# I converted my part to an implicit but it doesn't look like I expected it to

## Issue:

* When I convert my model to an implicit body it is creating artifacts and fragmented pieces.
* My part has gaps where they were none
* My part looks smaller than the original part
* I imported a surface and converted it to an implicit. The result is very fragmented.

## Cause:

This can be caused by a few things, some of the most common are:

* Tolerance too high
* Errors in mesh/unclean mesh
* Errors from CAD
* Resolution too low
* Surface or thin body converted into an implicit body

## Solution:

* If your tolerance is too high, change it in the block where you are converting it to an Implicit body. This will re-calculate and should get rid of any artifacts.

* If this doesn't improve your part, another method is to convert it to a Mesh. Sometimes the artifacts will disappear in the mesh.
* **Unclean Mesh:** The incomplete look may be caused by meshing errors, creating artifacts. Try using the [Split Mesh](/help-articles/knowledge-base/meshing-workflows/how-to-extract-or-clean-up-mesh-bodies) block to separate out the small, fragmented parts.
* **Converted a surface to an Implicit:** Thin implicit bodies don't show up well graphically. Add a thickness to your part by using the **Thicken Body** block to show a more accurate result. It is best to thicken the part as a first step after converting it to an implicit.
* **Ran a process and it looks odd:** You may need to increase the resolution of your viewport by clicking the menu in the lower-right or using the hot-key CTRL-H to take a high-resolution snapshot of your part.
* **The part has gaps where they shouldn't be any:** Use CTRL-H to see a high-resolution image and see that there aren't any gaps in the implicit, it is just how it shows up graphically.

Still curious about why Implicits behave a little differently? [Check out this blog post](https://ntopology.com/blog/2019/03/12/understanding-the-basics-of-b-reps-and-implicits/) to learn more about them vs typical CAD parts.
