatically. I've forgotten what it is but some other program I use requires the extension to be typed when exporting so I've gotten used to the idea of typing it when I don't see it already there.

Thanks TIG. Larry

I think that's good for 8 hours. You could get further as you develop your method. It does take time to do all that accurately. I find the elevations are limited help in projection, but for a house with such ornamentation I can see the benefit. I have to say that I do not use the interiors as much and I would tend to be doing more on the exterior before working on the interiors (often just model certain rooms). My methods differ some. I often work with an exterior skin and add interiors separately.I tend to make my window and other exterior components and place them based on the floor plan. I extrude profiles for a lot of the elevations work and build the roof using a combination of Instant roof and my own calculations or layout. So in that approach I have left the elevations behind before long. I've been doing some projects where I still use CAD plans but never draw a CAD elevation.The elevations come from the model. That's a beautiful elevation and this is going to be a great house model. Good Luck. Pete! What is this?

I like it.

Wow that's awesome! Definitely go post that in the gallery. I think lots of people would be interested in seeing that and asking about your workflow. Very cool!

Proper craftsmanship in there, my hope is to get a workshop on retirement and build some of the things that interest me, mainly armoured vehicles that never made it to production. Someday perhaps. Thanks for the inspiration.

@dan rathbun said: Is that English, German or both ? the (near to no) GUI is in English, should be feasible for everybody. This release will cease to work if the registry key will change to 'Trimble' with a future SU version. Norbert

Thanks Charly, I will take a look at ThomThoms Cleanup tool. Here the part is located. This just shows the exterior layouts of the aircraft before I work on the internal structure. Thanks, Larry [image: FTZ1_Capture5.JPG]

If your pdf is vector based and you've imported it into Corel you ought to be able to do a deal of pre-processing there to make it SU-friendly. This includes converting any bezier curves into straight line segments. Use the Add Nodes facility to get an acceptable number of segments on each curve, before converting to straight line. When you're done, export it as an early version dwg...like R14, or even R11. This ought to ensure that any overlooked beziers get converted to straight lines too, rather than simply vanishing. Then import into SU. I wouldn't recomend actually using the import as part of your mesh, but you will be able to inference off it very nicely. Pre-processing the beziers ensures that you end up with an sensible number of segments on each curve. You could simply export the whole thing as an early version dwg...but then each curve would contain 1000s of tiny segments instead of maybe a dozen or so.

I don't think so. The 3d version has an option to include guides though...

upstairs_downstairs2.skp. BTW not my tut. See if this helps

Thanks TIG, I was able to reproduce what you did. With the central rail the shape seemed to flatten out to much at the point so I did one without the central rail and it looks better. Seems that the key is that all sections have the same number of segments and determining just how many segments are required to get a smooth surface. I will probably make a mold for this piece and make it out of fiberglass. Thanks, Larry [image: 0L0g_NewTailCone.JPG]

With 360 segments a circle has only 1 degree subtended for each segment, irrespective of the segments' length. With more segments the shorter the segment length for the same radius; but the sensible [self-imposed] upper limit should be something like 1.mm [or a lot less to be practical for large radii!]. The circumference of a circle is 2PIr, so to work backwards from a radius to 1.mm segments use numsegs=(2*Math::PI*radius/1.mm).to_i As the radius increases the number goes up proportionally... radius >>> numsegs 1.mm >>> 6 5.mm >>> 31 10.mm >>> 62 50.mm >>> 314 100.mm >>> 628 1000.mm >>> 6283 etc... Note that ~1591.mm is therefore the radius limit as ~9999 segments gives segments of ~1.mm long. So a circle about 3m/10' across is the limit for 1/mm segments... BUT of course thousands of circle segments translates to many more thousands of edges and facets when it's extruded into 3d... which is a sure fired way to kill your model! So don't be silly!!

You need to 'extract' the profiles/rails into a separate group and then do the EEbyRails. Get the same number of segments in the two rails and profiles. Split the top rail with the straight edge, then divide it so its segmentation mimics the curved edge rail.[image: xhWk_Capture.PNG]

Before chasing the reversed faces I might be inclined to run Delete Coplanar Edges to perhaps reduce the number of faces that need to be reversed.

View > Hidden Geometry OFF. Double-click surface to select the surface and the edges BUT NOT the 'smoothed-edges'. Use Make Group to add it to a new group - it will be automatically be made a copy because the originals are needed by the surface. Edit the Group. View > Hidden Geometry ON. View > Component Edit > Hide Rest of Model You can now see what you are doing. To make the base I did two meshes and then combined them. Draw a line across to make two halves. Select it and Divide into say 10, immediately use Weld.rb to weld it into a 'curve' of 10 segments. This is the 'profile' Draw two short edges away from the apex of each end. Select the outline's edges from one of these to the 'profile' [~1/4], use Weld again to make it a 'curve' - this will be a Rail. Repeat this for the other three pieces of the outline. You now have a straight curve - the profile - and four 'rail' curves - we'll now process these two at a time. Use EEbyRails, pick the profile-curve then two 'rails' on the same side, finish by picking the 'profile' again [i.e. there's no 'melding-profile' for this type of surface!], answer the questions with 'No' unless the mesh faces 'up' - if it does 'reverse' the faces. You now have a mesh of ~half of the bottom face. Repeat to make the other half. Select the two groups and explode them. You now have the bottom-group, explode that and it will heal with the main [original] surface. Select All and group it, so Slicer has something to work on... Note: your surface is quite small so I recommend you first scale up the group x 8, make the slices at 1", then scale everything down by x 0.125... Sketchup has problems with making very small faces BUT they exist no problem when scaled smaller...

Finally had some time to get into this and here is what I have come up with. The tire is too small in width but I can change that. Any comments and tips would be welcome. Larry NewWheelPant.zip

Thanks Dave, I was trying to do it without doing anything to the rib. Larry

If you know a dimension in the drawing such as the height of the cutter profile, you should be able to resize the drawing accurately. Unless you are drawing a profile to use as a pattern for making a cutter, I would suggest keeping the number of segments to a minimum to help keep the model's file size under control.
