In order to fix your polygon, you'll need to pin down three things:ī) the orientation (usually the easiest is to pick a side and make it horizontal or vertical, but you could also dimension a specific angle relative to something else, or just pick a side and Fix it as described above)Ĭ) the side length.
you're quite right - what you really want is to have the geometry completely fixed. The 'design intent' I imagine would be to have the polygon located relative to something else) (Better practice would normally be to use reference geometry of some sort, so that if you update your model, the polygon would move appropriately. I wouldn't say it's a best practice, but you could simply click the center of your polygon and then use the Fix/UnFix constraint in the sketch palette (looks like a padlock) to pin it down exactly where it is. It's not mandatory that you use this option, but if you do, then you'll have something fixed to reference when you start sketching.Ģ) Fix the polygon center. Check Preferences> Design > Auto project geometry on active sketch plane. If you're sketching on an existing face or workplane, just doublecheck that you're using a point that's projected in from something else. If it's your first sketch, then the model origin should project in as a fixed point. There are 2 potential easy fixes:ġ) Start with a fixed origin. You're asking the right questions, and it sounds like your center point is indeed floating, so start with that.
