Crash: #262987
BugSplat Reported
Icosahedron Skill Builder (2018)
Abundant scaling/rotation problems…mostly learning curve. However, Sketchup Pro did crash. Brief glimpses of “protractor” filling view and returning to normal size during rotation at time of crash. Additionally, scaling Triangle to Pentagon edge was difficult to align “exactly” with Global Axes.
Model Info: Length and Angle snapping disabled. Format: Fractional
Trying to repeat problem…Sketchup Pro latest Release
It is highly likely my keyboard hand was touching/dragging over touchpad on MacBook Pro 15 with 3-Button Mouse connected. Still having scaling/alignment issues.
The only setting that might be considered helpful would be to turn off Length Snapping in Model Info>Units. Setting Display Precision higher will help you see small dimensions more easily but it has no bearing on how precise your modeling is. Turning off Profiles in the Style or setting Profiles to 1 is also helpful.
The key thing is to use the various tools like Move and Rotate correctly and to enter values when you know them.
The first problem I see is that the triangle you created is incorrect. For a regular icosahedron the faces must be equilateral triangles. Yours aren’t.
A pentagon with the correct side length centered on the origin.(I’ve turned off the axes for the first screen shot. A vertical line from the center and then use the Arc or Pie tool to draw an arc with radius the same as the pentagon side ending on the vertical line.
EXCELLENT! Scaling two components in model was corrupting other component…and I didn’t catch that. This method avoids that and is perfect for me…Idiot proof
Scale can be tricky for things like this because the scaling box aligns with the axes of the context you are working in. If the component is not open for editing the scale box will align with the global axes. If the component is opening for editing the scale box aligns with the component’s axes.
No. The global axes are the ones that are displayed even without any components or groups.
By default the component’s origin will be located at the lower front left of the bounding box and the component’s axes will be parallel to the global axes. When you create a component you can choose to set the component’s origin in a different location and change the orientation of the axes if you wish.
Thank You. It is interesting. Physically constructed a wooden model decades ago…and didn’t quite understand all the “math” to identify the one “component” that could be replicated 84 times to build all the “3-piece” triangles. (Gluing it together was quite an exercise)
Sketchup was still a dream in someone’s mind back then…Just trying to reconstruct in 3D model what I did in my head a while back with compound mitres.
