equal spaces of wrapped area between to parts

Voyager

Hey, I would like to have the equal distance x between the wrapped surface and the two parts.

How can I achieve this?

Thanks!

If it's as simple as a rectangle on a cylinder, I'd model this without wrap. Here are some thought starters. You could use:

• Revolve if you can calculate the angle
• Projected Curve and a Fill surface, Loft or Boundary
• Extrude from an arc to create a surface
• Split in "face" mode using a sketch

If you put the sketch plane for the wrap at the bisector angle between the two gusset shapes, the wrap will stay centered on that area. If you want to explicitly control the X dimension, then some of Evan's suggestions are probably more straightforward. The video along with the help shows the sketch along a normal of the cylinder. https://cad.onshape.com/help/Content/wrap.htm?Highlight=wrap 

Here's a quick example https://cad.onshape.com/documents/7d1a8c0d7cc107ea6a3eb68d/v/d425cdffc132ce701574714f/e/f2c8a592112b17d381a42f8a

Wrap might be overkill with a simple cylinder and a pattern of rectangles. It really depends on what things you'll want to change in the future. If the rectangles are just a placeholder and you want to put some complex shape in that space then it makes sense that wrap might be useful.

Using the wrap technique

Here’s how to adjust the clear distance AKA that X dimension.

1) Open up one of the CLEAR DISTANCE part studios.

2) Go into EDIT for Sketch 3

3) Adjust the upper dimension

To set up the MultiMateConnector

1) Turn on —— CONSTRUCTION   (for visibility during this setup)

2) Definition type —— CENTROID

3) Centroid origin —— EDGES OF CIRCULAR PATTERN   (These are the 2 edges you’re going to center between)

4) Primary axis definition —— FACE NORMAL   (so that the MMC faces the center of whatever you click on in step 5)

5) Primary axis reference faces —— FACE OF EXTRUDE   (Click on the exterior face of the cylinder)

Evan always has great solutions !!

But if you are still wanting to use wrap for some reason — read below 

Use the MultiMateConnector (MMC) featurescript

Using this, you can center a  MMC between the legs. And this MMC will act as a plane to sketch a rectangle, which can then be wrapped

When making the sketch for the rectangle, use the centerpoint rectangle and make the centerpoint of that rectangle coincident with the MMC

This way, if you adjust the thickness of your legs or the width of the rectangle in the sketch, that wrapped rectangle will keep the same clear distance at both of your ‘X’ locations

In the GIF, I adjust the thickness of the legs, and the sketch automatically adjusts around that

Make sure to look at all the part studios 

One last thing. Make sure you look at all the settings for MMC and make sure you have construction selected otherwise you won’t be able to see the mate connector.
